AIR CONDITIONER

Document Type and Number:

WIPO Patent Application WO/2011/004969

Kind Code:

A3

Abstract:

According to the present invention, an air conditioner comprises: a first compressor and a second compressor which compress a refrigerant through multiple stages; a condenser which condenses the refrigerant compressed by the second compressor; a first flow channel through which a portion of the refrigerant condensed by the condenser passes, in order to be cooled; a supercooling heat exchanger having a second flow channel for exchanging heat with the first flow channel; an expansion instrument which expands the refrigerant cooled by the supercooling heat exchanger; a shell-tube-type evaporator which evaporates the refrigerant expanded by the expansion instrument, and which is connected to a location requiring cold water via a water pipe to supply cold water to said location requiring cold water; a first bypass channel which guides the refrigerant condensed in the condenser to the second flow channel; a supercooling expander installed in the first bypass channel; and a second bypass channel which interconnects the first and second compressors and the second flow channel, thereby decreasing discharge superheat, and thus increasing the degree of subcooling and improving the efficiency of supplying cold water.
