  The calculation of air supply in a cleanroom differs from that of a general HVAC system. HVAC systems determine air supply based on calculated thermal and humidity loads, considering an economical air supply temperature difference to eliminate excess heat and moisture. In contrast, cleanroom air supply is generally calculated independent of thermal and humidity loads. Instead, it is based on the required cleanliness level, considering cross-sectional average airspeed or air changes per hour. If necessary, thermal and humidity load calculations are used for verification, ensuring compliance with heat and moisture elimination requirements. Cleanroom air supply, typically calculated based on cross-sectional average airspeed or air changes, tends to be higher than the air supply calculated for heat and moisture elimination. If the calculated air supply falls short of the requirements for heat and moisture elimination, two solutions are considered: using the air supply calculated for heat
