Fellas,
For quite a while now I've been interested in the potential to change my AC compressor from the belt driven type to one of the brushless DC electric compressors. I could imagine this may add a bit of efficiency, and also allow the use of AC without the engine running for short periods of time(watching battery charge of course). I see that some electric vehicles are using them now and wonder about the potential for a swap. Things that I can think of that may be sticky points:
1) Ensuring cooling capacity is comparable(may require two E compressors to do this)
2) Would need to make an AC delete bracket with idler pulley
3) Would need to come up with a solution to hook two compressors in parallel together and then to the stock lines.
4) Would need to figure out the control scheme of the brushless compressors so the system would adjust refridgerant flow(by changing the brushless motor speed) according to cooling demand.
5) Would need to be mindful of the space that two electric compressors might take
I know this is really far fetched, but Im now at the point that I must do something(at least before summer time) whether go stock or go for an upgraded system. I'm looking for some technical guidance on what cooling capacity I would want to shoot for, and whether or not the stock expansion valve would play nicely with the electric compressors among other things. Thanks!
