The invention relates to a double-source heat pump water heater, which is provided with different refrigerant circuit systems with three four-way valves and one four-way valve; the refrigerant circuit system with three four-way valves is characterized in that a first interface, a second interface, a third interface and a fourth interface of a first four-way valve are respectively connected with an exhaust port of a compressor, an inlet of a hot water heat exchanger, a third interface of a third four-way valve and an inlet of an air-liquid separator; an outlet of the hot water heat exchanger is connected with an inlet of a throttling device; a first interface, a second interface, a third interface and a fourth interface of a second four-way valve are respectively connected with an outlet of the throttling device, a lower end port of an air source heat exchanger, a lower end port of a water source heat exchanger and a first interface of the third four-way valve; a second interface and a fourth interface of the third four-way valve are respectively connected with an upper end port of the water source heat exchanger and an inlet of the air-liquid separator; an outlet of the air-liquid separator is connected with an air inlet of the compressor; a unit is provided with an air source, a water source, an air source and water source serial-connection circulation and defrosting plus antifreezing mode; and the heat cascade application double-source heat pump water heater is additionally provided with a heat recovery-clean water preheater, the coefficient of performance (COP) of the unit is higher than 6, and the double-source heat pump water heater is a high-efficient energy-saving product.

Description

Technical field: [0001] The invention relates to the technical field of heat pump water heaters. Background technique: [0002] Bathhouses, hotels, etc. need a lot of hot water, use gas, fuel oil, and electric heating, which wastes the precious quality of these energy, and the cost is also high; using a heat pump water heater can obtain 3 to 4 times the heat pump power consumption. Hot water, energy saving effect is obvious. In many occasions, there is a large amount of industrial or domestic hot water or ground source hot water whose temperature is higher than the ambient temperature. The heat source of the water source heat pump is used to produce domestic hot water at 55°C. However, the flow of waste hot water for bathing is unstable, and the hot water discharged from industry will also disappear from time to time. The single use of water source heat pumps cannot provide enough hot water for bathing. Therefore, air source heat pumps must be used as supplements. If a si...
