Does anyone know how one might determine whether a Leaf has the liquid-based heating/cooling circuit I've seen mentioned in a few other posts? I'm curious how closely coupled the two systems are; is the heating liquid what circulates through the cabin heat exchanger, or are there separate exchangers for heating and cooling? How cold can the liquid coolant be chilled?
I ask for a very simple reason: I'm looking to dump up to a few thousand watts of heat through a liquid-liquid or liquid-gas heat-exchanger and need a way to chill the working coolant. You can probably guess what the source of heating is (or will be). Since I'll be linking to the vehicle CAN through one point or another (take a guess why) it would be much simpler (and cheaper, and safer, and lighter...) to tap into the vehicle's HVAC rather than install an entirely separate one elsewhere on the car.
If there are resources or schematics for the HVAC system available, it would be awesome to see!
Additionally, any information on controlling the HVAC through VehicleCAN would be very helpful. Things like registers for setting pump speeds, target temperatures, or for reading temperature sensors...
I hope to share more about this project going forward, and I think it's an idea lots of you will like.
