I suppose the common auto refrigerant in Europe is R-134a, correct? Our United states of america spec 2004 V70 and 2007 XC90 use R-134a. Personally, I no longer mess with my auto a/c units. I take it to the pro's who have the approved equipment to control belch of freon refrigerant.
When full, the refrigerant dispensing can has a much college pressure than the low side of a running auto a/c. In that location is liquid freon in the can and gaseous freon above it. So to accuse into the low side without slamming liquid into the compressor one keeps the can upright.
As charging proceeds the dispensing can gets common cold and the pressure inside drops. To restore pressure level and speed up charging ane can put the can in a container of warm water (not hot).
In the bad onetime days (short on money and insufficiently concerned about the surroundings) I used to recharge my auto a/c'due south with the R-12 freon used at the fourth dimension. R-12 was an efficient refrigerant and liquified at a relatively depression force per unit area allowing a cheaper compressor. Just R-12 was terrible for the stratospheric ozone layer, and I believe information technology is unavailable legally. In 2007 when I gave abroad my 1991 Dodge to someone who needed 'value' transportation, the a/c was notwithstanding common cold and it had never been serviced except for a adding a little R-12 every 3 or 4 years. In that location was a mixed hydrocarbon (no upshot on stratospheric ozone) refrigerant which would piece of work in the old R12systems, merely was unapproved considering information technology was flammable or even explosive. The only real danger I can think of would have been if there would be a total dump into the passenger compartment and it ignited before the windows could be opened.
I have a set of pressure gauges calibrated in psi and in temperatures for R-12 and R-22 and then I could charge my autos with R-12 and my home a/c with R-22.
R-22 was much meliorate for the ozone layer than R-12, but could not be used in motorcar a/c units because it destroyed safety hoses. Safe hoses were necessary to allow relative motion between the compressor on the engine and the condenser and evaporator on the body. R-22 could have been used in autos if they went to an electrically powered compressor mounted on the torso, simply this would have required a very high output alternator and this arrangement was not adopted (except maybe in some hybrids)
I believe R-22 is no longer manufactured in the western countries, but there are ample stores of R-22 to service older home units. My current domicile a/c is over 20 years old, but doesn't leak. I have a 30 lb canteen of R-22 in my garage which I volition manus over for recycling when my abode unit gives up.
