Document Type and Number:
WIPO Patent Application WO/2022/180716
Kind Code:
A1
Abstract:
The heat supply system according to one aspect of the present invention comprises a cushion tank (2) provided to outward-path piping (11), a first heat source device (30) that has a vapor-compression heat pump (31) and that heats reserved water inside the cushion tank (2), a second heat source device (40) that has a combustion boiler (41) and that heats the reserved water inside the cushion tank (2), a return temperature detection means (91) that detects the return temperature Tr of circulating water that is sent back from a thermal load unit (14, 15) through return-path piping (13), a first control means (60) that controls the operation of the first heat source device (30) on the basis of the return temperature Tr, and a second control means (80) that controls the operation of the second heat source device (40) on the basis of the return temperature Tr.
