2.2 Determination of ventilation volume
22. The room ventilation volume should be determined based on the number of air changes per hour or the number of new air required per person per hour and the removal of excess heat, excess humidity and harmful gases in the room. 2.2.2 The required number of air changes in the room should comply with the provisions of Table 2.2.2. 2.2.3, the fresh air volume required by each worker should be 30~40m/h. 2.2.4
The required ventilation volume should be calculated based on the residual heat and humidity load discharged from the room. 2.2.5
The ventilation frequency of hazardous areas should be greater than 20 times, and the ventilation frequency of sanitary hazardous areas should be greater than 12 times/h.Room

should also be calculated according to the
waste heat of the removal equipment
In addition to the calculation according to the room ventilation frequency, the ventilation should also be calculated according to the heat dissipation of the main electromechanical equipment. 2.3.1.2 For rooms crowded with electromechanical equipment, local focused air supply can be used, and it can form a good airflow organization with the exhaust duct. 2.3.1.3 Smaller machine rooms can use natural air intake and natural exhaust: other machine rooms should use mechanical air supply and natural exhaust or natural air intake and mechanical exhaust. 2.3.2 Electrical equipment room
2.3.2.1 In addition to calculating the ventilation volume according to the number of room ventilation, it should also be calculated based on the heat dissipation of the electrical equipment and the room's beauty. 2.3.2.2 Smaller electrical equipment rooms can use natural air intake and natural exhaust, and other electrical equipment rooms should use mechanical air supply and natural exhaust (or mechanical exhaust) or natural exhaust and mechanical exhaust.
2.3.3 Battery room
2.3.3.1 In addition to calculating the ventilation volume according to the number of room ventilation, it should also be calculated according to the two requirements of cooling and exhausting hydrogen. And take the larger one. 2.3.3.2 Battery rooms with a total charging power less than or equal to 2kW can use natural ventilation, and the air outlet should be close to the open air: Battery rooms with a total charging power greater than 2W should use mechanical ventilation, and the ventilation device should be explosion-proof and have 100% backup capacity. The air inlet and outlet of the ventilation system should have appropriate devices to prevent water and flames from entering.
2.3.4 Kitchen and toilet room
