Draft heating and ventilation in the building block parking garage with storage materials made according to customers commission
and in accordance with the recommendations of the SNIP 41-01-2003, SNIP 41-03-2003, PB 10-573-03, VSN 01-89.
For the design of heating and ventilation of the building block of the parking garage, the following parameters of outside air:
Design temperature for the design of heating and ventilation:
- Winter - On the twentieth,
- Summer: XXXX + S.
The average relative humidity of outside air:
- The coldest month: XX%
- The hottest month: XX%.
The barometric pressure is 745 mm. Hg. Art. (990 hPa).
Estimated wind speed:
- In the summer priod: X m / sec,
- In winter: XXX m / sec.
The source of heat is the heat supply network from the boiler room. Heating medium - water.
Parameters: Tpod = 130 C = 70 C Tobr
In areas of the building block parking garage is designed water two-pipe heating system deadlock.
Options coolant-130/70 C.
As the heaters in the storage room of road equipment and auxiliary transport adopted air-heating units AVO73V1. In other areas the project envisages installation of registers of welded steel pipes f133h4,0, f108h4,0 and f76h3,5 providing normalizable constant temperature in the working and non-working time.
Pipelines heating AVO73V1 isolated.
In areas of the building block parking garage with storage material is designed supply and exhaust mechanical ventilation. Calculation of air exchange is made of the conditions of assimilation of technological hazards.
Hazard are mainly excreted nitrogen oxides.
The premises adopted the scheme of air from the top down. Supply air is supplied from the upper zone to the lower concentration, a jet at an angle of 40 degrees to the horizontal. Venting is carried out from the upper zone - Roof fan (B1-B4), from the lower zone - axial fans (B1 '), established in the basement. Axial fans equipped with dampers, prevents the penetration of outside air into the room when they are disconnected.
Exhaust gases from the engines of motor vehicles operating in the storage room of road equipment installed exhaust reels with sleeves type MER, is attached to a central exhaust system (B6).
The air intake is carried out through a hole in the outer wall of the ventilation chamber (heat input node).
Radiator heating system water supply plants is designed two-pipe stub. Options coolant: 130/70 C.
Pipes are laid on the wall in the room unit heat input. Fixing is carried out to the columns. Vent pipes heating and radiator heating system is carried out at the high points of the automatic air collectors.
Emptying systems made of heat input node and partially on pipelines, through which the evacuation of heat input unit impossible.
Pipelines of heat supply system of air-heating units are insulated with mineral wool mats 40 mm thick with a covering layer of fiberglass.
Before piping insulation cover the primer and paint with oil paint.
Production and acceptance of the work is performed in accordance with the "Manual for the production and acceptance of works on the device of ventilation and air conditioning" (to the SNIP 3.05.01-85).
Conventions adopted in accordance with GOST 21.206-93, 2.785-70 ..
