It's a greenhouse gas, though, and it doesn't work as well as R22. It has an ozone depletion rating of zero, and its global warming potential is 2100.

R-134a had the benefit of not containing Chlorine so with its usage there would be no danger to the Ozone layer.

Before 93 we used R-12 for our vehicles and now, as I write this article in 2018, there is a push to phase down R-134a and replace it with the new HFO refrigerant known as R-1234yf.This article is going to into the facts of R-134a, some of the most common questions asked about this refrigerant, and some of the most important points of note on the refrigerant, as well as the history of the refrigerant. Are all R134a refrigerant same quality? They had their hearts set on R-744 CO2.

For a time it seemed like German Automakers were going to fight HFOs tooth and nail. Never mix refrigerants and never use a refrigerant other than the type specified for your system. I mentioned this briefly above but R-134a was designed and began to see use as an alternative product to R-12 Freon, or Dichlorodifluoromethane. The scientists noticing this sounded the alarm and the world’s governments took action by creating the Montreal Protocol.The Montreal Protocol is a treaty that was signed in the late 1980’s by more then one-hundred countries. Even if we switch over our new vehicles today there will still be vehicles manufactured last year that will be on the road twenty or thirty years from now. R134a is a pure refrigerant that is sometimes used in blends, while R410a is itself a blend. By the time we got into the 1970’s the product was everywhere ranging from automobiles, refrigerators, freezers, ice machines, vending machines, industrial plants, refrigerated trucks, and on and on. Before these came to the marketplace the world only had access to basic refrigerants such as Hydrocarbons and Carbon Dioxide. Instead of pasting a large table of information here I will instead direct you to our specific refrigerant temperature page. A Greenhouse Gas is a gas that can be released and get trapped in the atmosphere. As time went by there were other CFC and HCFC refrigerants phased out but the big change didn’t happen until 2010.As I mentioned above 1993 was the beginning of R-134a usage. In the years following the switch to R134a, there was confusion over what was required to maintain the A/C of older cars. Europe switched over to 1234yf and the demand for R-134a began to die down. Can you begin to see why these are seen as a problem? In these instances you would either see a mixture of R-134a and R-404A or a straight R-404A system. CO2’s GWP is one.The downside of HFC refrigerants is their very high Global Warming Potential. The ASHRAE gave R410a a rating of A1 for safety. The video can be seen below. The first target was CFC refrigerants such as R-12. While 134a didn’t have near as high as a GWP of 404A it still had a large number coming in at one-thousand four-hundred and thirty.

The only exceptions that you would find were with refrigerated transport trucks such as ice cream trucks. At the same time, new regulations regarding recharging of the older air conditioning systems on classic cars were also mandated. Recharging your A/C system with refrigerant can be a simple fix.

Since then it has ballooned and grew so that every vehicle around the globe was using it. After all, there are still R-12 vehicles out there, right? The molecular weight of refrigerant R134a is 133.4 and its boiling point is -15.1 degree F. Refrigerant R134a is a hydrofluorocarbon (HFC) that has zero potential to cause the depletion of the ozone layer and very little greenhouse effect. The refrigerant R134a is the chemical compound tetrafluoroethane. This rule called ‘1234yf is the future and there isn’t much we can do to get away from it. These refrigerants are intended for different applications, but the proper use and handling of both are controlled by the Environmental Protection Agency.R134a refrigerant was developed to replace R12 in automotive air conditioning systems. Instead of refrigerants harming the Ozone layer the concern became the refrigerants impact on Global Warming. It has an ozone depletion rating of zero, and its global warming potential is 2100. Daimler claimed that the new refrigerant was unsafe for use. It isn't the only CFC alternative on the market, and it isn't the best. R-134a refrigerant is less efficient than R-22, but its ozone depletion potential is zero. Through this partnership the two companies were able to invent a safe, reliable, and cost efficient class of refrigerants known as CFCs and HCFCs.These new classifications of refrigerants were revolutionary. R134a has a boiling point of -14.9 degrees Fahrenheit, whereas R410 boils at -61.9 degrees. Some of these were R-404A and R-410A. A remodeling and repair specialist with over 20 years experience, he is also a Certified Pool Operator and holds an EPA Universal refrigerant certification. As an example, R-404A has a GWP of three-thousand nine-hundred and twenty-two times that of Carbon Dioxide.
