A/C Compressor Replacement!

[senator02103]

My mechanic looked at it today...there is actually a leak in my pipes

Some of thw aftermarket drop in gases work well, better than R12 and R134A BUT they they are flammable!

the hydrocarbon gasses are not too good for your system
yes they get real cold
but the gas in the system serves as a coolant, and the system only gets a 1/3 fill on hydrocarbons..... poor compressors dont stand a chance
also the hydrocarbon blends tend to settle and the components leak out at different rates so pretty soon the blend is out of whack
we were going to go down the hydrocarbon track when this licencing BS started up, but after doing our homework, decided that we'd just stay with R134a
of course i cant wait until CO2 becomes mainstream

[gtrtwinturbo]

though they were phasing out r134a for some new one thats so much better (2% or so) for enviroment???
bout the time that the distrubtion rights for r134a run out????

"allegedly" better flourocarbon blend by Du-pont/Honeywell HFO-1234yf (2,3,3,3-Tetrafluoroprop-1-ene)
but the europeans seem to be heading for CO2
not to say it has its merits but im not sold on it yet
guess time will tell if dupont/honeywell can pull the wool over the greenies eyes

CO2 systems can do both heating and cooling apparently. AND we will finally be allowed to do our own regassing I imagine.

you can heat and cool with any gas, its just a matter of swapping the flow thru the evap and condensor... but its more economical to use some of the waste heat from the engine to heat the cabin
also i wouldnt count on being able to regas yourself, CO2 systems work at much higher pressures and CO2 is regarded as a global warming gas

You breathe out CO2, I highly doubt they will stop you from regassing your own system based on it being a 'global warming gas'.

More likely is the high pressure system required.....

I dont see the issue with degassing a CO2 based system.....I'll just hold my breath for a minute to compensate.

CO2 or R744 runs 7 to 10 times higher pressure, uses a scroll type electric compressor - at least in an implementation by Denso.Can do both heating and cooling in an all electric car.

breathing out CO2 and dumping chemicaly obtained CO2 are two different things the former is part of the carbon cycle and the later loads up the ecosystem

the most effective way to heat a cars interior when there is no engine heat is with an electric heating element
