Air dryer

Often, when shopping in consumer electronics stores, I noticed such a device as a humidifier and had never seen a dehumidifier. Someone will now say - so in almost any air conditioner there is such a function as an air dryer. In each, but not in everyone. But still not always everyone can afford air conditioning. Moreover, the air dryer, which I will tell you today, has several advantages, one of which is noiselessness. I needed a dehumidifier for my apartment on the first floor. There is such humidity at home that even a mold fungus on the walls comes through. So, the air dryer that I built consists of almost three parts: two radiators and a Peltier element. I think most avid gamers who like to pump their computers to madness know him. If in a nutshell - this device, when a current is applied to it, begins to emit cold on one side and heat on the other. On the one hand, we will fight against heat by blowing the radiator out of the cooler.And on the other hand there will be a cold - it's what we need.  Air Dryer
Let's get started. Prepare the following: a radiator with a cooler, a second radiator is smaller, a Peltier element (if you are interested in taking it), a thermally conductive paste (you can buy it in any computer room) and a pair of screws for the structure tie. First and foremost I drill holes in the radiators - in the second radiator holes a little more. Then I take the Peltier element and smear its side with thermal paste on both sides. Smear a thin layer, otherwise the paste will squeeze out strongly. I put the plastered element between the radiators and twist the screws. If you repeat the construction, twist it carefully, without fanaticism, otherwise the element will crack.

That's it! Now fastensomewhere our dehumidifier and put the bottom of the vessel to collect the liquid. The principle of the device is very simple - the side is cooled and the moisture in the air condenses on it. I hope you are not a boy of five years old and you did this at school). We connect the cooler in parallel with the element and supply 12-15 volts. If a small radiator has started to warm up, we change the polarity of the element.

For clarity, I connected a thermometer and it can be seen that the temperature very quickly dropped to 6 degrees. After some time, the radiator began to fog up and began to drip condensate. After 15-20 minutes of work, the temperature dropped to 4 degrees Celsius.

I want to note that the size of a large radiator should be chosen from the formula: what more is better. But a small radiator needs to be taken not very large, otherwise the temperature on it will be below zero and all the moisture on it will turn into ice and freeze,but this is not good.
