Description

Technical Field

[0001] The utility model relates to the technical field of air energy heat pumps, in particular to an evaporator with a defrosting function and an air energy heat pump. Background Art

[0002] An air-to-energy heat pump is a device that uses the heat energy in the air for heating and cooling, and realizes a thermodynamic cycle through key components such as an evaporator, a compressor, a condenser, and an expansion valve. The evaporator absorbs heat from the outdoor air, the refrigerant evaporates and the temperature rises; the compressor compresses the low-temperature, low-pressure steam into a high-temperature, high-pressure gas; the condenser releases heat and cools the high-pressure gas into a high-pressure liquid; the expansion valve relaxes the high-pressure liquid into a low-pressure liquid to complete the cycle. In actual operation, the evaporator part absorbs heat from the outdoor air during winter heating, and the moisture contained in the outdoor air condenses into frost when the surface of the evaporator is cold. If the frost layer is too thick, it will have an adverse effect on the normal operation of the equipment, so a defrosting operation is required. In the prior art, the defrosting of air-to-energy heat pumps is mostly started when the evaporator surface has been frosted. This method is likely to cause damage to the evaporator and seriously shorten the service life of the evaporator. In addition, the energy used for defrosting is usually electric energy, which is not conducive to energy conservation. Utility Model Content

[0032] When using the utility model, when the ambient temperature is normal, the air energy heat pump absorbs energy in the air and converts it in a normal state; when the ambient temperature is below zero degrees Celsius, the temperature sensor 6 detects that the temperature is lower than the set value, and transmits an electrical signal to the controller 5. The controller 5 controls the heating component 3 to transfer the temperature to the heat dissipation fins 2, thereby increasing the surface temperature and preventing frost. The photovoltaic component 4 can provide part of the energy for the heating component 3, and the remaining energy is directly provided by electric energy, which can effectively save part of the energy loss, and is economical and environmentally friendly.
