Title:
HOT WATER STORAGE TYPE HEAT SOURCE DEVICE, AND OPERATIONAL METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2015075321
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hot water storage type heat source device constituted to comprise an electro-thermal cogeneration device, a heat pump device and a hot water storage tank and which can improve an operation efficiency better, and an operational method therefor.SOLUTION: A hot water storage type heat source device comprises a control part 50 for activating a heat pump device 20 to heat a second heat exchanger H2, circulating the hot water heated by the second heater exchanger H2 through a second circuit C2 and storing the hot water in a hot water storage tank 30. In the case where the calorie for one day from a hot water using place 40 is or expected to be higher than the exhaust heat amount for one day of an electro-thermal cogeneration device 10, the heat pump device 20 is activated to heat the second heat exchanger H2, while putting priority to the time band which is prior to the hot water supply from the hot water using place 40 and in which electric power load is or expected to be lower than the rating power generation output of the electro-thermal cogeneration device 10, and the hot water heated by the second heat exchanger H2 is circulated in the second circuit C2 and stored in the hot water storage tank 30.
