Refrigeration cycle device

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.

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2018-166947 filed on September 6, 2018, the contents of which are cited here. technical field [0003] The invention relates to a refrigeration cycle device applied to an air conditioner. Background technique [0004] Conventionally, the technology described in Patent Document 1 is known as a refrigeration cycle device applied to an air conditioner. The refrigeration cycle device described in Patent Document 1 is applied to an air conditioner and is configured to be capable of cooling a secondary battery as a temperature adjustment object. [0005] The refrigeration cycle device of Patent Document 1 includes: a heating unit that uses high-pressure refrigerant discharged from a compressor as a heat source to heat blown air blown into a space to be air-conditioned; an indoor evaporator that cools the blown air by evaporating the low-pressure refrigerant; Cooli...

AI Technical Summary

Problems solved by technology

[0012] In this regard, although the refrigeration cycle device described in Patent Document 1 can cool the secondary battery through the cooling unit, it cannot warm up the secondary battery.

Therefore, in the refrigeration cycle device disclosed in Patent Document 1, there is a possibility that the temperature of the secondary battery, which is the subject of temperature adjustment, cannot be appropriately adjusted.
