Document Type and Number:
WIPO Patent Application WO/2018/079238
Kind Code:
A1
Abstract:
This refrigeration device is provided with: a heat exchanger (32) which condenses a refrigerant compressed in a compressor (31); a receiver (34) which separates, into a gas refrigerant (RG) and a liquid refrigerant (RL), the refrigerant condensed in an expansion valve (33) for expanding a refrigerant condensed in the heat exchanger (32); an injection circuit (38) which sends the gas refrigerant (RG) separated in the receiver (34) to the compressor (31); and a controller (100) which, in the case that a level sensor (342) detects that the level of the liquid refrigerant (RL) stored in the receiver (34) has reached a reference level, performs control so as to lower the rotation speed of the compressor (31).
