HEAT PUMP HOT-WATER SUPPLY SYSTEM

摘要

A heat pump hot-water supply system is provided with a heat pump hot-water supply device, a hot-water storage tank which stores the hot water obtained by operating the heat pump hot-water supply device, and a control device which controls the start and stop of the heat pump hot-water supply device. The control device estimates the outside air temperature in the place in which the heat pump hot-water supply device is installed and determines the time of day of the operation of the heat pump hot-water supply device on the basis of the estimated value of the outside air temperature.
