Custom AC and Electric AC Compressors

[Warren99]

I engine swapped my MJ and theres no room for a belt driven ac compressor so I'm gonna try out one of those electric ones I've seen. Should be able to just upgrade my alternator, and then make custom lines/hoses to the stock jeep A/C components.

I was curious if anyone had any advice like would longer A/C lines affect the effectiveness much? Because I relocated my battery to under my bed and theres not much room in the engine bay so ideally I'd like to mount the electric compressor somewhere under the bed as well. 

Also wondering if anyone has any advice for making the system more efficient, like instead of just using new components for a renix era A/C system, maybe I would be better off using components from a high output system, or an entirely different car altogether. I guess I mean like could I make it better by using a "better" receiver/drier or expansion valve, or maybe none of that really matters and it mostly boils down to the compressor, amount of freon, length of hoses, amount of air moving over condenser, etc. I don't really know much about A/C systems. But I should be able to just mix n match whatever with an electric compressor and the jeep evap core since I figured I can just get one of those hose crimping kits and make my own lines.

 

here's an example of the type of compressor I mean

Swapping in the later model “plate and fin” evaporator and condenser is a good start. Takes some fitting work but is a much more efficient design than the old tube and fine designs. The compressor volume to evaporator size ratio is key for making a good AC system. What engine are you running? I’d try to keep the compressor under the hood if possible as the power draw for an electric compressor will be substantial. Custom hoses/lines is the easier part.

OM606, 3.0 Mercedes turbo diesel. My battery is under my bed on the side of the frame rail now, so mounting the compressor back there would be better for the power draw. I'm wondering how much better the plate and fin design would help, I put a brand new evap core in like 2,000 miles ago before I pulled the 4.0 out and I'm really not feeling like pulling the dash and hvac box out again.
