Abstract
An air conditioner according to the present invention comprises: a compressor, a condenser, an expander and an evaporator, water pipes connected to said evaporator to supply cold water, and a plurality of chillers to which respective water pipes are connected in parallel to each other. The temperature of the cold water of the chiller in operation from among the plurality of chillers is set in accordance with the difference between a high pressure side and a lower pressure side, and the capacity of the compressor is adjusted in accordance with the set temperature of the cold water. When the difference between the high pressure side and the lower pressure side is higher than a preset level for a preset time and there is a chiller which is not currently in operation, an operating command is transmitted to the chiller which is currently not in operation. Thus, the air conditioner of the present invention operates efficiently in accordance with loads, and power consumption is minimized.
