In an air conditioning apparatus, it includes a clean room (12), an air cleaning section (11), a cooling section (14) and an air mixing section (17). The air cleaning section (14) cleans air to supply to the clean room (14) as cleaned air. The cooling section (14) includes a plurality of cooling units (15) and a plurality of non-cooling units (16) (16). A plurality of cooling units (15) cool air from the clean room (12) to send out as cooled air. A plurality of non-cooling units (16) sends out as non-cooled air from the clean room (12) without cooling air. Each of the quantity of the cooled air and the non-cooled air is determined to compensate an amount of heat generated in the air conditioning apparatus and to reduce a pressure loss given to the air passing through the cooling section (152) to a substantial minimum. The air mixing section (17) mixes the cooled air and the non-cooled air to supply to the air cleaning section (11). The cleaned air is circulated through the clean room (12), the cooling section (14) and the air mixing section (17) to the air cleaning section (11). <IMAGE> |
