David,
When you say the crawl space is "fully damp proofed", do you mean that there is a layer of plastic or rubber membrane under the concrete? Additionally, for fully damp-proofing, I understand it's necessary to vent the area under the plastic seal up a flue to the roof level. This also safely vents any radon gas.
My understanding is that it's good to vent a crawl space, so the air bricks are probably not hurting the humidity levels.
It's possible that the house plants elsewhere in the home are raising the humidity level in your room. Keep in mind that whatever water you put into them will wind up in the home air - it has no place else to go. And humidity seeks its own level. It wants to equalize throughout the home; only a moisture barrier in the walls, ceilings, and floors will prevent it from doing that (think thick plastic sheeting).
One possible way to reduce indoor humidity is to get a dishwasher with condensation drying, like the Bosch/Asko/Miele euro designs. American style models simply vent the bulk of the moisture into the home. The euro designs send most of it down the drain.
The humidity in my home is generally around 60%. It's lower in the winter during dry spells and in the hottest days of summer. I'd like it to be lower but I don't think the dust mites bother me anyway.
Louis,
It's possible that the rate of infiltration of humidity from outside your room is equal to the rate at which the dehumidifier can remove it. But it should still be putting water in the tank no matter what. If it's not producing any water in the tank below a certain humidity level, I also would suspect that it's defective, especially since that model has a history of defects.
