What is the difference between r134a and 134a

The refrigerant known in the industry as Ra came into use in the s as automakers, among others, sought a more environmentally safe way to provide cooling inside cars and trucks. Ironically, Ra now faces serious scrutiny as a culprit in global climate change, and as of , the European Union has banned its use in all new cars. Still, Ra ranks as more or less the industry standard for domestic and automotive cooling needs.

Some people use the terms R and Ra interchangeably, as seen in a casual search of automotive websites and storefronts, but they aren't identical. The same number and type of atoms make up R and Ra, but the arrangement differs. A refrigerant manufacturer told me that the automotive juice is not tested to the standards of purity and dryness that the refrigeration stuff is. In reality, I doubt that there would be a problem using the auto version for refrigeration systems.

The oil with Refrigerant adds up to a total weight of 1 lb per can. This was back when the R phase-out for automotive manufacturers and the RA retrofits were in full swing. The MACS study guide mandated separate equipment for each type of refrigerant used, such as gauge manifolds, hoses, recovery and recycle equipment. On-site recycling [not to be confused with Reclaiming] is common in automotive AC service shops and refrigerant that is recovered is routinely run through recycling equipment before being reintroduced back into the system.

You can even use it in place of RA. It is usually added in when the system is charged. Unlike R- a , HC- 12a is completely compatible with the hoses and oils used in R systems, making the conversion much easier to accomplish. Can I put one can of synthetic and one can of regular ra freon? ALL Ra is " synthetic ". There is no naturally occurring Ra. It's a very specific formulation. Brand shouldn't matter.

Ra is patened by dupont. Yes is the correct answer. Refrigerant, and in this case I am speaking specifically about Ra, but it's typical of refrigerant gases, is heavier than air. Always check with the refrigerant manufacturer, but the chemical composition of Ra is all the same regardless of the name on the canister.

Interdynamics Artic Automotive Refrigerant Ra. FJC Refrigerant. Is there a difference between a and ra? Category: home and garden indoor environmental quality.

Difference between Ra and a? It's the same most likely. What does the A stand for in a? Can I use automotive ra in a refrigerator? How much freon does a refrigerator hold?
