Turbulent clean room is generally estimated based on the number of air changes: 100,000 class clean room
Class 1000 dust-free workshop is not less than 50 times / h;
Class 10000 dust-free workshop is not less than 25 times / h;
Class 100,000 dust-free workshop is not less than 15 times / h.
10,000-level ventilation times ≥ 25 times / hour (generally 27-28); 100,000-level ventilation times ≥ 15 times / hour (generally 17-18)
However, the design air volume cannot be carried out blindly according to the number of ventilations, and the residual heat and humidity of the room and process must be considered. Otherwise, the air volume may meet the temperature and humidity requirements at the beginning, and the system will not work so well after a period of operation.
