New plan , hacking a portable Ac with reversing valve that should have defrost control via some sensor. that has me thinking to mount the evape and fan unit outside and leave the case with compressor condenser and controls inside.
a Mini split on a short chain , slip the evap and fan unit out the window and let it rip.
I think its outlet fan will be powerful enough I would add a fan to cool the indoor compressor
That's the Mods I think of what else do i need to do with a automatic type unit like this ?
