Thermal Stability in Cleanrooms: The Air Exchange Rate Connection
Maintaining consistent thermal equilibrium within a cleanroom is crucial for accurate process operation. The frequency of air replacement, often referred to as the Air Exchange Rate (AER), directly impacts this heat environment. A greater AER might rapidly extract contaminants but too supplies variations in air temperature, possibly threatening critical production processes. Therefore, thorough assessment and regulation of the AER are required to secure the desired level of purity without substantial temperature oscillations.
