Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to an improved air energy heat pump. Background Art

[0002] An air-to-air heat pump is a device that uses the heat in the air to generate thermal energy. It includes a heat exchange mechanism, an expansion valve, a compressor and an evaporator. The air-to-air heat pump works according to the reverse Carnot cycle principle, that is, the compressor compresses the refrigerant to form a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the heat exchanger, and the high-temperature gas transfers heat with the cold water in the pipe of the heat exchange mechanism. The cold water absorbs the heat and becomes hot water. The high-temperature gas whose heat is taken away gradually converts into a gas-liquid state at room temperature. Subsequently, the gas-liquid refrigerant is sent into the evaporator through the throttling device, and the heat in the air is continuously input by a fan. The refrigerant is rapidly vaporized, and after absorbing the heat, it becomes a low-temperature and low-pressure gaseous refrigerant and is sucked into the compressor again.

[0003] During the long-term use of the air-to-energy heat pump, dust in the air will continuously enter the shell and be adsorbed on the blades of the intake fan, affecting the normal air intake work of the intake fan. Subsequent cleaning is also more troublesome, which greatly reduces the air conversion rate of the air-to-energy heat pump and reduces the service life of the air-to-energy heat pump.
