Title:
water supply -- warming -- a system
Document Type and Number:
Japanese Patent JP6249282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a refrigerant pressure on a discharge side from increasing excessively at start time of a compressor 13, in a water supply heating system 1 which performs adjustment of a water supply flow rate to a water supply tank 3 via a water supply passage 8 by opening adjustment of a water supply valve 10.SOLUTION: Water can be supplied to the water supply tank 3 by the water supply passage 8 via a condenser 14 of a heat pump 4. While supplying water to the water supply tank 3 via the water supply passage 8, an opening of the water supply valve 10 is adjusted so that detection temperature of a hot water tapping temperature sensor 29 is maintained at preset temperature, and the water supply flow rate to the water supply tank 3 is adjusted. When the water supply valve 10 is opened and the compressor 13 is started from a state in which the water supply valve 10 is closed and the compressor 13 is stopped, the preset temperature is decreased, the water supply valve 10 is fully opened or a supply flow rate of a heat source fluid to an evaporator 16 is limited.
