Is R12 refrigerant explosive?

Is R12 refrigerant explosive?

Refrigerant R12 is used in domestic refrigerators and freezers, liquid chillers, dehumidifiers, ice makers, water coolers, water fountains and transport refrigeration. R12 is non-toxic, non-flammable, and non-explosive. This makes it highly popular for the domestic as well as the commercial applications.

Are R12 and R134 fittings different?

R134a service fittings are totally different than R12 fittings. The R134a fittings are larger than R12 fittings.

Why is R12 bad?

It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable. Unfortunately, the widespread use of R12 appeared to be significantly degrading the Earth’s ozone layer, potentially causing a worldwide health crisis.

What’s the difference between R-12 and R-134a?

Regardless of which retrofit method is used, cooling performance will vary depending on the design of the system. As a rule, expect anywhere from a 3% to 15% decrease in cooling performance when an R-12 system is converted to R-134a.

Can You retrofit a car to use R-134a refrigerant?

There is NO reason to retrofit a vehicle to R-134a as long as the R-12 system is cooling properly and contains a normal charge of refrigerant. A/C systems designed to use R-12 will cool best when charged with R-12 refrigerant. Even if the system leaks, repairing the leaks and recharging it with R-12 is usually the best repair alternative.

Is the Harrison DA6 compressor compatible with R-134a?

Compressor durability can be a concern on some older applications. Because R-134a raises compressor discharge pressures and increases the compressors work load, some lightweight compressors may not be rugged enough to tolerate R-134a over the long haul. This applies to the Harrison DA6 and Ford FX-15 compressors.

Is it possible to retrofit an R-12 a / C system?

The other approach to retrofit is the “quick and cheap” one. On many 1989 through 1993 vintage vehicles, R-12 A/C systems can be converted by simply recovering any refrigerant that is still in the system, adding POE oil (which is compatible with both types of refrigerant), and recharging to 85 to 90% capacity with R-134a.

How to add refrigerant to a 1995 Chevy Cavalier?

What’s the difference between R12 and R134a air conditioners?

However, there were—and are—some challenges to using it in an automotive A/C system designed for R12. The molecule size of R134a is smaller than that of R12, so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used.

What are common reasons my Chevrolet Cavalier has air conditioning problems?

What are common reasons my Chevrolet Cavalier has air conditioning problems? While there are a variety of reasons your Chevrolet Cavalier air conditioning won’t work, the most common 3 are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.
