In a couple of forums where we are working on kit cars with VW air cooled engines and therefore little room for conventional air con compressors etc we are looking at electronic means of getting cooled air into the interior and peltier devices have been mentioned. There is the advantage that we have small two seat cabins, about 2,5 cubic meters so not a lot needed but with ambient external summer temperatures of 30c to 42C and a large, almost horizontal windscreen, internal temps can get as high as 60c+.
I have looked at a few kits and assemblies and I can see where we could use and even utilize these but how COLD if one could expect from say a 6.5A to 10A unit using something like a CPU cooler heat sink and fan.
Alternative idea is to cool the fluid with Peltier devices in an insulated container (like a cool box) and then use that to construct a pumped cooled fluid system passing the pipes through the cooled fluid and a matrix in the car with a fan as normal and again use the heated side when needed for warming the car, when not needed the heat would be vented away or the whole thing just switched off. A/C using peltier devices, is it feasible'
Any brain storming ideas would be very welcome as I can get my head around the engineering side but electronics are limited to 12vDC car systems.
My Mercedes air con delivers as low as 5c at the vents but that is too cold and it is a much larger area.
