What are the standards for a class 100 dust-free workshop?
Class 100 dust-free workshop generally needs to be full, specific need to find purification engineer Zhi to calculate the relevant air volume;
However, the air volume can not be designed blindly according to the number of air changes, and the excess heat and humidity of the room and process should be considered.
Otherwise, the air volume may be able to meet the temperature and humidity requirements at the beginning, and the system will not be so good after a period of operation.
Air supply volume and air change times of class 100 dust-free workshop
Air supply volume calculation:
Air supply volume of 100 class vertical laminar flow clean room = section area of clean room 0.25m/s.
100 level laminar flow clean room air supply volume = clean room cross section area 0.35m/s
Turbulence (non-unidirectional flow) Clean room air supply volume = number of clean room volume air exchange.
China's Code for the Design of Clean Plant for Medicine stipulates that the number of air changes in class 10,000 clean rooms is n≥25 times /h, the number of air changes in class 100,000 clean rooms is n≥15 times /h, and the number of air changes in class 300,000 clean rooms is n≥12 times /h. The number of air changes required should be verified according to the calculation of heat balance and air volume balance.
