Re: [Syncro_T3_Australia] Re: Original circa 1990 aftermarket air conditioning system ... upgradeable?

As with just about everything else, design and functionality improvements are to be found in many automotive components, and this includes air conditioning compressors.  A good example is the Engel refrigerators.  I have one dating back about 20 years and it is extremely powerful in terms of cabinet performance.  It will freeze the contents rock solid in 45 degree temperatures.  I know because I did it accidentally one summer!  It pulls around 5 amps, which is acceptable for such good performance.
The new Engel compressor for the same size cabinet and performance pulls 2.5 amps.  I understand that the improvements are in the drive motor and the design of the compressor.  Yurik's finding appears consistent with improvements in compressor design.

> I'm unclear why it is you keep banging on about ducting.

That is the problem with the Australian a/c systems. The German ducted style works fantastic. I was at the VW Nationals when they were driving people around a test track all day and even though the outside temperature was in the high 20s, it remained cool in the Caravelle.

I know of people that modified the ducts/vents on their Aussie system which improved it. I do not think that a/c technology has really changed much in the last 20 years, so unless you compressor is knackered you will not get much of an improvement.

What is actually wrong with your a/c at the moment Ken?
