An air conditioner according to the present invention comprises: an air-handling unit including a blower fan for supplying an air mixture of outdoor air and indoor air to the indoors, a heat exchanger for exchanging heat between the air mixture blown by the blower fan and cold water, and a temperature sensor for sensing the temperature; and a chiller for supplying cold water to the heat exchanger, and including a compressor, a condenser, an expansion device, and an evaporator connected to the heat exchanger and a water pipe. The chiller communicates with the air-handling unit to set a cold water temperature setting for cold water supplied from the evaporator to the heat exchanger according to the sensed results of the temperature sensor. By varying the operating capacity of the compressor according to the set cold water temperature setting, the benefits of preventing over-dehumidification of indoor areas when the cold water temperature of the heat exchanger is too low, and of consuming a minimal amount of power for performing sufficient indoor cooling, can be achieved. |
