Biographies Characteristics Analysis

A single set of standards. Organization scheme and options for calculating air exchange in an apartment

The main indicators of the air-thermal comfort of the premises are the composition and purity of the air (air quality) and the microclimate parameters provided by heating, ventilation and air conditioning systems.

Indoor air quality depends on many factors: outdoor air quality; the presence of sources of pollution in the room, the power and location of these sources; the method of organizing air exchange and the design of the ventilation and air conditioning system, the quality of operation of this system, etc.

The air in the room should not contain pollutants in concentrations that are dangerous to human health or cause discomfort. Such contaminants include: various gases, vapors, microorganisms, tobacco smoke and some aerosols, such as dust. Pollutants can enter the premises together with outdoor supply air, from sources of pollutants in the premises, including human waste products, technological processes, furniture, carpets, building and decorative materials.

The current air quality standards (SP 60.13330, industry-specific SPs, documents of the state sanitary and epidemiological supervision of the Russian Federation (see paragraph 2 of this standard)) contain incomplete and sometimes contradictory data.

There are a number of foreign standards, European and American, related to air quality, including the ASHRAE Standard 62.1-2016 Ventilation for Acceptable Indoor Air Quality (Ventilation to ensure acceptable air quality), DIN EN 13779:2007 Ventilation for non-residential buildings - Performance requirements for ventilation and room-conditioning systems, EN 15251:2007 Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment , lighting and acoustics (Input parameters internal environment for design and evaluation energy performance buildings regarding indoor air quality, thermal environment, lighting and acoustics), CIBSE Guide A:2015 Environmental design. Ch. 1. Environmental criteria for design

When developing the "" standard, domestic and foreign regulatory documents were used. ASHRAE Standard 62.1–2016 was used as a prototype as the most complete and reflective of the results latest research in the field of air quality.

In the standard " BUILDINGS RESIDENTIAL AND PUBLIC. Air exchange rates"Two methods are proposed for calculating the minimum air exchange rates sufficient to provide air of acceptable quality in the room:
- a technique based on specific air exchange rates, the domestic analogue of which is the calculation
supply air flow rate according to the rated multiplicity and the rated specific flow rate (Appendix G to SP 60.13330.2016);
- a technique based on the calculation of permissible concentrations of pollutants, a domestic analogue
which is the calculation of the supply air flow by the mass of harmful or explosive substances (Appendix G to SP 60.13330.2016).

The standard attempts to harmonize domestic norms and ASHRAE Standard 62.1–2016.

The application of the norms of the standard does not worsen the quality of indoor air and does not contradict the current regulations. The standard allows you to optimize the amount of air exchange to the outside air in the premises, depending on the specific application conditions.

This standard specifies the norms for the minimum air exchange in the premises of residential buildings during periods when they are not in use; the values ​​of maximum allowable concentrations (MPC) of radioactive gases (radon, thoron) are given; the data given in the first edition has been updated.

Standard " BUILDINGS RESIDENTIAL AND PUBLIC. Air exchange rates"is intended for engineers who design and operate ventilation and air conditioning systems.

ON THE PRINCIPLES AND ORDER OF DEVELOPMENT
AND APPLICATIONS OF ABOK STANDARDS

"ABOK Standards" is the name of technical materials in the field of heating, ventilation, air conditioning, heat and cold supply, thermal protection, microclimate of buildings and structures and their elements, presented in the form of regulatory documents. The name "Standards" was given to them based on the international nature of the content of this term for technical materials presented in the form of regulatory documents, which corresponds to the world practice of developing regulatory documents professional organizations similar profile, for example, ASHRAE , ARI , REHVA , SCANVAC . In Russia, there are names for regulatory documents: “Building Norms and Rules” (SNiP), “Code of Rules for Design and Construction” (SP), which are on different languages will have different spelling and sound.

In international practice, the name of the technical document "Standard", as a rule, corresponds to the recommendatory document in the industry.

NP "ABOK" as a professional association of specialists, the main task which contribute to the progress of the industry, develops ABOK standards with the aim of:

Raising the level of design, construction and operation with a focus on the use of modern technologies in heating and ventilation equipment;

Improving the quality of the microclimate of buildings;

Improving the energy efficiency of buildings;

Harmonization of the domestic regulatory framework with progressive international standards. The system for preparing each ABOK standard includes two stages:

1. Introduction into use of a "temporary" standard with a validity period of 1 year. During this period, its approbation, the collection of comments and suggestions and the preparation of a standard with a validity period of 4 years.

2. Introduction to the use of the standard with a validity period of 4 years, its further improvement and reissue.

ABOK standards have advisory status. NP ABOK strives to ensure their support from the Office of Standardization, Technical Regulation and Certification of the Gosstroy of Russia, Moskomarchitectura, Mosgosexpertiza, as well as other regional organizations interested in using these documents. After a year of approbation, with a positive conclusion on the possibility of their use, ABOK standards are submitted to the relevant organizations for approval and giving them a regional or federal status.

ABOK standards apply to the scope of activities of NP ABOK, and may also apply to other areas of construction.

ABOK standards relate to the design, construction, testing, operation, certification of systems and equipment for heating, ventilation, air conditioning, heat and cold supply, thermal protection, microclimate of buildings and structures and their elements.

