Well... I goofed. I posted about my new in-line fan in my dehumidifier thread. I'm sure it didn't have anything to do with my lady's latest blend.
Anyway, to get back to the dehumidifier for a moment... So far, it's working very well. Being able to control it from anywhere via its WiFi is very useful. It can bring down the RH quickly, too. Especially nice is the settable tank level alert.
However, it may be possible (if not today, someday). Here's how:
What would be required is an energy removal mechanism that doesn't require an exhaust port. So, if excess heat could be converted to electricity and that electricity could be returned to the grid, then there you have it. It wouldn't surprise me if the bi-directional charging technologies being developed for electric vehicles were eventually adapted to other applications. All we would need, then, is a way to convert heat energy to electrical energy. That would solve the problem of removing heat energy from the room.

It seems it would be impossible. That's because the room is a closed system, and, barring any leakage, the heat inside wouldn't change. (There is leakage, of course, but let's pretend for the sake of this thought experiment that the room is like the inside of a thermos bottle.) Essentially, no heat is added or lost. It ceases to be a closed system when energy is added to run this environmental-control machine. That additional energy could only increase the heat energy in the room. It could not decrease it.Somebody should make an all in one dehumidifier and a/c that just sits in the room and does it's job without a window port.
