Correct but why remove moisture from air you're pumping outside? The dehumidifier by itself will certainly lower humidity in the room but if you're taking all the air that it is exhausting out of it and sending it outside the dehumidifier is not doing anything more for you than a regular fan would. Yes you're condensing water but unless your goal is to make water you're not gaining anything from using the dehumidifier.

Is this clear? I'm not sure if I'm explaining this well, maybe others can help.
