Patent ID: 7918104

Claim:
A water cooling type air conditioner comprising: a first heat exchanger performing heat exchange between air and refrigerant; a plate type heat exchanger performing heat exchange between the refrigerant and water, the plate type heat exchanger comprising a plurality of thin plates separated by a predetermined interval for forming spaces comprising an inner space in which the water and the refrigerant flow; a refrigerant pipe connected between the first heat exchanger and the plate type heat exchanger, for guiding a flow of the refrigerant; a compressor to compress the refrigerant to a high-temperature and a high-pressure state; a refrigerant controlling valve for changing a flow direction of refrigerant discharged from the compressor toward the first heat exchanger or the plate type heat exchanger according to an operation mode of the water cooling type air conditioner; and a direction controlling unit disposed on one side of the plate type heat exchanger, for changing a flow direction of the refrigerant flowing into the plate type heat exchanger, wherein the direction controlling unit includes a plurality of ports, wherein the plurality of ports includes a first port, a second port, a third port, and a fourth port, wherein each port is directly connected to the refrigerant controlling valve, a refrigerant inlet of the plate type heat exchanger, a refrigerant outlet of the plate type heat exchanger, and the first heat exchanger, respectively.