NP "AVOK" actively participates in the development of international regulatory and methodological documents and pursues a policy of adapting these documents for Russian conditions if it is economically and practically feasible.

6.7. During the restoration or reconstruction of temples of special architectural and historical and cultural value, when summer temples are transferred to year-round operation, as well as in new temples - monuments of irregular use, the actual values ​​​​of heat transfer resistance of enclosing structures may not meet the requirements of clause 6.2. In this case, the heating and ventilation systems must ensure that condensation does not fall on the inner surfaces of the walls and the covering of the temple.

6.8. The rational arrangement of window blocks along the depth of the light opening in order to exclude the possibility of condensation or freezing of the window slope structure must be determined on the basis of calculations of two-dimensional temperature fields.

6.10. When replacing or installing new fillings of skylights in separate bindings, the inner binding should be sealed in order to protect against the penetration of moisture from the internal air into the interpane space.

6.11. If it is necessary to increase the vapor permeability resistance of the inner layer of the enclosing structure, the vapor barrier layer should be located at the inner surface of the structure no deeper than the plane whose temperature is equal to the dew point temperature of the internal air.

Water heating systems can be designed as vertical one- or two-pipe, with upper (if the interior of the temple allows it) or lower wiring, or horizontal. Pipe laying should be made open, and in cases of possible violation of the interior - hidden.

Heating systems can be performed with natural or artificial circulation of the coolant.

8.13. Heaters of water heating systems are recommended to be installed near the outer walls, under light openings in niches, on the staircase leading to the choir stalls and other rooms, as well as in the basement.

8.14. Air heating units may be equipped with water, steam, electric or fire air heaters.

8.15. Central air heating systems, combined with ventilation, provide a uniform temperature throughout the volume of the serviced premises, which is especially important for heating the head drums. Air supply devices must have increased hydraulic resistance in order to ensure hydraulic stability in air distribution, subject to compliance with the standard noise level. In churches being restored and reconstructed, when installing central heating systems, the existing channels, which were previously intended for fire-air heating, should be used to the maximum.

8.16. Local heating systems are allowed to be carried out using heating cabinets with natural or mechanical stimulation.

8.17. In buildings previously equipped with stove heating, it is allowed to use existing chimneys to remove air.

8.18. Separate systems It is expedient to provide heating for separate areas of the temple, including the choirs and basement, as well as for heated floors.

8.22. In churches with many chapels, it is possible to provide for the maintenance of all premises by a central supply ventilation system with zonal heaters in each chapel.

8.23. It is recommended to use a mechanical ventilation or air conditioning system with an adjustable supply air flow rate that would correspond to heat and moisture inputs for different modes use of the temple. It is advisable to install two ventilation or air conditioning units that would work together at maximum loads and alternately during other periods.

8.24. The amount of air exchange in the premises of the temple should be taken according to Table 3.

8.25. It is recommended to provide separate mechanical exhaust ventilation systems for the following premises of the temple complex: workshops, prosphora, toilet rooms and the basement of the temple.

8.26. For mechanical ventilation and air conditioning systems, noise suppression measures should be provided in accordance with SNiP II-12. The noise level should not exceed 35 dBA. To reduce the level of noise generated by fans, they should be placed in separate rooms with soundproof structures and silencers should be installed on the air ducts.

8.27. In the exhaust shafts it is necessary to install insulated valves with manual or remote control.

8.28. The materials and design of the ventilation ducts and chambers must not facilitate the growth and spread of microorganisms through the ventilation system.

The design of the ventilation system must comply with the requirements of SNiP 41-01.

8.29. The heat balance and air exchange of the central part of the temple are calculated for the conditions of maximum filling of the temple with parishioners (100% of the estimated capacity).

8.30. To draw up a project for an automation system and adjust the control elements of heating, ventilation and air conditioning systems, the calculation is made for the following church occupancy conditions:

  • in the absence of parishioners in the temple;
  • with a minimum filling of the temple with parishioners (10% of the estimated capacity);
  • with an average filling of the temple with parishioners (50% of the estimated capacity).

9. Organization of air exchange

9.1. When organizing air exchange, one should take into account the uneven release of harmful substances in churches associated with the liturgical regime. During the services, the intake of heat, moisture and carbon dioxide (CO) from people, carbon dioxide (CO) and heat from burning candles reach their maximum values. During breaks between services, the concentrations of the above-mentioned receipts are minimal and the temple building is mainly under the influence of external conditions. The organization of air exchange should provide a favorable microclimate for each mode of operation of the temple.

9.2. Supply air in multi-chapel churches is recommended to be distributed zonally to each aisle.

9.3. When choosing the “bottom-up” air exchange arrangement, air should be supplied to the serviced area, at a level not lower than 0.3 m from the floor, in compliance with the requirements for air mobility and the temperature difference between the supply and internal air.

9.4. Removal of air from the premises of the temple should be provided from the upper zone with the help of exhaust openings located in the drums of domes and domes, or through filling in the light openings in the upper zone of the temple. Such a scheme, in addition to the effective removal of moisture, solves the problem of heating the drums of the heads, increasing the temperature on the inner surfaces of the walls, the thermal resistance of which is much lower than for the main structures, and prevents condensation on the surface.

