Q：If cleanliness requirement is unknown, how do we develop planning on the class of clean room?

A：Strictly, we cannot develop planning in such case. For 「heat value of production equipment」 and 「forced air displacement」 should have to be known as a minimum, or else it’s impossible to select AHU of proper capacity. However, for some domestic employers planning to enter into「clean room for production」, the case of no concept will occur sometimes, what they want to know is 「clean room (Air conditioner) installation is reportedly expensive, how expensive is it ?」, is that true? Proceed with following method for a trial:
a. Reference to domestic (Foreign) standards of the same industry.
b. Reference to summary classifications in Tables 1-10 & 1-11.
c. Adoption of standards for temperature and humidity of common air conditioners.
d. Raise the standard for air change frequency, planning by class 100,000, together with use of the likes of clean shed and clean bench after readiness of production processes.
