Thermal Stability in Cleanrooms: The Air Exchange Rate Connection
Maintaining consistent thermal equilibrium within a cleanroom is essential for accurate process performance. The speed of air exchange, often referred to as the Air Exchange Velocity (AER), directly impacts this heat environment. A higher AER may rapidly remove contaminants but even brings variations in air heat, possibly compromising sensitive fabrication methods. Therefore, precise assessment and control of the AER are needed to obtain the desired degree of purity without substantial temperature swings.
