Title:
AIR-CONDITIONING SYSTEM AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/034021
Kind Code:
A1
Abstract:
This air-conditioning system (100) comprises a compressor (21), first heat exchangers (22, 23), a second heat exchanger (25), a first valve (241), a second valve (242), a refrigerant circuit (29), a heat source device (300), and a control device (20), and is configured so as to switch an air-conditioning operation mode between a first mode, in which a first heat source operation is carried out, and a second mode, in which a second heat source operation is carried out. The first heat source operation is an operation for driving the compressor (21) and thereby exchanging heat between an air-conditioned space and a refrigerant flowing in the first heat exchangers (22, 23), the second heat source operation is an operation for supplying heat generated by the heat source device (300) to the air-conditioned space, and the control device (20) reduces the degree of opening of the first valve (241) and the second valve (242) when the air-conditioning operation mode is switched from the first mode to the second mode.
