The air-jet enthalpy increasing compressor of the low ambient temperature air source heat pump has one more air supplement port than the ordinary heat pump hot water compressor. When the steam generated by the evaporator is supplemented from the compressor shell to the compressor cavity, the exhaust temperature of the compressor is reduced, the length of the heat exchange zone of the heat pump heat exchanger is reduced, the two-phase heat exchange area is increased, and the heat exchange efficiency is improved.
At the same time, the air-jet enthalpy increasing system not only produces air supplement, but also increases the undercooling degree of the refrigerant before throttling, and increases the heat absorbed by the refrigerant in the evaporator, so as to improve the heating effect and ensure that a large amount of heat can even meet the needs of low-temperature environment.

The low-temperature air energy heat pump can still operate stably under the working condition of – 25 degrees, which greatly improves the application range of the heat pump, so that the thermal efficiency of the ordinary heat pump is greatly reduced within the temperature range of – 10 degrees. If it operates for a long time, the main engine of the air energy heat pump will heat up. Therefore, if you want to use the ultra-low-temperature air energy heat pump heating system in the low-temperature environment, Low temperature air energy heat pump is recommended.
