Re: After market aircon
Hi Daan My 302 im building for the F100 is getting a modern BMW compressor, too be honest its not the smallest unit around but is alot lighter than the older type of units. I polished the aluminium and it does not look too out of place on the motor. I plan on removing the heater core, installing an evaporator in its place and using the existing blower motor. It will be crude but I am sure the BMW compressor will make the small bakkie cab extra cold.72XYGT wrote:Wonder if i should'nt go for something modern and compact. What do you guys think?

R12 refrigerant was used until 1992 and used a mineral oil as lubricant.72XYGT wrote:With the new type of gas can the old aircon units still work.

R134 has been in use since 1992 and uses a polyalkaline-glycol oil as lubricant.
These two oils are not compatible.
To convert R12 to R134: replace the compressor with a R132 compressor, replace the receiver dryer, block valve and all the rubber hoses and seals with R134 compatible equipment. Flush the condenser and evaporator with benzine.
Once properly flushed, the system can be assembled and, following the correct procedures, charged with R134.
In a converted system, we have found that the system pressures run about 5Bar higher than with R12 and the efficiency, (cooling output) in some cases are not as good as it was with the R12.

No, but R26 will do nicely.72XYGT wrote:With the new type of gas can the old aircon units still work.

Better make sure your system has no leaks though because R26 is LPG!
Other than the small flambility risks R26 is a great refrigirant. It is used quite a bit in Oz, and one of the Oz standards agencies tried to deliberately set a car AC charged with R26 on fire but no dramas.
It is also used a lot in housing split units in OZ and is starting to be used for splits here in the UK. Also used in ground source heat pump systems because of efficiency gains over R134.
Benefits:
* Works in unmodified old R12 systems
* Is happy with mineral oil
* Cheap
* Easily available
* Doesn't stuff up the environment if it leaks
* Similar efficiency.

Re: After market aircon
hey guys,LPG!i wouldnt go that way,flamable gas in your engine bay....just not sounding right!i would do the 134a conversion or if u have no aircon parts to start with u get some nice looking universal kits!other good thing it consist of al new parts so there is no start up surprises!i also think at the end its also cheaper than sourcing lose parts!i have installed a few of these and i find it to be good value for money

Go do the research. The Australians have tried and tried to make it go bang without any ill effects.
When you install aircon the first thing you do after it is all bolted up is pull a big vacuum. If you have leaks you won't pull the vacuum. If you fill up a leaky system with anything you are wasting your time.
If you do get a leak the gas dissipates quickly.
There is very little gas in a system, several hundred grams only - we are far away from carvan size 15Kg bottles.
You are not scared of the flamable gas generator (carburettor) already in your engine bay, even though it is not sealed and vents to the air, and it is connected to a pump that can deliver a lot of fuel in little time. Those connections have a lot less integrity than aircon systems. Just to help things along an even bigger air pump (the pistons) all the better to make flamable vapour. Geez it even has a ready made ignition source to light it.
But you worry about a little bit of LPG in a extremely well sealed system......
