HOT WATER GENERATING DEVICE USING HEAT PUMP

摘要

PROBLEM TO BE SOLVED: To demonstrate sufficient hot water generation performance of a heat pump by preventing lowering of the temperature of a compressor. SOLUTION: When a heat pump 21 is worked, the temperature of raw water fed to a feed water pipe 10 is increased to generate hot water, while heat is being recovered from hot drain fed from dishwasher 1 to a hot drain recovery tank 30. The devices are contained in a casing 22 and the casing 22 is provided with a fan to discharge steam to the outside along with the feed of hot drain. The fan 62 is operated in synchronism a compressor 24. Cooling is prevented from occurring because the outside air makes contact with the compressor 24 due to the stop of drive of a fan for steam bleeding during the stop of the compressor 24, and when the heat pump 21 is worked followingly, sufficient hot water generation performance thereof is provided.
