The invention discloses a split type water pump for preparing hot water by utilizing wind source waste heat. The split type water pump comprises a compressor, a four-way valve, a throttling and pressure-reducing valve, a hot water heat exchanger, a waste heat recycling heat exchanger, an outer evaporator, a two-way solenoid and a controller, wherein the output end of the compressor is connected with a tube d of the four-way valve; a tube c of the four-way valve is connected with the inlet of the hot water heat exchanger; after being in series connected with the throttling and pressure-reducing valve, the outlet of the hot water heat exchanger is divided into two paths which are connected with the inlet of the waste heat recycling heat exchanger and the inlet of the outer evaporator after being in series connected with the two-way solenoid respectively; the outlet of the waste heat recycling heat exchanger is connected with the input end of the compressor; the output port of the outer evaporator is connected with a tube e of the four-way valve; a tube s of the four-way valve is connected with the input end of the compressor; a waste heat recycling water outlet and a waste heat recycling water outlet are connected with a waste heat water tank; and a temperature sensor I is arranged on the outer evaporator. The split type water pump is simple in structure principle, and convenient to mount and maintain, so that heat exchange can be guaranteed to be carried out by utilizing waste heat of warm wastewater and the like when an outdoor temperature is relatively low, and extra energy is not required.
Description
technical field [0001] The invention relates to a split type air source waste heat hot water pump. Background technique [0002] Air source heat pump water heater is also called heat pump water heater. The heat pump absorbs the air heat source to produce hot water. The energy saving efficiency is more than 4 times that of the electric water heater. It is currently the most advanced energy saving and environmental protection hot water system in the world. The hot water produced can be used for heating or domestic water. The heat pump uses the reverse Carnot principle to absorb a large amount of low-temperature heat energy in the air with very little electric energy, which is compressed by the compressor and converted into high-temperature heat energy, which is transmitted to the water tank to heat hot water, so it has low energy consumption, high efficiency and fast speed , good safety, strong environmental protection, continuous supply of hot water. [0003] But when in us...
