Abstract: The present invention relates to a cooling system for a low temperature storage. The cooling system for the low temperature storage according to an embodiment of the present invention comprises: a first outdoor valve disposed between a compressor and an outdoor heat exchanger and selectively restricting an inflow of a refrigerant into the outdoor heat exchanger; and a first bypass pipe branched from an inlet side of the first outdoor valve and guiding the refrigerant to bypass the outdoor heat exchanger, so that the refrigerant can be guided to bypass the outdoor heat exchanger during defrosting operation of the cooling system.

Abstract: A cooling system and a control method thereof are provided. The cooling system may include a first compressor, a second compressor disposed downstream of the first compressor, an outdoor heat exchanger the performs heat exchange between refrigerant compressed in the first and/or second compressor and external air, an expansion device that decompresses the refrigerant condensed in the outdoor heat exchanger, a cooling evaporator evaporating the refrigerant decompressed in the expansion device, a bypass tube that guides refrigerant compressed in the first compressor to the outdoor heat exchanger, bypassing the second compressor, and a valve device controlling the flow of refrigerant discharged from the first compressor so as to selectively introduce refrigerant into the second compressor.
