Combating the Summer Heat

[Jolly Roger bus 223]

For the record, those rooftop A/C units are called "self contained units" (because the evaporator and condenser are in the same box, like a window unit)


Are you going to put a generator on the trailer?


I'm wondering if anyone here has taken the original bus system, combined it all into 1 box using a small gas engine to drive the compressor?

those would be called APU's like on a refrigerated trailer.
auxilliary package units.

Noted, however, refrigeration systems and air conditioning/hvac systems have different requirements.


Still wondering if any one has "recycled", so to speak, their bus air conditioning system ( compressor, condenser, evaporators, fans) into a self contained system with a small engine driving the compressor.



or


has anyone just hooked up the compressor to a small engine and re-routed the refrigerant lines and left the rest of the system intact/inplace?



Either one would allow the use of the a/c regardless of whether the bus engine is running. Probably require a fairly large "small" engine with electric start. cheaper? too much noise? too much space?

Yes. This is possible. Search "pony motor ac", etc
Maybe JoeBlack did this?

Some buses do have two engines.
