HEAT PUMP TYPE HOT WATER SUPPLY DEVICE AND METHOD OF STERILIZING HOT WATER

摘要

A heat pump type hot water supply device (1) having a hot water storage tank (1) and a hot water circulation circuit (50) is provided with a sterilizing component generator (60), such as an electric discharge device (65) for performing streamer discharge, in order to suppress occurrence of bacteria, such as legionnaire bacteria, at low cost.  The sterilizing component generator (60) generates a sterilizing component at a temperature lower than or equal to the temperature of hot water in the hot water circulation circuit (50).
