R-134a, known as 1,1,1,2-Tetrafluoroethane, is a widely used refrigerant with applications primarily in automotive air conditioning systems. This gas provides efficient cooling in a range of environments, including:

• Automotive Air Conditioning: R-134a is the standard refrigerant in most vehicle air conditioning systems, ensuring comfortable temperatures during hot weather.
• Residential Air Conditioning: Some home air conditioners also utilize R-134a to maintain indoor comfort for families and individuals.
• Commercial Refrigeration: In addition to cars, R-134a is used in various commercial refrigeration applications like walk-in coolers and freezers.

Environmental impact:

• R-134a has a relatively lower GWP compared to some other refrigerants, making it a preferred choice for certain applications. However, it is still being phased out in some regions in favor of even lower-GWP alternatives like R-1234yf.
