Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/166806
Kind Code:
A1
Abstract:
The purpose of the present invention is to ensure reliability in a coolant compressor and an inverter, and efficient operation of a refrigeration cycle device. This refrigeration cycle device (1) is provided with: a refrigeration cycle in which a coolant compressor (2), a condenser (3), a first decompressor (4), and a first cooler (5) are connected; an inverter (6) for feeding AC power to a motor (24) of the coolant compressor; a bypass coolant pipe (7) branching from between the condenser and the first decompressor, the bypass coolant pipe (7) being linked between the first cooler and the coolant compressor; a second decompressor (8) disposed on the bypass coolant pipe; and a second cooler (9) disposed on the bypass coolant pipe on the outlet side of the second decompressor, the second cooler (9) cooling the inverter. A first control unit (300) controls the degree of superheat of the refrigeration cycle to a target-value range by adjusting the opening degree of the first decompressor, and controls the cooling temperature of the second cooler cycle to a target-value range by adjusting the degree of opening of the second decompressor.