9.5. Exhaust openings located in the drums of heads should be equipped with dampers with electric drives remote control and "non-blown" visors or aeration devices. It is advisable to place aeration devices in the upper fragments of the frames. The location and design of aeration devices is determined by the volume-spatial composition, the features of the external aerodynamics of the building, the "wind rose", the arrangement of window frames and other factors.

9.6. During the periods of festive services, heat and moisture inputs increase many times over. During these periods, in the absence mechanical system ventilation during the transitional and warm periods, natural ventilation should be resorted to by opening existing window openings, taking into account the time of year.

9.7. In the room of the altar in the zone of ignition and suspension of a kindled censer, it is necessary to provide for a local exhaust.

9.8. In churches with choirs in the central part, for their ventilation, it is recommended to design the installation of exhaust fanlights in opposite window openings of the upper zone of the temple.

10. Power supply and automation

The power supply and automation of installations of heating, ventilation, air conditioning and heat supply systems for churches should be provided in accordance with clause 9 of SNiP 41-01.

It is advisable to equip the heating, ventilation (air conditioning) system with a computerized dispatching system, and, if justified, with a computerized control system, assigning the following tasks to them:

  • control over compliance with permissible and optimal parameters of indoor air;
  • control over the temperature of the internal surfaces of enclosing structures;
  • issuing recommendations on the optimal management of the process of heating, ventilation (air conditioning) or natural ventilation;
  • ensuring the economical use of energy resources for the heat supply of the temple.

The computer system must perform the functions of security and fire alarms.

11. Fire safety

Requirements for fire safety ventilation, heating and heat supply systems in churches must comply with SNiP 21-01 and NPB 108.

liturgical time- the time when divine services, prayers and trebs are performed inside the temple. Off-duty time- the rest of the time when the temple is open to individual parishioners.

Regulated ventilation of unheated temples is carried out in the spring to warm and dry the premises, as well as to remove musty odors formed during the winter period when the temple was not in use.

For unheated temples in the spring, as a result of the entry of warm and humid outside air into the premises, there is a danger of condensation on the internal surfaces of massive enclosing structures that have cooled down during the winter period.

A necessary condition for the possibility of ventilation of temples is to ensure the conditions for non-condensation on the inner surfaces of walls and interior items.

Controlled ventilation of unheated temples was known in ancient Russia, and in Novgorod it was used until the beginning of the last century. There was the following original and fairly accurate in terms of physical essence method for determining the possibility of airing unheated temples. In the coldest part of the building there was a massive glass bottle of water, which was periodically taken out into the street. If at the same time the glass fogged up, this meant that the outside air, getting inside the temple, in contact with interior elements that have the same surface temperature as the bottle, would lead to condensation. That is, it is impossible to carry out ventilation during such periods.

In order to practically determine the possibility of ventilation of the temple, it is necessary to hang a psychrometer inside the temple to measure the temperature of the internal air using a dry and wet thermometer and have an aspiration psychrometer, for example, an Asman psychrometer, to determine the temperature, humidity and moisture content of the outside air.

Airing an unheated temple in the spring is allowed under the following conditions:

ABOUT THE PRINCIPLES AND PROCEDURE FOR THE DEVELOPMENT AND APPLICATION OF ABOK STANDARDS

"ABOK Standards" is the name of technical materials in the field of heating, ventilation, air conditioning, heat and cold supply, thermal protection, microclimate of buildings and structures and their elements, presented in the form of regulatory and methodological documents. The name "Standards" was given to them based on the international nature of the content of this term for technical materials, which corresponds to the world practice of developing such documents by professional organizations of a similar profile, for example, ASHRAE , ARI , REHVA , SCANVAC . In Russia, there are names for regulatory documents: GOSTs "Building Norms and Rules" (SNiP), "Code of Rules for Design and Construction" (SP), which in different languages ​​will have different spellings and sounds.

In international practice, the name of the technical document "Standard", as a rule, corresponds to the recommendatory document in the industry.

NP "ABOK" as a professional association of specialists, whose main task is to promote the progress of the industry, develops ABOK standards in order to improve the level of design, construction and operation with a focus on the use of modern technologies in heating and ventilation equipment due to:

Improving the quality of the microclimate of buildings;

Improving the energy efficiency of buildings;

Harmonization of the domestic regulatory framework with progressive international standards.

The system for preparing each ABOK standard includes two stages:

1 . Introduction into use of a "temporary" standard with a validity period of 1 year. During this period, its approbation, the collection of comments and suggestions and the preparation of a standard with a validity period of 4 years.

2 . Introduction to the use of the standard with a validity period of 4 years, its further improvement and reissue.

In the development of standards and their further use, NP "AVOK" received approval from the Office of Standardization, Technical Regulation and Certification of the Gosstroy of Russia, Moscomarchitecture, Moscow State Expertise, as well as other regional organizations interested in using documents of this kind. After a year of approbation, with a positive conclusion on the possibility of their use, ABOK standards are submitted to the relevant organizations for approval and giving them a regional or federal status.

