Background The core purpose of the fan structural design for the air source heat pump is to realize the conversion from low-level heat energy to high-level heat energy through the utilization of high-level energy, thereby achieving the energy-saving effect. The main components of the air source heat pump include an evaporator, a compressor, a condenser, an expansion valve, and a blower, which absorbs heat from the outdoor air and then transfers it to the room or other space to be heated. This is accomplished primarily by evaporation and condensation of the refrigerant in the system. Specifically, the refrigerant absorbs heat from the air in the evaporator and evaporates, then the refrigerant in vapor form is compressed by the compressor, raising its temperature and pressure, then releases heat in the condenser and condenses to a liquid, and finally reduces the pressure through the expansion valve, returning to the evaporator for continued circulation. The fan plays a vital role in the air source heat pump, and is mainly used for driving air flow, so that air can be subjected to heat exchange through the evaporator, the fan is generally arranged outdoors and is filled with a large amount of dust, the dust can greatly reduce the radiating effect of the radiating fins, increase noise and reduce the negative effect of air quantity, and meanwhile, the fan can vibrate during operation, thereby generating acoustic pollution and affecting the environment.
