Dongguan clean room has experienced rapid development


How much do you know about the calculation method of Dongguan clean room?

The Dongguan clean room has experienced rapid development in the past so many years. In many industrial branches such as the automotive industry, micro system technology, and biotechnology, it has developed a clean technology suitable for itself, but no matter what clean room technology, There are some basic principles and requirements that everyone must follow, such as positive pressure control. If there is no positive pressure, then there is no basis for all indoor environmental standards and requirements. A well-closed clean room, in the process of use There are four main ways of air leakage:

Air leakage in the gap of the door \ window

2. Leakage when opening the door

3. Air leakage in air shower room \ pass window

4. Indoor process exhaust

Calculation method 1: V = 1.29 (△ P) 1/2

△ V = S * V

△ P: pressure difference between indoor and outdoor (Pa)

V: Wind speed flowing through the gap (m / s)

S: Gap area (M2)

V: leakage air volume through the gap (M3 / h)

Example: Assumed conditions: Room positive pressure 20Pa, door gap length 3.6M, window gap length 40M, assuming gap width of 0.01m

Door gap area S1 = 0.01 * 3.6 = 0.072m2, window gap area S2 = 0.002 * 40 = 0.08m2

Leaked air volume V = S * V = (S1 + S2) * 3600 * 1.29 * (△ P) 1/2 = (0.072 + 0.08) * 3600 * 1.29 * (20)

1/2 = 3157M3 / hr
