cadillac - continue ac discussion
so what about thermostat for cabin temperature.... controller for the solenoid? I wonder if there is an off the shelf unit that could control a liquid line valve, and fans. The front vintage air heater/defrost/ac firewall mounted unit is all electric and will be operated by the driver/shotgun. The rear could have some sort of manual controls driver override with an automatic temperature control at the rear. You seem to have more experience with "custom" ac set ups.
I am certain I can do ducting to feed the back side of condensors cool air from under the bus. Have you seen highpressure line with fins? Might as well use some sort of hard line from the front to the rear with cooling fins, it will be a run of 15' or more... wonder what kind of temperature drop I can get... The way I do air flow is yarn testing and watching air flow. or in a tight spot under I can use a camera. i wonder if can suck air from the side, and use that air behind the rear end to smooth trailing side air flow..... I will have do some testing to see what works or what I can make work in terms smoothest air flow. I could do a water manometer and look for high pressure zones to feed the condensor and go from there. Still work to do.
but, this is the kind of stuff i really dig.
