Still it doesn't match a window A/C unit that dumps the condensor's

I didn't say it did. It *will* allow the user to save some amount

energy going to the window A/C unit because the dryer air will be
perceived as cooler to the user. On milder days, some users would
not even feel the need to turn on their A/C.

Air conditioners remove humidity very well too, that's the condensate
that drips from the outside (if they tilt that way). Their plumbing is
sized to keep the evaporator (cooling coils) above freezing which
greatly improves efficiency; freezing water takes a LOT of energy that
you don't get back if the defrost heater melts the ice. Refrigerators
have to give up some efficiency to keep the freezer compartment
frozen.

Yes, a spare refrigerator will dehumidify, but it also heats the
indoor air, so you don't gain much comfort. Better than nothing,
maybe.

I've fixed a few old apartment fridges that had door gasket leaks that
let in more humid air that the evaporator design could tolerate, and
ice built up until it jammed, stalled and burned out the fan.
