Hydrofluorocarbon, chemicals used as refrigerants in automotive AC systems.
HFC-134a (1,1,1,2-tetrafluoroethane) is a specific type of refrigerant often referred to simply as R-134a. While both terms are commonly used interchangeably, "HFC-134a" emphasizes its classification as a hydrofluorocarbon (HFC), which is important for understanding its environmental impact and regulatory status. There are no significant differences in their chemical composition or application; both refer to the same refrigerant used primarily in automotive and refrigeration systems.

HFC Haarlem ended in 2010.
HFC Haarlem was created in 1889.
HFC-152a is a better replacement for CFCs compared to HFC-23 because it has lower ozone depletion potential and global warming potential. HFC-152a is used as a refrigerant and blowing agent in various applications due to its lower environmental impact compared to HFC-23.
HFC's will somewhat damage the ozone. But they will not damage as much as CFC's.

Hfc-134a is the refrigerant used in moble air conditioning systems (MVAC).
Yes, HFC-134a and 134a refer to the same chemical compound, which is 1,1,1,2-tetrafluoroethane. The "HFC" designation stands for hydrofluorocarbon, indicating its classification within that group of compounds. HFC-134a is commonly used as a refrigerant in air conditioning and refrigeration systems.
As of July 2014, the market cap for HollyFrontier Corporation (HFC) is $9,105,550,321.66.

The alternate refrigerant with a GWP rating of 4 that is replacing HFC-134a is HFO-1234yf. This hydrofluoroolefin is designed to have a much lower environmental impact compared to traditional HFCs, making it suitable for automotive and other cooling applications. Its low GWP helps in reducing the overall greenhouse gas emissions associated with refrigeration and air conditioning systems.
