International Column: Propane Replacing R-22

Todays refrigeration systems consume around 15% of the worlds available electrical energy. Reducing their energy demand would make an important contribution to reducing the threat of global warming. Hydrocarbons such as propane, propene and isobutane have outstanding thermodynamic properties; refrigerating and air-conditioning systems that run on these refrigerants are particularly energy-efficient.
