Which is better R-32 or R-410A?
R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate.
When did HFC refrigerants become popular?
HFC refrigerants first started becoming popular and widespread in the early 1990’s. This came about due to the implementation of the Montreal Protocol.
What is a HFC?
HFCs, or HydroFluroCarbons, are a commonly used refrigerant classification used across the globe. Some of the most common HFC refrigerants that you may have heard of are R-134a, R-404A, R-410A, R-125, and R-32. These refrigerants are used in a variety of applications from automotive, to home air conditioners, all the way to industrial refrigeration.
What refrigerant was used in the 1990s?
The more Chlorine that was released the faster the damage occurred. There was an immediate push from various countries to phase out CFC and HCFC refrigerants. The first target was R-12 in the early 1990’s. R-12 was majorly found in car air conditioners and it was replaced by the HFC refrigerant known as R-134a.
What refrigerant replaces R-12?
R-12 was majorly found in car air conditioners and it was replaced by the HFC refrigerant known as R-134a. Not too many years afterward R-404A began to see popularity after replacing R-502 and recently in 2010 R-22 was phased down and intended to be replaced by the HFC R-410A.
Is HFC refrigerant going to be around?
In the United States HFC refrigerants are going to be around for quite a while. The transition away from them is going to be a long and slow process. We are already beginning to see some signs of with automotive manufacturers voluntarily moving away from R-134a and opting for the HFO 1234yf. On top of that some states have announced they will be doing a full phase down and phase out of HFCs. (California and New York.) There are more states expected to announce similar plans.

Is HFC a sustainable refrigerant?
While HFCs saved the Ozone layer we now understand that they are not a sustainable alternative refrigerant due to their high GWP. The push is on now to begin phasing down or completely phasing out HFC refrigerants for lower GWP/Non Ozone depleting alternatives.

What are hydrocarbons made of?
About Hydrocarbons. Hydrocarbons are naturally occurring chemicals made only from hydrogen and carbon. A blend of hydrocarbon with any other type of refrigerant would be considered the other type of refrigerant (CFC, HCFC, HFC, or HFO).
What are the different types of refrigerants?
These include CFC, HCFC, and HFC refrigerants.
How to minimize the environmental impact of refrigerant?
If you’re wondering how to minimize the environmental impact of refrigerants, it starts with tracking all your HVAC/R activity at all times , closely monitoring refrigerant usage, and reducing leak rates. 👍
