DIY DeHumidifier

[it1sasecret]

alright while thinking about an easy to deal with and cheap dehumidifier for my DIY HUMIDISTAT/THERMOSTAT i decided why not make my own....
heres the components:
2 Baffles

1 fan

1 container

some pipe

basically you put a baffle on each side of the container and fill the container with your favorite water absorbent material, hook the pipe to one and the other side of the pipe to the fan and there you go.

here is my diagram its just the rough sketch i will be building it tomorrow and will take some pictures, let me know if you have any questions

key design feature is the baffles, it keeps the water absorbent material isolated from the air to keep it from lowering the humidity but kick on the fan and the baffles open, the fan sucks the over saturated air through the container over the material and releases the dryer air.
thanks

So the air flowing over the material will have some of the moisture extracted by the condensation of moisture on the material? Fiberglass, fluffed up a bit to provide some friction, might prove useful as the initial material the air comes in contact with something absorbant under that?

Would your concept work by blowing the moist air through the material versus over the material as in your great diagram?

yes it would, i have it set up in this manner because of the fan i will be using, and the ease of opening the container to replace the material. another alteration would be using the carbon scrubber designs already in the diy section but filling them up with the moisture absorbent crystals, the only flaw i see with that is keeping the crystals isolated from the correctly saturated air. thats the beauty of my design the baffles are kept closed when not needed.

good notes though
thanks

You need to look up dessicant pellets! They are used in alot of things to control moisture. When ever you buy electronics, it is the little pacage in the bottom of the box. They are totally reuseable!! Make a filter using them like activated carbon in a carbon filter. Google it!

thats what the system will use, they work on their own but this allows them to be isolated from the air when the rh levels are steady

If you are using the reusable dessicant pellets that are colored blue USE CAUTION. They get that color from being treated with sodium Cobalt which is a heavy metal. Use PPE when handling the product and you will be fine but I just thought you should know. Sorry, I am a Haz/Mat tech so safe today/ home tonight, to roll one. How are you going to control rH. The most common use of that product is in air compressor driers. = 0.0 rH or close depending on current saturation of material. ? looking forward to your review of the final product. Nice work. Its cool to see guys thinking outside the box.
