Technical Field

[0002] A clean room is a workshop that has strict requirements on the number of controlled particles, temperature, humidity, pressure, noise and other parameters inside, and has different indicators corresponding to the production requirements of different laboratories. At present, in laboratories or production workshops such as biomedicine, lithium batteries, semiconductors, and cosmetics, production equipment and inspection equipment are generally set up in clean rooms. When designing clean rooms of different cleanliness levels, producers need to calculate the circulating air volume required to meet the cleanliness level based on data such as the space volume of the clean room, the power consumption of the production equipment, and the circulating air volume required for the wet load of the enclosure structure, and design the workshop air conditioning system.
