Document Type and Number:
WIPO Patent Application WO/2022/259287
Kind Code:
A1
Abstract:
This refrigeration device comprises: a main circuit in which a compressor, a condenser, a receiver, a first opening/closing valve, an expansion mechanism, an evaporator, and an accumulator are sequentially connected by refrigerant piping, the main circuit serving as a refrigerant circuit through which a refrigerant circulates; an evaporation mechanism that evaporates a liquid refrigerant stored inside the accumulator after a pre-cooling operation performed in order to cool the evaporator, or that evaporates a liquid refrigerant flowing through the refrigerant piping on the intake side of the accumulator during the pre-cooling operation in order to cool the evaporator; and a control unit that controls the main circuit and the evaporation mechanism.
