PROBLEM TO BE SOLVED: To provide an air conditioning system capable of solving a problem with the occurrence of local high temperature for each rack resulting from high heating and large air volume. SOLUTION: A plurality of racks 1 are installed in a communications equipment room. As necessary, a cooling unit 7 comprising an evaporator and a blower is disposed in these racks 1. In this case, the cooling unit 7 is disposed at any position such as the upper part, middle part, or lower part of the racks, on the top plate of the racks, or on the lower side of a bottom plate. A heat source (refrigerator) 8, a condenser 9, and a refrigerant pump 11 are disposed outdoors, and they are connected to each other through pipes. Also, thermometers, hygrometers, and flowmeters are installed at parts and, based on outputs therefrom, the air volume of the blower for the refrigerant pump 11 and the cooling unit 7 is controlled.
