According to the current standard, the heating energy efficiency is required to be more than or equal to 2.4 at the ambient temperature of-12 ℃; the heating energy efficiency COP at minus 20 ℃ is more than or equal to 2.0. The traditional air conditioner aims at refrigeration, has a heating function and cannot meet the standard requirement.
In addition, the heat pump air heater applies an air-supplying enthalpy-increasing technology in design, adopts a compressor with air-injection enthalpy-increasing or secondary compression, and can improve the heating performance of the system at lower ambient temperature. The ultra-low temperature air source heat pump air heater is suitable for the ultra-low temperature environment in northern areas, and the conventional air source heat pump air heater can adapt to the environment temperature of summer hot and winter cold areas in Yangtze river basin, so that the application area is wide and the performance is high.
