Thermal Stability in Cleanrooms: The Air Exchange Rate Connection
Maintaining consistent temperature stability within a cleanroom is crucial for accurate procedure execution. The frequency of air circulation, often referred to as the Air Exchange Frequency (AER), immediately impacts this temperature environment. A higher AER may rapidly remove impurities but too brings fluctuations in air warmth, possibly jeopardizing delicate production processes. Therefore, precise analysis and regulation of the AER are necessary to achieve the needed level of cleanliness excluding considerable heat fluctuations.
