Thermal Stability in Cleanrooms: The Air Exchange Rate Connection
Maintaining stable thermal stability within a cleanroom is essential for reliable operation performance. The frequency of air circulation, often referred to as the Air Exchange Frequency (AER), directly influences this thermal environment. A greater AER can rapidly extract impurities but even supplies fluctuations in air warmth, potentially jeopardizing delicate manufacturing processes. Therefore, thorough analysis and management of the AER are necessary to secure the required amount of purity excluding substantial temperature swings.
