Tetrafluoroethane is a haloalkane refrigerant with thermodynamic properties and was used to replace dichlorofluoromethane (a colourless odourless gas that was used as a propellant and refrigerant) as it was found to be harmful to the environment – it contributed to ozone depletion. Tetrafluoroethane is now subject to restricted use as it has been discovered it also contributes toward climate change.