ABOK standards apply to the scope of activities of NP ABOK, as well as to other areas of construction.

ABOK standards relate to the design, construction, testing, operation, certification of systems and equipment for heating, ventilation, air conditioning, heat and cold supply, thermal protection, microclimate of buildings and structures and their elements.

NP AVOK actively participates in the development of international regulatory and methodological documents and pursues a policy of adapting these documents to Russian conditions, if it is economically and practically feasible.

AIR CHANGE RATE

Foreword

The main indicators of the air-thermal comfort of the premises are the composition and purity of the air (air quality) and the microclimate parameters provided by heating, ventilation and air conditioning systems.

Indoor air quality depends on many factors: outdoor air quality; the presence of sources of pollution in the room, the power and location of these sources; the method and design of the ventilation and air conditioning system, the methods of control and the quality of operation of this system, etc.

The air in the room should not contain pollutants in concentrations that are dangerous to human health or cause discomfort. Such contaminants include: various gases, vapors, microorganisms, tobacco smoke and some aerosols, such as dust. Pollutants can enter the premises together with outdoor supply air, from sources of pollutants in the premises, including human waste products, technological processes, furniture, carpets, building and decorative materials.

The air quality standards in force today (SNiP 41-01-2003, industry-specific SNiP, VSN and SN, documents of the state sanitary and epidemiological supervision of the Russian Federation (app. pp. -)) contain incomplete and sometimes contradictory data.

There are a number of foreign standards, European and American (app. No. - ), related to air quality, including the standard ASHRAE (American Association of Heating, Refrigeration, Ventilation, and Air Conditioning Engineers), developed in 1999 (app. p.).

When developing this standard, domestic and foreign standards were used. The standard was used as a prototype ASHRAE 62-1999 Ventilation for Acceptable Indoor Air Quality» as the most complete and reflects the results of the latest research in the field of air quality.

The standard proposes two methods for calculating the minimum air exchange rates sufficient to provide indoor air of acceptable quality:

A technique based on specific air exchange rates, the domestic analogue of which is the calculation of the supply air flow rate according to the normalized multiplicity and specific flow rate (Appendix M SNiP 41-01-2003, industry SNiP, VSN and SN);

A technique based on the calculation of permissible concentrations of pollutants, the domestic analogue of which is the calculation of the consumption of cloying air by the mass of harmful substances (Appendix L SNiP 41-01-2003).

The standard attempts to harmonize domestic norms and norms of the standard ASHRAE 62-1999.

The application of the norms of the standard does not worsen the quality of indoor air and does not contradict the current regulations. The standard allows you to optimize the amount of air exchange to the outside air in the premises, depending on the specific application conditions.

The second edition of the standard clarifies the norms for the minimum air exchange in the premises of residential buildings during periods when the premises are not in use; the norms of the minimum air exchange in the premises of public buildings are presented in a more convenient form; the values ​​of maximum allowable concentrations (MPC) of radioactive gases are given(radon, thoron); Corrected inaccuracies that were present in the first edition.

The standard is intended for engineers who design and operate ventilation and air conditioning systems.

1 area of ​​use

1.1 . This standard establishes the minimum air exchange rates for outside air (outside air flow rates) that ensure the necessary purity (quality) of air in the serviced premises and its minimum possible adverse effect on human health. The minimum air exchange rates are not calculated.

1.2 . The air quality in the premises must be ensured regardless of the adopted ventilation system and the scheme for organizing air exchange.

1.3 . This standard applies to all rooms that people can occupy in residential and public buildings, with the exception of rooms for which other regulations or special conditions require more air exchange than established in this standard.

1.4 . This standard applies to all premises in which the microclimate parameters are provided in accordance with the requirements GOST 30494-96 , SNiP 31-01-2003 "Residential multi-apartment buildings", SNiP 2.08.02-89* "Public buildings and structures", SNiP 31-05-2003 "Public administrative buildings", MGSN 3.01-01 "Residential buildings".

1.5 . This standard deals with chemical, physical and biological pollutants entering, emitting or generated indoors that can affect air quality.

1.6 . This International Standard does not deal with factors affecting human perception of air quality, such as:

Unidentified and unstudied pollutants;

Differences in susceptibility in different people, psychological stress, etc.

1.7 . The standard proposes two methods for calculating the minimum air exchange rate required to provide indoor air of acceptable quality:

1.7.1 . Technique based on specific norms of air exchange.

The necessary air quality is ensured by supplying a certain amount of outside air into the room, depending on the purpose of the room and its mode of operation. This technique is recommended to be used to calculate the amount of air exchange in premises where, as a rule, it is not expected to change their purpose, the magnitude and nature of pollutants entering the premises during operation.

1.7.2 . Methodology based on the calculation of permissible concentrations of pollutants.

The necessary air quality is ensured by supplying a certain amount of outside air into the premises, depending on the magnitude and nature of pollutants in the premises. This technique is recommended to be used to calculate the amount of air exchange in rooms that may change their purpose and / or mode of operation during operation, in which intense sources of pollutants may be present or appear, etc.

The project documentation should indicate which of the methods used in the calculation of air exchange.

