Description

Technical Field

[0001] The utility model relates to the technical field of air energy assistance, in particular to an air energy heat pump with a constant temperature function. Background Art

[0002] Air-source heat pumps use the heat in the air to generate thermal energy. They can provide the whole family with different hot water, heating and cooling needs with large water volume, high water pressure and constant temperature 24 hours a day, while consuming the least energy to meet the above requirements. After providing hot water, existing air-source heat pumps rely on insulation from water storage containers, and the insulation efficiency is low. There is a need for an air-source heat pump with a constant temperature function.

[0003] The existing announcement number is CN216716622U, and the patent is named "An Air Energy Heat Pump". The utility model provides an air energy heat pump. The utility model relates to the field of heat pump technology. The air energy heat pump includes a casing, a water tank, an air heat exchanger and a compressor. The water tank, the air heat exchanger and the compressor are all fixed in the casing. The water tank and the air heat exchanger are distributed on the left and right, and the compressor is located above the water tank and the air heat exchanger; a heat exchange component is wrapped around the outside of the water tank, and the heat exchange component can heat the water tank; two groups of positioning components are sleeved on the outside of the heat exchange component, and the two groups of positioning components are respectively installed on the front and rear sides of the water tank, so that the heat exchange component is positioned outside the water tank. The beneficial effect of the utility model is that the heat in the middle of the heat exchange tube can be quickly transferred to the heat exchange tube, the heat absorbed by the water tank can be maximized, and the air energy heat pump can be used more effectively. The heat exchange tube can be positioned, and the heat exchange capacity of the heat exchange tube can be indirectly improved, thereby accelerating the heating speed of the water tank.

[0004] The above device allows the heat in the middle of the heat exchange tube to be quickly transferred to the heat exchange tube, which can maximize the heat absorbed by the water tank, but the heat still needs to pass through the water tank wall to heat the water inside, and the heating efficiency is low. After the water in the water tank reaches a certain temperature, it is difficult to continue to heat up due to the heat conversion efficiency. The water in the water tank is difficult to maintain the temperature of normal water for use, and cannot meet people's usage needs well. In view of the above situation, technical innovation is carried out on the basis of the existing air energy heat pump. Utility Model Content
