Thermal Stability in Cleanrooms: The Air Exchange Rate Connection
Maintaining consistent temperature equilibrium within a cleanroom is vital for dependable process operation. The frequency of air replacement, often referred to as the Air Exchange Velocity (AER), directly influences this heat environment. A higher AER can rapidly remove particles but too introduces changes in air temperature, possibly jeopardizing critical fabrication processes. Therefore, thorough analysis and regulation of the AER are required to secure the required degree of cleanliness excluding substantial heat oscillations.
