<p>An air conditioner according to the present invention comprises an air handling unit comprising a fan for supplying the air mixed the indoor air with the outdoor air to the indoor space and a heat exchanger for exchanging the mixed air blowing by the fan with the chilled water and a temperature sensor for sensing temperature, and a chiller which includes a compressor, a condenser, an expansion device and an evaporator and supplies the chilled water from the evaporator to the heat exchanger through a water pipe connecting the evaporator with the heat exchanger, wherein the chiller communicates with the air handling unit and sets a chilled water set temperature of the chilled water supplied from the evaporator to the heat exchanger according to the result sensed by the temperature sensor and changes the driving capacity of the compressor according the chilled water set temperature. Thus, it can prevent super-cooling and excessive dehumidification of the indoor space when a chilled water temperature of a heat-exchanger is too low. In addition, it can perform the sufficient cooling and dehumidification by the minimum electric consumption.</p> |
