Description

Technical Field

[0001] The utility model relates to the technical field of air heat source pumps, in particular to an anti-frost air heat source pump. Background Art

[0002] Air heat source pump, also known as air source heat pump, is an energy-saving device that converts the heat contained in the air, soil or water that cannot be directly used into directly usable thermal energy. It can save coal, gas, oil, electricity and other energy sources.

[0003] When the air source heat pump is in use, first turn on the power, then use the fan to draw outside air into the air source heat pump, and exchange heat with the evaporator. The evaporant in the evaporator absorbs heat and vaporizes into the compressor. The compressor compresses the evaporant into high-temperature, high-pressure gas and sends it to the condenser. After the water enters the condenser, it absorbs the heat of the evaporant and is heated.

[0004] However, when the outside temperature is low, the surface temperature of the evaporator will be lower than 0℃, and frost will occur on the surface of the evaporator. If the frost layer is not removed in time, it will become thicker and thicker on the evaporator, resulting in a decrease in the heat exchange effect of the evaporator. Utility Model Content
