Would it be possible to remove the drive belt from the aircon compressor and fit an electric motor to drive this compressor instead? I'm not aware that the engine speed affects the operation of the compressor so an constant speed motor would probably work.
The electrical supply to the compressor clutch could be the supply to the new motor (possibly through a relay if it wasn't sufficiently rated to take the load of a motor).
I ask as I would like to be able to switch on the aircon remotely and have it running from my second battery without the engine running. I realise I would then need to swap the supply for the internal heater fan controls to run from the second battery aswell or at least bypass the ignition switch.

Does anybody know if this would be possible? Your thoughts and comments would be greatly appreciated!
 
get your calculator out, calculate hp required to drive compressor, mechanical losses in efficiency, electrical losses in efficiency. I 'd suggest that alternator is weak link
why not just rip it all out an fit gen set
 
You would need a bloody big motor and an even bigger battery!

Why not fit a donkey engine in the boot? Run it on gas with a remote control to the starter motor, job done!!

Why??????
 
Why is a very good question! I regularly drive in southern France and it is not uncommon for it to be 50 degrees celsius there. If I leave the car even for 15-20 mins, it is too hot to get back into. It doesn't warrant leaving the engine running all that time (could be an hour on occasions) but it would be beneficial to have the aircon running during that time.
As ridiculous as it sounds, a donkey engine may be the way forward! It could be a single cylinder diesel which would run all day on an eggcup of diesel.
Certainly worth thinking about. I appreciate the loading would be high for an electric motor.

Thanks for the replies!
 
Just chuck a white sheet over the seats, works for me and if you cover the steering wheel as well not only can you sit on the seats you can steer as well, always a bonus !
 
I think this could be the answer... You do have a tow bar dont you ??

Here you go, the answer to your problem, quick easy instillation in the load area of any Range Rover (10 minutes max), just plug n play, instant cool air and the power supply, also allows recharging of flat vehicle battery when RF receiver discharges main vehicle battery.....:D....;)
