R600a Isobutene Refrigerant – The Nature Friendly Way
Isobutane (R600a) is a naturally occurring refrigerant. Isobutane (R600a) and CO2 are the two mostly discussed and researched refrigerants for the future. And both with low global warming potential and ozone depletion potential are excellent refrigerants for a nature friendly refrigeration and air-conditioning. But with research on carbon dioxide cycles are still in a premature stage, R600a cycles can use current vapor compression systems with little design tweaking. Recent concerns with depletion of the ozone layer by freon gases (R12, R134a) have led to increased use of isobutane (R600a) as a gas for refrigeration systems, especially in domestic refrigerators and freezers.
