However the power consumption is barely a part of the issue. The refrigerants utilized in air-con models are potent greenhouse gases. These refrigerants, particularly hydrofluorocarbons (HFCs), have a far increased world warming potential than carbon dioxide. The truth is, some HFCs are lots of to 1000’s of occasions extra highly effective at trapping warmth within the ambiance than carbon dioxide. When air conditioners leak refrigerant throughout their operation or when they’re disposed of improperly, these gases escape into the ambiance, contributing on to world warming.
Within the Eighties, CFCs (chlorofluorocarbons) had been the refrigerants of alternative, however they had been discovered to deplete the ozone layer, resulting in their eventual phase-out below the Montreal Protocol. They had been changed with HFCs, which, whereas much less dangerous to the ozone layer, are nonetheless potent greenhouse gases. The rise in HFC emissions is a serious concern, as they’re now the fastest-growing supply of greenhouse fuel emissions on the planet.
Trying to find Options: New Refrigerants and Power-Environment friendly Cooling Programs
