Is hfc134a the same as R134a?

R134A or HFC-134A became the accepted standard, because it has no potential of ozone depletion and has similar (but not equal to) cooling abilities to the R-12 and R-22 refrigerants. Computer air has fewer lubricants in it than the conventional R134A.

Is R134a an HFC?

R134a is a HFC, used in automotive air conditioning and as a replacement for R12 and R22 in medium and high temperature refrigeration applications, such as commercial and domestic refrigeration and chillers. R-134a is an HFC refrigerant, which requires polyolester (POE) lubricant to be used in the compressor.

What is R134a refrigerant formula?

Thermodynamic properties of refrigerant R-134a is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential. R-134a has the formula CH2FCF3.

What is the other name for refrigerant R134a?

1,1,1,2-Tetrafluoroethane

Can you put R134a in an R22 system?

Using R134a in Systems Designed for R22 If you have a home or auto air conditioner designed to work with R22 refrigerant, and the system needs a recharge, a number of issues prevent the direct substitution of R134a. R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger.

What refrigerant can be mixed with R22?

The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined with the remaining R-22 in the system, said Maiorana.

Why R134a is not used in AC?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. In addition, there was the lubricant issue. Because A/C compressors have moving parts, they require oil.

What makes R134a a good refrigerant?

R134a has fairly good dielectric properties as it has high thermal stability, low boiling point, and chemical inertness against the construction materials used; and is non-toxic and non-flammable. . A dielectric substance in its gaseous state can be used to prevent electric discharges.

Is R134a banned?

On September 26, 2016, the EPA announced that, under the EPA SNAP (Significant New Alternatives Policy) program, specific refrigerants including R134a and R410A can no longer be used in new chillers, effective January 1, 2024.

Can I use R22 in a R134a system?

R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger. R22 refrigerant and its HFC replacement R410A are totally incompatible.

What are the advantages of R134a over R12?

Chemistry. R12 is dichlorodifluoromethane (CCl₂F₂) and is classified as a chlorofluorocarbon (CFC).

What are the dangers of R134?

Inhalation of Vapor. Problems from inhalation of R134a depend on the dose; small amounts will not harm the lungs.

What can R134a be use for?

The refrigerant R134A is called tetrafluoroethane and is classified as one of the HFC gases from the other refrigerant variants. Today, R134A is commonly used in vehicle air conditioning systems, but it can also be used in refrigerators, freezers and other refrigeration equipment similar to R12.

Is R-134a a low pressure refrigerant?

As a low-pressure refrigerant system, the R134a is used in most home refrigerators as it is very effective and convenient for high-temperature applications. The R134a is a popular refrigerant used in a variety of modern refrigeration and air conditioning applications. Most refrigerators built after 1995 typically uses the R134a refrigerant.