2. Regulatory references

3. Terms and definitions

Terms and definitions referred to in the text are given in App. .

4. General technical requirements

4.1 . The minimum necessary air exchange, sufficient to maintain the required air quality in the serviced areas of the premises, should be provided by a system of natural or mechanical ventilation (air conditioning) by supplying outside air and removing air that has assimilated pollutants in the premises.

4.2 . Required quality air in the serviced areas of the premises should be provided for all modes of use of the premises and the corresponding modes of operation of the ventilation systems.

4.4 . The scheme for organizing air exchange in the premises should ensure the distributionremoval of supply air, excluding its flow through areas with high pollution to areas with less pollution.

4.5 .

4.6 . Stationary local sources of harmful emissions should, as a rule, be equipped with local exhausts.

4.7 . The calculated air exchange in the premises should be taken as the largest of the supply and exhaust air costs for any mode of use of the premises.

4.8 . Outdoor air intakes and exhaust air emissions should be arranged in accordance with the requirements SNiP 41-01-2003.

4.9 . The materials and design of ventilation ducts and chambers should minimize conditions that allow the growth and spread of microorganisms through the ventilation system. The design of the ventilation system must comply with the requirements SNiP 41-01-2003.

5. Methods for determining the norms of air exchange

5.1. Technique based on specific norms of air exchange.

Permissible outdoor air quality, determined by the MPC value of pollutants in the outdoor air;

Norms of specific air exchange in the premises of residential and public buildings;

Modes of operation of ventilation (air conditioning) systems under variable loads and / or with periodic use of premises.

5.1.1 . The concentration of harmful substances in the outdoor (atmospheric) air used for ventilation (conditioning) should not exceed the MPC in the air of populated areas.

MPC values ​​should be taken in accordance with GN 2.1.6.695-98, GN 2.1.6.696-98, GN 2.1.6.716-98, GN 2.1.6.7135-98, GN 2.1.6.789-99, GN 2.1.6.790-99.

MPC values ​​for pollutants most frequently present in atmospheric air are presented in Table. .

In the case of the joint presence in the atmospheric air of several harmful substances that have a summation of action, the sum of their relative concentrations, calculated according to the following formula, should not exceed 1:

Here C i- concentration valuei-th pollutant in the outside air, mg/m 3 .

5.1.2 . If the level of outdoor air pollution exceeds the figures given in Table. , it needs to be cleaned.

In cases where existing cleaning technologies do not provide the required purity of outdoor air, a short-term (for example, during rush hours on roads) decrease in the amount of outdoor air is allowed.

5.1.3 . An acceptable air quality will be ensured in the room if the established norms of specific air exchange are observed in it (Table 1). and ).

Notes:

1 . If it is known or suspected that unusual pollutants or their sources are present in the room, the amount of air exchange should be established using a methodology based on the calculation of permissible concentrations of pollutants.

2. In table. and the norms of specific air exchange are presented in m 3 / h per person or m 3 / h× m 2 rooms.

In most cases, the amount of pollutants is taken in proportion to the number of people in the room.

In cases where the norms of specific air exchange are presented in m 3 / h× m 2 and it is known that the number of people in the room differs from the “standard” value, air exchange rates per person should be used for the expected number of people in the room.

3 . Rates of specific air exchange in table. and for the premises presented in them are installed in such a way that when the outdoor air of the required quality is supplied, human biofluents (particulate matter, odors and other pollutants common to the premises presented in them) are diluted, and an acceptable level of indoor air quality is achieved.

The criteria for comfort (including odour) considering biofluents are likely to be met if the air exchange is sufficient to maintain the indoor carbon dioxide concentration no more than 1250 mg/m 3 above the outdoor carbon dioxide concentration.

4 . Specific air exchange rates cannot be reduced when using recirculated air.

5 . Rates of specific air exchange (Table. and ) determine the requirements for outdoor air in the premises occupied by people with air exchange arrangements that ensure good air mixing in the room(coefficient of air exchange efficiency To q = 1).

For schemes with To q > 1, as a rule, this is possible when air is supplied to the serviced area of ​​public buildings through floor-mounted perforated air diffusers, a methodology should be applied based on the calculation of permissible concentrations of pollutants (p. ).

6 . A possible scheme for organizing air exchange in an apartment and options for its calculation are presented in the reference appendix. .

5.1.6 . If the pollution of the premises is associated only with the presence of people and their activities, which do not create a health hazard in the short term, then the supply of outdoor air may lag behind the start of use of the premises.

The lag time, the time lag can be determined from the graph in Fig. .

5.1.7 . If the pollution of the premises is associated with the presence of sources of pollution in it that are not related to the presence of people and their activities, the supply of outside air must precede the start of use of the premises.

The start time of outdoor air supply can be determined from the graph in fig. .

5.1.8 . If the maximum pollution of the room lasts less than 3 hours during the working day, the outdoor air flow can be determined by average pollution, but not less than half of the maximum value.

5.2. Methodology based on the calculation of permissible concentrations of pollutants

This methodology establishes:

- acceptable outdoor air quality;

- ways of processing outside air, if necessary;

- the amount of outside air depending on the amount of pollutants entering the room. MPC of some pollutants in the served area of ​​the premises is presented in Table. .

