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.
