Cabin Dehumidifier.

[sailful]

Has anyone built a dehumidifier based on the newer 12 volt compressors? Even if you could only use it when on shore power or when the engine is running it should make a huge difference.
Thanks for your feedback.

unless they have changed a dehumidifier is an airconditioner. the only difference is both the evaporator and condenser have the cabin air blown over both, so no cooling, actually a little heat is added.
A small AC unit will dehumidify and cool

In the fall and winter I am not looking for cooling at all. At that time of the year I am looking for heat and dehumidification.

They pull a lot of power! So unless you have a large battery bank and a means of charging it you're

But, if you want to go through all the trouble I'm sure one could be made from a frig. Compressor and a plastic box. Basically, they are an air con which cycles on and off. When its in the freeze mode the coils collect the moisture in the room. Then it shuts down with a slow fan on the coils, in which the ice melts and drips in a pan. Then it starts up again.

But if your on shore power or 3000 watt inverter, just buy a 115V unite.

BTW this is what a lot of RVers use..... Amazon.com: Dry-Packs 750 Gram Silica Gel Canister Dehumidifier - Moisture Indicating: Home & Kitchen

Evadry 2200 with 12v cord. But what's so wrong with using 110v?

The Eva-Dry 2200 looks like it would do the job. Never heard of it before. Thanks for the info "thinwater". Any of the regular 120 volt units that I have seen are too big for my application.

Thanks

In a small cabin, like mine, the Peltier Effect dehumidifiers like the Eva Dry work very well. I drilled a hole in the tank of mine, stuck some aquarium air hose in it, and led the hose to the sink drain. If I didn't do that I'd have to empty the tank almost every day.