5.2.1 . Outside air consumption by mass of pollutants should be taken as the largest of those calculated by the formula adj. LSNiP 41-01-2003 :

,

whereL - outdoor air consumption, m 3 / h;

L M O - air flow rate removed from the serviced area by local exhausts from the equipment, m 3 / h;

m PO - consumption of each pollutant entering the room, kg/h.

With the simultaneous entry into the room of several pollutants with a summation of action, the outdoor air flow rate should be taken equal to the sum of the outdoor air flow rates calculated for each substance:

q O W - maximum allowable concentration of a pollutant in the service area, mg/m 3 ;

q H - concentration harmful substance in the outside air, mg / m 3;

q UD - concentration of harmful substances in the removed air, mg/m 3 .

The concentration of a harmful substance in the exhaust air should be calculated using the formula

,

whereK q - coefficient of efficiency of air exchange in the room.

For indoor air exchange schemes with a height gradient of pollutant concentrations, as a rule, this is possible when air is supplied to the serviced area of ​​public buildings through floor perforated air distributors (displacement ventilation)K q > 1 and is determined by calculation.

An example of calculating the air exchange in a room is presented in the reference appendix. .

ABOUT THE PRINCIPLES AND PROCEDURE FOR THE DEVELOPMENT AND APPLICATION OF ABOK STANDARDS

"ABOK Standards" is the name of technical materials in the field of heating, ventilation, air conditioning, heat and cold supply, thermal protection, microclimate of buildings and structures and their elements, presented in the form of regulatory and methodological documents. The name "Standards" was given to them based on the international nature of the content of this term for technical materials, which corresponds to the world practice of developing such documents by professional organizations of a similar profile, for example, ASHRAE , ARI , REHVA , SCANVAC . In Russia, there are names for regulatory documents: GOSTs "Building Norms and Rules" (SNiP), "Code of Rules for Design and Construction" (SP), which in different languages ​​will have different spellings and sounds.

In international practice, the name of the technical document "Standard", as a rule, corresponds to the recommendatory document in the industry.

NP "ABOK" as a professional association of specialists, whose main task is to promote the progress of the industry, develops ABOK standards in order to improve the level of design, construction and operation with a focus on the use of modern technologies in heating and ventilation equipment due to:

Improving the quality of the microclimate of buildings;

Improving the energy efficiency of buildings;

Harmonization of the domestic regulatory framework with progressive international standards.

The system for preparing each ABOK standard includes two stages:

1 . Introduction into use of a "temporary" standard with a validity period of 1 year. During this period, its approbation, the collection of comments and suggestions and the preparation of a standard with a validity period of 4 years.

2 . Introduction to the use of the standard with a validity period of 4 years, its further improvement and reissue.

In the development of standards and their further use, NP "AVOK" received approval from the Office of Standardization, Technical Regulation and Certification of the Gosstroy of Russia, Moscomarchitecture, Moscow State Expertise, as well as other regional organizations interested in using documents of this kind. After a year of approbation, with a positive conclusion on the possibility of their use, ABOK standards are submitted to the relevant organizations for approval and giving them a regional or federal status.

ABOK standards apply to the scope of activities of NP ABOK, as well as to other areas of construction.

ABOK standards relate to the design, construction, testing, operation, certification of systems and equipment for heating, ventilation, air conditioning, heat and cold supply, thermal protection, microclimate of buildings and structures and their elements.

NP AVOK actively participates in the development of international regulatory and methodological documents and pursues a policy of adapting these documents to Russian conditions, if it is economically and practically feasible.

AIR CHANGE RATE

Foreword

The main indicators of the air-thermal comfort of the premises are the composition and purity of the air (air quality) and the microclimate parameters provided by heating, ventilation and air conditioning systems.

Indoor air quality depends on many factors: outdoor air quality; the presence of sources of pollution in the room, the power and location of these sources; the method and design of the ventilation and air conditioning system, the methods of control and the quality of operation of this system, etc.

The air in the room should not contain pollutants in concentrations that are dangerous to human health or cause discomfort. Such contaminants include: various gases, vapors, microorganisms, tobacco smoke and some aerosols, such as dust. Pollutants can enter the premises together with outdoor supply air, from sources of pollutants in the premises, including human waste products, technological processes, furniture, carpets, building and decorative materials.

The air quality standards in force today (SNiP 41-01-2003, industry-specific SNiP, VSN and SN, documents of the state sanitary and epidemiological supervision of the Russian Federation (app. pp. -)) contain incomplete and sometimes contradictory data.

There are a number of foreign standards, European and American (app. No. - ), related to air quality, including the standard ASHRAE (American Association of Heating, Refrigeration, Ventilation, and Air Conditioning Engineers), developed in 1999 (app. p.).

When developing this standard, domestic and foreign standards were used. The standard was used as a prototype ASHRAE 62-1999 Ventilation for Acceptable Indoor Air Quality» as the most complete and reflects the results of the latest research in the field of air quality.

