Chlorodifluoromethane, also known as HCFC-22, is a colorless gas commonly used as a refrigerant in air conditioning and refrigeration systems. It has a low boiling point and is effective in heat transfer, making it suitable for cooling applications. This compound is part of the hydrochlorofluorocarbon family and was developed as a replacement for chlorofluorocarbons (CFCs), which are harmful to the ozone layer. However, chlorodifluoromethane is also being phased out due to its potential to contribute to global warming, leading to the search for more environmentally friendly alternatives.
