1. Air exchange times in the oil storage room of diesel generator room ≧5 times /h

2. The ventilation frequency of transformer room is 5-8 times /h, and the ventilation frequency of transformer room is 3-4 times/h. ..

3. The number of air changes in the cold room is 4-6 times/h. ..

4. The air exchange rate of oil-fired boiler room and oil-fired direct-fired engine room is ≧3 times /h, and the air exchange rate of emergency ventilation is ≧6 times/h.

5. The air exchange rate of gas-fired boiler room and gas-fired direct-fired engine room is ≧6 times /h, and the air exchange rate of emergency ventilation is ≧ 12 times/h.

6. The ventilation volume of the oil depot should be ≥6 times /h for ventilation; Ventilation between oil pumps should be ≥ 12 times /h for ventilation; When calculating the ventilation of the two, the room height is generally 4 m;

7. The ventilation volume between underground daily fuel tanks should be ≥3 hours/hour for ventilation.

8. The gas pressure regulating metering room shall be provided with a continuous exhaust system, and the ventilation volume shall be ≥3 times /h for ventilation; Emergency ventilation should be ≥ 12 times /h for ventilation.

9. The laundry room can be estimated according to the following air exchange times: the air exchange times in the production room are 20 ~30 times /h, when there are local ventilation facilities, the overall exhaust air volume is 5 times /h, and the air supply volume is 2~3 times/h; The ventilation frequency of the auxiliary room is 15 times/h; The living room shall be implemented according to its relevant specifications.

10. Take air from public toilets 10~ 15 times/h; 5~ 10 times /h ventilated residential toilets and boiling water rooms; For air-conditioned hotel bathrooms, the exhaust air accounts for 80%~90% of the fresh air in the room.

1 1. The smoking room should be provided with mechanical exhaust, and the exhaust volume should be selected according to the ventilation volume of 10~ 15 times/h.

12. In summer, mechanical ventilation or refrigeration (air conditioning with cold source) can be used to cool the elevator room, and the ventilation and cooling air volume can be determined by the air exchange rate method, generally taking 5~ 15 times/h. ..

13. The darkroom should be ventilated by mechanical exhaust and natural air intake, and the exhaust air volume should be ≥5 times/h.. The air outlet should be located near the pool, and the air inlet should use sunshade blinds, and the wind speed passing through the blinds should be

14. The ventilation rate of underground storage room and bicycle garage is 2-4 times/h. ..
