Description

Technical Field

[0001] The utility model relates to the technical field of air energy heat pumps, in particular to an air energy heat pump structure which is convenient for defrosting and draining water. Background Art

[0002] An air energy heat pump is a device that uses the heat in the air for heating or cooling. Its working principle is based on the principle of heat energy exchange in thermodynamics. The main components of an air energy heat pump include a compressor, an evaporator, a condenser, and a throttling device. Its working process is as follows: the refrigerant is in a low-pressure state and enters the evaporator through a diffusion valve. The air outside the evaporator passes through the evaporator, contacts the refrigerant, and exchanges heat. The heat in the air is absorbed and transferred to the refrigerant, causing it to evaporate and convert into a low-temperature, low-pressure gas; the low-temperature, low-pressure gas passes through the evaporator and enters the compressor. Inside the compressor, the gas is compressed into a high-temperature, high-pressure gas; the high-temperature, high-pressure gas leaves the compressor and enters the condenser, where the refrigerant exchanges heat with the water or air in the heating system. The refrigerant in the condenser releases heat, causing it to condense into a high-temperature, high-pressure liquid state; the high-temperature, high-pressure liquid passes through the throttling device, the pressure is reduced, and the temperature also drops, and it re-enters the evaporator for circulation. By continuously circulating this process, the air energy heat pump can extract heat from the low-temperature environment outdoors, transfer it to the heating system through compression and heat exchange, and realize the indoor heating function. In cooling mode, the air energy heat pump will transfer indoor heat to outdoor air through a similar principle to achieve cooling of the indoor space.

[0003] When the air-to-air heat pump works in a low-temperature environment, a large amount of frost will be generated around the evaporator due to the temperature difference between the inside and outside of the evaporator. It needs to be cleaned in time, otherwise it will affect the working efficiency of the evaporator. The existing air-to-air heat pump melts and cleans the frost around the evaporator through the work of the internal structure. The melted water directly falls around the heat pump. It is difficult for the water to evaporate in a low-temperature environment, which makes it easy for water to freeze around the heat pump, affecting the operation. In addition, when the heat pump cannot work, the frost on the outside is difficult to clean. Therefore, an air-to-air heat pump structure that is convenient for defrosting and drainage is needed.
