Title:
REFRIGERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/011845
Kind Code:
A1
Abstract:
This refrigerating device comprises: a main refrigerant circuit in which a compressor, a condenser, a throttling device, and an evaporator are connected via refrigerant piping; a first bypass circuit that returns refrigerant discharged from the compressor to the intake side of the compressor by causing the refrigerant to flow into the evaporator from one side of the evaporator connected to the throttling device; a second bypass circuit that returns refrigerant discharged from the compressor to the intake side of the compressor by causing the refrigerant to flow into the evaporator from the other side of the evaporator that is connected to the compressor; a bypass switching unit that switches the flow path of the refrigerant between the main refrigerant circuit, the first bypass circuit, and the second bypass circuit; and a control unit that switches the flow path of the refrigerant by controlling the bypass switching unit in accordance with the operation state.
