What is the formula for refrigerant?

The formula for refrigerants varies depending on the specific type used, as there are many different refrigerants with distinct chemical compositions. Common refrigerants include hydrofluorocarbons (HFCs) like R-134a (C2H2F4) and R-410A (a blend of HFC-32 and HFC-125). Other types, such as hydrochlorofluorocarbons (HCFCs) or natural refrigerants like ammonia (NH3) and carbon dioxide (CO2), also have their own formulas. Each refrigerant is designed to meet specific thermodynamic and environmental requirements.
