R600a is a new hydrocarbon refrigerant with excellent performance. It is derived from natural ingredients, does not damage the ozone layer, has no greenhouse effect, and is green and environmentally friendly. It is characterized by high latent heat of evaporation and strong cooling capacity; good flow performance, low delivery pressure, low power consumption, and slow load temperature recovery. Compatible with various compressor lubricants. (Note: When R600a is insufficient in the refrigeration system, it will cause excessive pressure, abnormal machine sound, and shortened compressor life). R600a is a colorless gas at room temperature and a colorless and transparent liquid under its own pressure. It is a substitute for R12.
R600a refrigerant has high latent heat of evaporation and strong cooling capacity; good flow performance, low delivery pressure, low power consumption, and slow load temperature recovery. R600a refrigerant is compatible with a variety of compressor oils. Mainly used as ultra-low temperature refrigerant, andR22The composed refrigeration system is used for ultra-low temperature refrigeration devices at-80~-120℃. It is also used as a blowing agent for foam plastics and as a refrigerant replacementR12。
