Not in this case. According to the manual
, this particular unit is a single-hose design, and that hose can be the cool air output (sitting outside and duct cooled air into the trailer as Cricket proposed), or the hot air exhaust (sitting inside and duct hot exhaust outside, as Bob assumes).
Any single-hose unit has a problem:
- in the cool-air-output mode, it has to cool hot outside air all the way down to the desired output temperature
- in the hot-air-exhaust mode, it sucks hot outside air into the trailer to make up for what it exhausts
Didn't we very recently go through this topic?
