Document Type and Number:
WIPO Patent Application WO/2018/199682
Kind Code:
A1
Abstract:
The present invention relates to an outdoor unit and a method for controlling the same, the outdoor unit being connected to a refrigerating unit, and two compressors being connected in series to the outdoor unit. An outdoor unit according to an embodiment of the present invention comprises: a low pressure-side compressor for compressing a refrigerant; a high pressure-side compressor for compressing the refrigerant compressed by the low pressure-side compressor; an outdoor heat exchanger for condensing the refrigerant compressed by the high pressure-side compressor; a heat recovery unit for cooling the refrigerant condensed by the outdoor heat exchanger through heat exchange with a refrigerant evaporated by an air conditioning unit; and a supercooler for expanding a part of the refrigerant cooled by the heat recovery unit such that another part of the refrigerant cooled by the heat recovery unit is cooled. Accordingly, the discharge temperature of the low pressure-side compressor and/or the high pressure-side compressor can be decreased.
