HEAT PUMP HOT WATER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an instantaneous water heater type heat pump hot water supply system having superior rising of a hot water supply temperature and controllability and capable of efficiently supplying the hot water.

SOLUTION: This instantaneous water heater type heat pump hot water supply system directly passes tap water to a water channel 12 of a heat exchanger 10 exchanging heat between a refrigerant channel a11 and the water channel 12 and uses hot water delivered from the channel. This device is so constituted as to have heating means 18 heating the water in previous/following routes including the water channel 12 of the heat exchanger 10, so that the rising of the hot water supply temperature in starting the hot water supply is quick and its controllability and the efficiency are favorable.
