generally utilised refrigerants in houses and enterprises contain ozone-depleting refrigerants, and blends consisting totally or mostly of hydrofluorocarbons (HFCs). both of those HCFCs and HFCs are strong greenhouse gases. lately there have been numerous progress in air-con and refrigeration engineering which will help residences and enterprises reduce both of those refrigerant charges and refrigerant emissions.
