The systems use R32 as the refrigerant, which has a global warming potential (GWP) of 675, and rely on a "small-capacity, high-efficiency compressor" that can reportedly maintain efficient operation under low-load conditions, reducing the energy losses associated with frequent compressor cycling. ...Den vollständigen Artikel lesen ...
