Title:
HEAT PUMP TYPE WATER HEATER
Document Type and Number:
Japanese Patent JP2013137169
Kind Code:
A
Abstract:
To suppress degradation of COP, and to shorten a time to stabilize hot water tapping temperature from starting, when an outside air temperature is low.
A heat pump type water heater includes a refrigerant circuit constituted by successively connecting a compressor, a water heat exchanger for heating hot water, an electric-operated valve, and an air heat exchanger, and a hot water supply circuit constituted by successively connecting the water heat exchanger, a tank, and a pump for supplying hot water from the tank to the water heat exchanger. In starting under a condition that the outside air temperature is a prescribed temperature or lower, the electric-operated valve is controlled on the basis of a target hot water tapping temperature.
