Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/126059
Kind Code:
A1
Abstract:
This air-conditioning device transmits to a three-way valve (20) a first selection signal for selecting a heating unit (305), if a heating operation mode using the heating unit (305) is designated and there is no hot-water supply request for using the hot water in a hot-water tank (19). If the heating operation mode is designated and a hot-water supply request is generated, the air-conditioning device transmits an operation start signal to a refrigerant indoor unit (303) while transmitting to the three-way valve (20) a second selection signal for changing an object through which a secondary refrigerant is to be circulated, from the heating unit (305) to a coil heat exchanger (18).
