EV Aircon by: Ian
As one who is trying to get everything together for a self build EV I researched a aircon unit for my future car by trying one out in my existing ICE car.I went to a local aircon repair shop and they took a room aircon unit apart and replaced the compressor with a Swedish 12V unit and fitted the compressor and condensor coil in the boot and the evaporator on the back seat and used a reverse cycle setup to provide heating and everything has been working well for the last 3 months. When I get building I am going to install the unit as normally fitted to a car and use the battery heat as the primary heat source and jut dump the heat for summer Great Site

Stuart Brisbane Australia - gets warm there does it? BTW Lynne on submarine we chilled Cokes in the airconditioning duct.
Anyway you can have air conditioning.
Cheapest Salvage old compressor. Keep the electric clutch. Remount so it can drive off the drive motor. You will need some way to turn on the clutch and compressor (existing HVAC control) AND you will need a way to sense motor current and to turn off compressor to prevent motor overload. Easiest is to watch amps and turn off w manual switch.
REGEN you can use the compressor for regen braking probably the easiest is to have a manual switch to engage clutch.
Next cheapest get a "small" DC motor and drive compressor off that.

Awesome!! The information provided by you is very good. It is very useful and helpful. I am really thankful for that. I came across one site which consists of more and more information about Air Conditioning. You can get some other information from that site.