The standard proposes two methods for calculating the minimum air exchange rates sufficient to provide indoor air of acceptable quality:

A technique based on specific air exchange rates, the domestic analogue of which is the calculation of the supply air flow rate according to the normalized multiplicity and specific flow rate (Appendix M SNiP 41-01-2003, industry SNiP, VSN and SN);

A technique based on the calculation of permissible concentrations of pollutants, the domestic analogue of which is the calculation of the consumption of cloying air by the mass of harmful substances (Appendix L SNiP 41-01-2003).

The standard attempts to harmonize domestic norms and norms of the standard ASHRAE 62-1999.

The application of the norms of the standard does not worsen the quality of indoor air and does not contradict the current regulations. The standard allows you to optimize the amount of air exchange to the outside air in the premises, depending on the specific application conditions.

The second edition of the standard clarifies the norms for the minimum air exchange in the premises of residential buildings during periods when the premises are not in use; the norms of the minimum air exchange in the premises of public buildings are presented in a more convenient form; the values ​​of maximum allowable concentrations (MPC) of radioactive gases are given(radon, thoron); Corrected inaccuracies that were present in the first edition.

The standard is intended for engineers who design and operate ventilation and air conditioning systems.

1 area of ​​use

1.1 . This standard establishes the minimum air exchange rates for outside air (outside air flow rates) that ensure the necessary purity (quality) of air in the serviced premises and its minimum possible adverse effect on human health. The minimum air exchange rates are not calculated.

1.2 . The air quality in the premises must be ensured regardless of the adopted ventilation system and the scheme for organizing air exchange.

1.3 . This standard applies to all rooms that people can occupy in residential and public buildings, with the exception of rooms for which other regulations or special conditions require more air exchange than established in this standard.

1.4 . This standard applies to all premises in which the microclimate parameters are provided in accordance with the requirements GOST 30494-96 , SNiP 31-01-2003 "Residential multi-apartment buildings", SNiP 2.08.02-89* "Public buildings and structures", SNiP 31-05-2003 "Public administrative buildings", MGSN 3.01-01 "Residential buildings".

1.5 . This standard deals with chemical, physical and biological pollutants entering, emitting or generated indoors that can affect air quality.

1.6 . This International Standard does not deal with factors affecting human perception of air quality, such as:

Unidentified and unstudied pollutants;

Differences in susceptibility in different people, psychological stress, etc.

1.7 . The standard proposes two methods for calculating the minimum air exchange rate required to provide indoor air of acceptable quality:

1.7.1 . Technique based on specific norms of air exchange.

The necessary air quality is ensured by supplying a certain amount of outside air into the room, depending on the purpose of the room and its mode of operation. This technique is recommended to be used to calculate the amount of air exchange in premises where, as a rule, it is not expected to change their purpose, the magnitude and nature of pollutants entering the premises during operation.

1.7.2 . Methodology based on the calculation of permissible concentrations of pollutants.

The necessary air quality is ensured by supplying a certain amount of outside air into the premises, depending on the magnitude and nature of pollutants in the premises. This technique is recommended to be used to calculate the amount of air exchange in rooms that may change their purpose and / or mode of operation during operation, in which intense sources of pollutants may be present or appear, etc.

The project documentation should indicate which of the methods used in the calculation of air exchange.

2. Regulatory references

3. Terms and definitions

Terms and definitions referred to in the text are given in App. .

4. General technical requirements

4.1 . The minimum necessary air exchange, sufficient to maintain the required air quality in the serviced areas of the premises, should be provided by a system of natural or mechanical ventilation (air conditioning) by supplying outside air and removing air that has assimilated pollutants in the premises.

4.2 . The required air quality in the serviced areas of the premises must be ensured under all modes of use of the premises and the corresponding modes of operation of the ventilation systems.

4.4 . The scheme for organizing air exchange in the premises should ensure the distributionremoval of supply air, excluding its flow through areas with high pollution to areas with less pollution.

4.5 .

4.6 . Stationary local sources of harmful emissions should, as a rule, be equipped with local exhausts.

4.7 . The calculated air exchange in the premises should be taken as the largest of the supply and exhaust air costs for any mode of use of the premises.

4.8 . Outdoor air intakes and exhaust air emissions should be arranged in accordance with the requirements SNiP 41-01-2003.

4.9 . The materials and design of ventilation ducts and chambers should minimize conditions that allow the growth and spread of microorganisms through the ventilation system. The design of the ventilation system must comply with the requirements SNiP 41-01-2003.

5. Methods for determining the norms of air exchange

5.1. Technique based on specific norms of air exchange.

Permissible outdoor air quality, determined by the MPC value of pollutants in the outdoor air;

Norms of specific air exchange in the premises of residential and public buildings;

Modes of operation of ventilation (air conditioning) systems under variable loads and / or with periodic use of premises.

5.1.1 . The concentration of harmful substances in the outdoor (atmospheric) air used for ventilation (conditioning) should not exceed the MPC in the air of populated areas.

MPC values ​​should be taken in accordance with GN 2.1.6.695-98, GN 2.1.6.696-98, GN 2.1.6.716-98, GN 2.1.6.7135-98, GN 2.1.6.789-99, GN 2.1.6.790-99.

The MPC values ​​of the pollutants most frequently present in the atmospheric air are presented in Table. .

