WebIts ODP is zero but its GWP is rather high. Due to its low operating pressure (2-3 times lower than all other refrigerants), it's also used in large air-conditioning units with centrifugal compressors, but it's not suitable for industrial refrigeration systems due to poor efficiency at low temperatures. WebMar 13, 2024 · R-290 has excellent thermodynamic performance, it is energy efficient, and it is very reliable. Propane is very affordable and has ample supply especially when compared to some of the more expensive refrigerants out there like R-22. Cons The biggest drawback with propane, and with many other hydrocarbons, is flammability.

WebHFCs & Low GWP Refrigerants: Currently the major refrigerant is switching to Hydrofluorocarbons (HFCs) which has zero Ozone-Depletion Potential (zero-ODP). Even though HFCs have a zero-ODP, in some cases it has a Global Warming Potential (high-GWP). WebDec 13, 2024 · HFCs have no impact on the ozone layer (ODP = 0), while maintaining zero and low levels of flammability of synthetic refrigerants.
