Title:
HEAT PUMP HOT-WATER SUPPLY MACHINE WITH SOLAR SYSTEM
Document Type and Number:
Japanese Patent JP3846385
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat pump hot-water supply machine with a solar system capable of effectively utilizing energy and being easily controlled and having a simple structure.
SOLUTION: This hot-water supply machine has the solar system 3 provided with a collector 1 and a heat exchanger 2, a heat pump unit 4, and a hot-water storage tank 5. The hot-water storage tank 5 is provided with a high temperature water reflux port 7 from the heat pump unit 4 in an uppermost part 6 and the heat exchanger 2 in a lowermost part 8. It has a water feeding port 10 for the heat pump unit 4 in an intermediate part 9 of the hot-water storage tank 5 and a temperature sensor 11 in its vicinity. When the heat pump unit 4 is operated and the temperature sensor 11 detects water temperature higher than set temperature, operation of the heat pump unit 4 is stopped. Consequently, operation of the heat pump unit 4 can be controlled by a simple configuration, control of the whole system becomes easy, and use of inexpensive midnight electric power by a heat pump and effective use of solar heat energy can be achieved.
