Q. What refrigerant gas is used most frequently?

Hydrofluorocarbons are the most widely used refrigerator gas worldwide (HFCs). Chlorofluorocarbons (CFCs) were previously more commonly utilized but have now been phased out due to the Montreal Protocol's implementation in 1987. Additionally R-32 is widely utilized and is an appealing reduced GWP option for air conditioning. The R-407C family of refrigerants based on blends of R-134a R-125 and R-32 has been introduced as reduced GWP alternatives to current products and are appropriate for use in refrigeration and air conditioning. R-134a is one of the most used refrigerants and may be found in a wide variety of automobile commercial and home air conditioning units globally.
