Document Type and Number:
WIPO Patent Application WO/2020/040471
Kind Code:
A1
Abstract:
A freezer is disclosed. A freezer according to an embodiment comprises: a compressor configured to discharge a refrigerant in the gas state; a condenser configured to cool and liquefy the refrigerant discharged from the compressor; a liquid-gas separator configured to primarily expand the refrigerant liquefied in the condenser to an intermediate pressure to collect the refrigerant in the liquid state and the gas state; and an evaporator which cools a predetermined space as the refrigerant in the liquid state flows from the liquid-gas separator into the evaporator and then is secondarily expanded to a final pressure and thus absorbs heat and is gasified, and which guides the refrigerant in the gas state in the liquid-gas separator to the compressor.
