Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/042969
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises a compressor (11), a radiator (12, 12a), a decompressor (13, 15), an evaporator (14, 14a), a heat medium cooling evaporator (16), a device (26, 27) to be cooled, a detector (44, 45, 46, 47, 48, 49), and a control device (40). The heat medium cooling evaporator cools a cooling heat medium by performing heat exchange between the refrigerant decompressed by the decompressor and the cooling heat medium having a specific heat greater than air. The device to be cooled is cooled with the cooling heat medium which has undergone heat exchange with the refrigerant through the heat medium cooling evaporator. The detector detects an overcooled state in which the device to be cooled becomes a predetermined reference temperature or less. When the overcooled state of the device to be cooled is detected by the detector, the control device increases the degree of superheating of the refrigerant flowing out from the heat medium cooling evaporator relative to when the overcooled state of the device to be cooled is not detected.
