Want this question answered?
r134
NO ! and Why?
No, the two cannot be blended.
No, the two cannot be blended.
the things that must be considered when charging the system with R22; R404;R134;R507;R406
if approved by the compressor manufacturer, then yes, if not, then no...
After 1992- r134A Before 1992- R22 but it need to be retrofitted for R134 if it hasn't been done already. It is ILLEGAL to use R22 in autos.
what will replace R 134 refrigerant
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
It is an alternative to mostly banned CFCs (most infamous of which is R22), and to be phased out in the future HFCs (R410a, R134 and similar). That being said the general consensus is that R600a (isobutane) requires compressors/systems specifically designed for it. The most suitable HC or natural refrigerant substitute for R22 is R290, which although shunned by the industry will perfectly replace it with an efficiency increase of about 20% without any retrofitting or other adjustments.
Not without conversion.
No.
