Was sind R134a Anlagen?
Das Kältemittel R134a (Tetrafluorethan) ist nicht brennbar, nicht toxisch und farblos. R134a besitzt ein Treibhauspotenzial (Global Warming Potential, GWP) von mehr als 1 (GWP = 1430). R134a besitzt einen ODP – Wert (Ozone Depletion Potential) von 0.
Wie lange darf R134a verwendet werden?
Januar 2022 gewerblich genutzte Kühl- und Gefriergeräte mit dem Kältemittel R134a in den Verkehr zu bringen. Bis 2025 werden weitere Erzeugnisse, wie ortsfeste Kälteanlagen oder Mono-Splitklimageräte, mit besonders klimaschädlichen F-Gasen schrittweise vom Markt genommen.
What’s the difference between the R12 and the R134a?
The R134A as a replacement for R12. Soon, the R12 got banned in many places and were. As a result, replaced with other refrigerant gases out of which one is the R134A. Unlike the R12, the R134A contains hydrogen and fluorine molecules which is why it is known as HFC rather than CFC.
What is the weight of a molecule of R12?
Coming to its technical specs, the weight per molecule of R12 is about 121 with a boiling point of -21.6 degrees Fahrenheit. The molecules inside the R12 are of fluorine and chlorine which is why it is called chlorofluorocarbon or short for CFC, an abbreviation which has been very much standard in the 90s and earlier.
How to calculate the R12 charge on a car?
Take the R12 charge specification and multiply it by 0.9. Then, subtract that result by 0.25 pounds to get the proper amount of R134a charge. As an example, let’s say the R12 charge specification is listed at 2 lbs. You would do the following:
What happens if I Fill my compressor with R134A?
Just filling your compressor with the R134A would cause your compressor to work harder due to the higher pressure and eventually create a leak to seal. But that’s the second thing to worry about. The first thing is whether your factory compressor is good enough to work properly with the new R134A.
