Thermal Stability in Cleanrooms: The Air Exchange Rate Connection
Maintaining uniform thermal steadiness within a cleanroom is crucial for accurate process operation. The frequency of air replacement, often referred to as the Air Exchange Rate (AER), closely affects this temperature environment. A greater AER may rapidly eliminate impurities but too introduces variations in air heat, perhaps compromising delicate fabrication processes. Therefore, precise analysis and management of the AER are needed to achieve the needed level of purity excepting substantial warmth oscillations.
