Air conditioner

摘要

An air conditioner having a first circulation channel which drives a thermodynamic cycle while normally circulating a refrigerant, a second circulation channel which is branched from an outlet of a condenser of the first circulation channel to recover oil from the refrigerant to a compressor and to cause the refrigerant to pass through a supercooling heat exchanger, and a third circulation channel which is directly branched from an evaporator of the first circulation channel to recover oil from the refrigerant and to the compressor and to cause the refrigerant to pass through the supercooling heat exchanger, thereby preventing the wet compression of the compressor to achieve improved reliability of the compressor, and preventing the degradation of heat-exchange performance.

主权项

1. An air conditioner comprising:
a first circulation channel in which a refrigerant sequentially circulates a compressor, a condenser, an expansion instrument, and an evaporator to implement a refrigerating cycle; a supercooling heat exchanger disposed between the condenser and the expansion instrument, wherein the first circulation channel passes within the supercooling heat exchanger; a second circulation channel which is branched from the first circulation channel between the condenser and the supercooling heat exchanger, passes within the supercooling heat exchanger, and connected to the compressor; and a third circulation channel which is directly branched from within the evaporator, passes within the supercooling heat exchanger, and is connected to the compressor, wherein the refrigerant flowing in the first circulation channel, the refrigerant flowing in the second circulation channel, and the refrigerant flowing in the third circulation channel are heat exchanged each other within the supercooling heat with exchanger.
