Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026766
Kind Code:
A1
Abstract:
Provided is an air-conditioning device with which the temperature of hot air can be adequately raised when a high-temperature air request for temporarily raising the temperature of hot air being discharged is received. A refrigerant circuit has a first refrigerant path in which a compressor, a first usage-side heat exchanger (121), a first expansion valve (131), and a heat-source side heat exchanger are connected in order. A control unit controls the compressor and the first expansion valve (131). When a high-temperature air request is received for temporarily raising the temperature of hot air that passes through the first usage-side heat exchanger (121) to be discharged, the control unit changes the control of the first expansion valve (131) so as to raise the temperature of the refrigerant flowing through the first usage-side heat exchanger (121).
