At present, most of the cleanrooms in electronic workshops are between class 1000 (iso6) and class 10000 (iso7). The average air exchange rate is 25-60 times / h, the indoor temperature is 22 ± 2 ℃, and the relative humidity is 55 ± 5%.
There are two common ways of air conditioning in the clean room of electronic factory.
1. MHU + AHU + HEPA, referred to as AHU system
2. Mau + FFU + DC, referred to as FFU system
AHU system is used in most of the built electronic plants, while FFU system is used in most of the new plants.
Temperature ± 0.1 ℃ Humidity ± 2%
Through high precision temperature and humidity control for 10 days, the control precision of clean room reaches ± 0.1 ℃ for temperature and ± 2% for humidity;
Climate adaptive logic, regardless of any change in outdoor climate, fresh air unit, fully intelligent undisturbed switching seasonal mode, maintain supply air temperature and humidity stability.
