Thread: Travel trailer rooftop A/C Unit
06-05-2004, 02:12 AM #1
Had my first experience today with a Coleman (travel trailer) rooftop A/C unit and it left me totally dumbfounded!
Repaired several leaks, evacuated, recharged etc., when checking system pressures....was flaburgasted! Ambient was mild, virtually no load on evaporator, however, I have never seen an R-22 A/C system operate at 30 degree evap with 90 degree condensing!
Anyone available to shed light on this matter. Would be greatly appreciated!
Ah!, and it does have a thermistor embeded in the evaportor, reckon it might protect the compressor from liquid slugging or such because the evap operates so cold!?
