Problems solved by technology
At present, traditional heat pumps simply exchange heat through heat conduction between the refrigerant and the air. Since the heat contained in a unit of air is low, a large amount of air is needed to meet the heat absorption demand of the refrigerant, which leads to the fan at the evaporator The load is huge, and it is in the state of high-power operation for a long time, which is not only not conducive to energy saving and environmental protection, but also produces huge noise, and has the adverse effect of reducing the service life of the equipment

Embodiment Construction
[0026] Such as Figure 1-7 As shown, a high-efficiency and energy-saving air source heat pump heating device includes a compressor, an indoor heat exchanger, an expansion valve and an evaporator that are sequentially connected to form a heating cycle. The compressor is used to compress the refrigerant and convert the returning low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant. The indoor heat exchanger exchanges heat with the hot end of the water tank and air-conditioning cabinet. The expansion valve is used to throttle the condensed refrigerant and gasify it. , The evaporator is used as a place for heat exchange between the refrigerant and the air.
[0027] Compared with the traditional heat pump, the present invention has a huge difference in the heat exchange mode of the evaporator. Firstly, the evaporator includes a cuboid shell, and the upper and lower parts of the shell are provided with horizontal partitions 1 , the part...

Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to an air source heat pump heating device with high efficiency and energy saving. Background technique [0002] A heat pump is a heating device that uses the reverse Carnot principle to collect heat from low-temperature objects and transfer it to heat-consuming equipment through a medium. To put it simply, a heat pump mainly includes a compressor, an indoor heat exchanger, an expansion valve and an evaporator. The gas flows through the indoor heat exchanger and exchanges heat with the heat-consuming equipment. The cooled refrigerant becomes liquid under the continuous action of pressure, and enters the evaporator after passing through the expansion valve. Because the pressure of the evaporator suddenly drops, the liquid refrigerant Here it quickly evaporates into a low-temperature gaseous state, and exchanges heat with the air to absorb the heat in the air. Then the refrigerant...
