Title:
HOT WATER STORAGE-TYPE HOT WATER SUPPLY SYSTEM AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2012/004985
Kind Code:
A1
Abstract:
Disclosed is a hot water storage-type hot water supply system having a battery unit, a heat pump cycle, a water storage tank, a water circulation path, a first path, a second path, a first temperature detection unit, a second temperature detection unit, and a control unit. The heat pump cycle circulates a first refrigerant. The first path and the second path circulate a second refrigerant. The first temperature detection unit detects the temperature of the battery unit. The second temperature detection unit detects the temperature of water stored in the water storage tank. The control unit causes the second refrigerant to pass through the first path when the temperature of the battery unit, detected by the first temperature detection unit is higher than a first predetermined temperature. The control unit causes the second refrigerant to pass through the second path when the temperature of the battery unit, detected by the first temperature detection unit is lower than a second predetermined temperature. The control unit closes the first path and the second path when the temperature of the battery unit, detected by the first temperature detection unit is the second predetermined temperature or more and the first predetermined temperature or less.
