Discussion on partial circulation air conditioning system used in isolation wards

Presents the some foreign criterion for isolation wards. Through expounding the filtering function of the high efficiency filter on gem and virus and the principle of no leakage return air installation, proves that when the high efficiency filter is fitted in return intakes, the partial circulation air conditioning system can be used in isolation ward. Calculates the energy consumption and economic index of the full fresh air system and partial circulation air conditioning system.
