RE: Prostar ac

[Lonestar10]

I would think if you wanted an old style setup with better reliability.

you could probably use the same compressor/condensor/evaps all that stuff but a few custom hoses/lines. granted at the cost a rawze arduino might be cheaper.

but as far as i can think of.

some custom wiring/relays

Put AC system on a toggle switch
On custom lines from/to compressor maybe 2 High pressure cutout switches 1 switch around 300ish PSI turns on fan. 2nd switch 350-400PSI shuts off AC compressor.

A LP Cutout under 10-15lbs cuts out compressor.
and possibly some way to cycle compressor if evap gets to cold. how idk not that inclined into electrical.
then all the custom wiring to get everything to work correctly. this is probably the simplest way to have a mechanical setup.

or

find and some how mount a compressor with a pressure relief system that puts high pressure back to the suction of the pump i believe APADs or whatever had this type of compressor

1 HP switch to turn on the fan
1 LP switch to cycle compressor

i could be talking out my ass but as far as mechanical thats a way in my mind to get one to work if you body controller drives you to drinking.
