2. SUBJECT: Communal Hygiene
Theme: "Methods of calculation of the heating, ventilation and lighting projects in residential and public buildings

3. Plan 1
master the technique of sanitary inspection for the heating of residential and public buildings; 2
teach yourself to analyze the methodology of laboratory research indoor air; 3
learn how to properly design the report and records; 4
learn how to develop preventive measures;

4. The student should know
the value of the legal rules governing the relationship of man to man, society and the environment;
apply the basic provisions of each document in its significance;
features of the organization and conduct of sanitary and epidemiological measures to mitigate the adverse effects of risk factors on health and the environment.

5. The student should be able to
conduct sanitary inspection of supervision and make the appropriate accounting and reporting documentation.
justify their actions in solving the problem of the protection of CSS microclimate of residential and public buildings;
to carry out the current sanitary supervision on controlled municipal facilities;

8. In projects of heating, ventilation and air conditioning should provide technical solutions that provide: 1
normalized weather conditions and air quality in the occupied zone residential and public, as well as administrative and residential buildings enterprises 2
normalized weather conditions and air quality in the work area of industrial and warehouse space in buildings of any destination 3
Normalized levels of noise and vibration from the equipment, ventilation and air conditioning 4
application Complete - block equipment and element factory manufacturing systems heating, ventilation and C and also repairability these systems.

9. Thermal insulation construction piping, ductwork and equipment is not permitted to provide any combustible materials with the exception of: 1
painting or film thickness up to 0.4 mm; 2
vapor barrier; 3
coating layers of thermal insulation pipeline construction, located in basements and technical subfield with outputs only the outside of buildings I and II degree of fire resistance at the device inserts a length of 2 m. of non-combustible materials every 30 m. pipe lengths.

10. for the heat period of the year; the design of ventilation in rooms with excess sensible heat - the maximum allowable temperature of, and in the absence of excess heat - a cost-effective within the allowable temperature
for the cold season and transient conditions; in the design of heating - a minimum of acceptable temperatures; the design of ventilation for the assimilation of excess heat - the maximum allowable temperature of, and in the absence of excess heat - a minimum of acceptable temperatures.
Clearing the air temperature in the working area or served in the room should be taken:

11. Heating should be designed to ensure indoor air design temperature within the permissible limits, taking into account: 1
heat loss through the building envelope of buildings and premises in mandatory Appendix 8; 2
heat consumption for heating in the room infiltrating outdoor air in mandatory Appendix 9; 3
consumption of heat for heating of materials, equipment and vehicles 4
heat flow, regularly entering the premises of electric lighting devices, technological equipment, communication materials, from people and other sources; while the heat flux entering the room and kitchen houses, should be taken in the amount of 21 W per 1 m² floor space

12. Pipelines from the manifolds should normally routed separately:
for heating systems with local heating devices
for air curtains and other periodically operating systems or facilities, if they can break the hydraulic resistance of permanent systems.
for ventilation, heating and air conditioning
Pipelines from the manifolds should normally routed separately:

13. 4 dBA or less - for mandatory application №13.
more than 4 dB - less than 1.5 m / s in public buildings and spaces; no more than 2 m / s in the administrative and residential buildings and premises; not more than 3 m / s in industrial buildings and premises;
4 dBA or less - for mandatory application №13.
The speed of flow in the pipes hot water heating systems should be taken according to the permissible equivalent level of sound in the room:

14. The velocity of the steam in the pipes should be
HVAC passing high-pressure steam and condensate motion - 80 m / s and at the opposite - 60 m / s.
HVAC passing low pressure steam and condensate motion - 30 m / s and at the opposite - 20 m / s;
The velocity of the steam in the pipes should be

15. Sectional radiators or single panel;
In areas heaters systems of water and steam heating should be applied with a smooth surface without fins, allowing easy cleaning, including:
Sectional radiators or single panel;
Sectional radiators or twin or single panel for rooms that do not have combustible dust or flammable waste products;
heaters of smooth steel pipes.

17. Batch ventilation with natural impulse through operable windows and openings or with artificial inducement allowed include:
in areas without discharge of harmful substances and substances with pronounced unpleasant odors with the volume per worker 40 cubic meters or more;
technical floors in rooms, tunnels, warehouses, etc., intended for intermittent operation or movement of people.

18. Air conditioning should be taken:
First Class - for Mete rheological conditions required for the process in the economic justification or regulatory requirements;
second class - for Mete rheological conditions within the optimum sanitary or technological standards;
Third class - for Mete rheological conditions within acceptable limits, if they can not be provided with ventilation or intermediate conditions between acceptable or optimal rate with the economic justification.

19. All methods of assessment daylight lasts into two groups:
lighting;
geometric.

20. For other lighting methods include determination of the rate of natural lighting, the angle of the hole, the angle of incidence and depth of emplacement.

21. Test questions For some indicators measured indoor climate?
The magnitude of changes in temperature should not exceed?
Pipe heating systems?
Two-pipe heating system?
Heating systems in residential and public buildings?

22. Continued Features water heating? Features of radiation heating?
Features steam heating?
Central heating system?
Local heating?
