REFRIGERATION CYCLE DEVICE

Title:

REFRIGERATION CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/050040

Kind Code:

A1

Abstract:

This refrigeration cycle device (10) has a compressor (11), an outdoor heat exchanger (16), a decompression section (14b) for room cooling, an evaporator (18), a branch section (13e), a decompression section (14c) for cooling, a temperature regulation section (50), a confluence section (13f), a bypass passage (22a), and a first opening and closing valve (15a). The temperature regulation section (50) has a heat exchanger (19) for temperature regulation and regulates, using as the heat source a refrigerant flowing through the heat exchanger for temperature regulation, the temperature of an object (80), the temperature of which is to be regulated. In a room cooling/cooling mode for cooling blown air and the object, the temperature of which is to be regulated, the outdoor heat exchanger (16) is caused to function as a heat dissipater, and the evaporator (18) and the heat exchanger (19) for temperature regulation are caused to function as heat absorbers. In an object heating mode for heating the object, the temperature of which is to be regulated, a discharged refrigerant having been discharged from the compressor (11) is conducted through the bypass passage (22a) to the heat exchanger (19) for temperature regulation, and the object (80), the temperature of which is to be regulated, is heated using as the heat source the heat of the discharged refrigerant.
