What Is The Benefits Of EVI Heating Technology?
There is no doubt that air source heat pumps can make great economic and environmental benefits if they are properly used. However, as a matter of fact, most air source heat pumps work with very poor efficiency or even can not work when the environment temperature is lower than -10℃.The EVI (enhanced vapor injection) heating technology is an innovation in the compressor and the refrigerant circulation. By this technology, the permitted operating range of a heat pump is extended to a much lower air temperature region, and the heating performance under low environment temperature is greatly improved.