In the case of the joint presence in the atmospheric air of several harmful substances that have a summation of action, the sum of their relative concentrations, calculated according to the following formula, should not exceed 1:

Here C i- concentration valuei-th pollutant in the outside air, mg/m 3 .

5.1.2 . If the level of outdoor air pollution exceeds the figures given in Table. , it needs to be cleaned.

In cases where existing cleaning technologies do not provide the required purity of outdoor air, a short-term (for example, during rush hours on roads) decrease in the amount of outdoor air is allowed.

5.1.3 . An acceptable air quality will be ensured in the room if the established norms of specific air exchange are observed in it (Table 1). and ).

Notes:

1 . If it is known or suspected that unusual pollutants or their sources are present in the room, the amount of air exchange should be established using a methodology based on the calculation of permissible concentrations of pollutants.

2. In table. and the norms of specific air exchange are presented in m 3 / h per person or m 3 / h× m 2 rooms.

In most cases, the amount of pollutants is taken in proportion to the number of people in the room.

In cases where the norms of specific air exchange are presented in m 3 / h× m 2 and it is known that the number of people in the room differs from the “standard” value, air exchange rates per person should be used for the expected number of people in the room.

3 . Rates of specific air exchange in table. and for the premises presented in them are installed in such a way that when the outdoor air of the required quality is supplied, human biofluents (particulate matter, odors and other pollutants common to the premises presented in them) are diluted, and an acceptable level of indoor air quality is achieved.

The criteria for comfort (including odour) considering biofluents are likely to be met if the air exchange is sufficient to maintain the indoor carbon dioxide concentration no more than 1250 mg/m 3 above the outdoor carbon dioxide concentration.

4 . Specific air exchange rates cannot be reduced when using recirculated air.

5 . Rates of specific air exchange (Table. and ) determine the requirements for outdoor air in the premises occupied by people with air exchange arrangements that ensure good air mixing in the room(coefficient of air exchange efficiency To q = 1).

For schemes with To q > 1, as a rule, this is possible when air is supplied to the serviced area of ​​public buildings through floor-mounted perforated air diffusers, a methodology should be applied based on the calculation of permissible concentrations of pollutants (p. ).

6 . A possible scheme for organizing air exchange in an apartment and options for its calculation are presented in the reference appendix. .

Rice. one. Maximum allowable ventilation delay time

Example: air flow - 60 m 3 /h× people; room volume - 30 m 3 / person; admissible ventilation delay time - 0.6 h.

5.1.4 . Rooms equipped with exhaust systems (kitchens, bathrooms, toilets, smoking rooms, etc.) can use the air supplied through adjacent rooms to compensate for the exhaust air. The quality of the supply air must meet the requirements of Table. .

Rice. 2 . Minimum required ventilation time before filling the room

Example: air flow - 30 m 3 / h× people; room volume - 3.5 m 3 / person; admissible ventilation delay time - 0.5 h.

5.1.5 . The supply of outside air to the premises is not necessary if the premises are not in use and there are no sources of pollution that are not related to the presence of people and their activities (for example, pollution from building materials, furnishings, etc.).

5.1.6 . If the pollution of the premises is associated only with the presence of people and their activities, which do not create a health hazard in the short term, then the supply of outdoor air may lag behind the start of use of the premises.

The lag time, the time lag can be determined from the graph in Fig. .

5.1.7 . If the pollution of the premises is associated with the presence of sources of pollution in it that are not related to the presence of people and their activities, the supply of outside air must precede the start of use of the premises.

The start time of outdoor air supply can be determined from the graph in fig. .

5.1.8 . If the maximum pollution of the premises lasts less than 3 hours during the working day, the outdoor air flow can be determined by the average value of pollution, but not less than half of the maximum value.

5.2. Methodology based on the calculation of permissible concentrations of pollutants

This methodology establishes:

- acceptable outdoor air quality;

- ways of processing outside air, if necessary;

- the amount of outside air depending on the amount of pollutants entering the room. MPC of some pollutants in the served area of ​​the premises is presented in Table. .

5.2.1 . Outside air consumption by mass of pollutants should be taken as the largest of those calculated by the formula adj. LSNiP 41-01-2003 :

,

whereL - outdoor air consumption, m 3 / h;

L M O - air flow rate removed from the serviced area by local exhausts from the equipment, m 3 / h;

m PO - consumption of each pollutant entering the room, kg/h.

With the simultaneous entry into the room of several pollutants with a summation of action, the outdoor air flow rate should be taken equal to the sum of the outdoor air flow rates calculated for each substance:

q O W - maximum allowable concentration of a pollutant in the service area, mg/m 3 ;

q H - concentration of a harmful substance in the outside air, mg/m 3 ;

q UD - concentration of harmful substances in the removed air, mg/m 3 .

The concentration of a harmful substance in the exhaust air should be calculated using the formula

,

whereK q - coefficient of efficiency of air exchange in the room.

For indoor air exchange schemes with a height gradient of pollutant concentrations, as a rule, this is possible when air is supplied to the serviced area of ​​public buildings through floor perforated air distributors (displacement ventilation)K q > 1 and is determined by calculation.

An example of calculating the air exchange in a room is presented in the reference appendix. .
