To simplify, it is like running your auto dash AC on "recirculate/max" or to "vent air" from the outside. On recirculation it continuously heats or cools the inside air, much like a single hose heat pump/AC. When on the "vent" setting, like a double hose heat pump/AC, it is constantly bringing in fresh exterior air and heating it or cooling it, and is impacted by lower or hotter outside temps.
The single hose unit, like your automobile, depends on air leakage to exchange the stale inside air with fresh outside air.
I am very curious: How much air does yours push out through the vent hose? I know that is rather subjective but I will say that our portable AC pushes ALOT of hot air out.
My vent hose blows out through an adapter on my engine dog house. The air is quite cold and the volume is less than what is being blown inside the coach. This sort of make sense since there is only one three speed blower motor and it is used to push air over the coils and back inside the coach as well as exhausting the stale air outside. I am not sure if the double hose units use two fan motors or just one, like my single hose unit.
