PURPOSE: A hybrid non-defrost heat pump is provided to use waste heat through a heat pump. CONSTITUTION: A hybrid non-defrost heat pump includes a compressor(16), an expansion valve(12), an outside air heat exchanger, a first water heat exchanger, an indoor air heat exchanger, a second water heat exchanger(22), a third water heat exchanger(24), a third water valve(50), a second water valve a fifth valve, a sixth water valve, a fourth valve, a first valve, and a seventh valve. The compressor insulates and compresses refrigerant. The expansion valve insulates and expands the refrigerant. The third water valve selectively connects the output of the first water heat exchanger and the input of the third water heat exchanger, and the first water heat exchanger and a hot water tank. The second water valve selectively connects the output of the third water heat exchanger and the input side of the first water heat exchanger, and the first water heat exchanger and a water supply source. The fifth valve selectively connects the input side of the second water heat exchanger and the first water vale, and the input side of the second water heat exchanger and the seventh valve. The sixth valve selectively connects the output side of the second water heater exchanger and the fourth water valve, and the output side of the second water heat exchanger and a second input side of a heating water buffer tank. The fourth valve selectively connects the hot water tank and the third water valve, and the hot water tank and the seventh valve. The first valve selectively connects the water supply source and the second valve, and the water supply source and the sixth water valve. The seventh valve selectively connects a heating pipe and a second input side of the heating water buffer tank, and the heating pipe and the fifth valve. |
