DIY air dryer

A dehumidifier is popular today along with a humidifier. No matter how strange it may sound, but both devices of diverse action allow you to create a comfortable microclimate not only in different houses and apartments, but also in the same housing. The choice of a suitable fixture depends on the quality of the building materials used at the base of the building, the chosen finish and the household features of a particular family. For what a desiccant is needed, the principles of its action, as well as how to make a dehumidifier with your own hands, you can find out here.

For what purposes is an air dryer used in an apartment?

The most unwanted and unexpected guests in our homes are fungus and mold. Their debate regularly hovers around. But in most cases they are at rest, because in order for them to act, they need certain conditions, namely:

• high temperature in the room;
• humidity.

Important! A temperature of 20 degrees and above with a relative humidity of 80% is enough for you to see with the naked eye the growth of colonies of fungi and mold on the walls of the room. If you already have this situation, follow the link to another article and read about mold killing.

And why then, for example, the neighbor does not have such undesirable troubles? The answer is quite simple: the air temperature in the whole house is most often the same, but humidity can seriously vary.

Air Dryer

In the fight against the effects of dampness, you can, of course, significantly reduce the temperature in the apartment. But who wants to live in constant cold? That is why the best way out of this situation is to install an air dryer. With your own hands you will make it or buy a ready-made device - here you already have to choose personally.

Important! Among other things, he becomes the guardian of the health of the inhabitants of the apartment. The immunity of the human body is directly dependent on the humidity of the air that is around it. The drier it is, the harder it will be for harmful bacteria and harmful microorganisms to multiply.

Do-it-yourself algorithm for creating a dehumidifier

Air drying is carried out by three simple principles:

• heat;
• adsorption;
• condensation.

It would seem that with the help of heating it is easiest to dry the air in the room. But the reality is that no one will like to spend days in an excessively hot apartment. That is why we will consider the following 2 options: condensation and adsorption of moisture. You can make dehumidifiers based on these principles without outside help.

Adsorption Dryer

This is probably the easiest option that does not require large time and financial costs:

1. Take 2 plastic bottles. Each volume is not less than 2 liters.
2. Perforate the bottom of one of the bottles with a hot nail or knitting needle. Divide the container into two equal halves.
3. Insert the second half into the bottom, already perforated, part of the bottle so that it faces down with its neck.
4. Be sure to tighten the stopper by making a large number of holes in it with a hot nail or awl.
5. Pour any absorbent into the top of your structure.

Important! The best option is silica gel, which has powerful absorbent options. They are quite easily restored after drying the used substance. For one desiccant you will need approximately 250 grams of silica gel.

6. Cut the bottom of the second bottle, inside the container, fix the fan, which is needed in order to blow towards the already cut bottom. Position the pressure unit of the device 7–10 cm from the cut bottom.

Important! To do this, you can use a USB fan or a cooler that is designed to cool computer processors.

7. Put the bottle with the cut bottom on the container that contains the adsorbent.
8. Thoroughly wrap the joint at the joint for better sealing.
9. Unscrew the cap from the second bottle in order to ensure air flow.

Important! After doing all these small manipulations, you get a low-noise, but quite effective device that is powered by a USB-connector or charging for a mobile phone. The fan creates an inflow force, thereby driving air through the silica gel, and the already dried stream flows through the perforations from the bottom of the structure.

In addition to dehumidifiers, there are many more effective ways to solve the problem that we have collected for you separately in a post "How to get rid of humidity in the apartment?".

Condensation Dryer

This unit is somewhat more complicated than the previous one, but here the basis of its design can be found in every house. Roughly speaking, this dehumidifier can be made with your own hands, for example, from a forgotten refrigerator.

How to act:

1. Remove the door from the refrigerator and freezer compartments by dismantling the hinges. This is very simple, because most models are equipped with removable doors.
2. According to the size of the removed doors, measure the plexiglass plates, the thickness of which will be at least 3 mm.
3. At a distance of approximately 35 cm from the edge of the plate, mark and cut a hole into which a fan will subsequently be mounted.

Important! The dimensions of the holes should match the fan guard you found.

4. Mount the fan in the plate, fix its grill using self-tapping screws.

Important! The device should work as a forced-air pressure unit, that is, blow out a stream of moist air inside the refrigerator.

5. At the top of the plexiglass plate, make a series of holes with a drill. Their total area should coincide with the area of ​​the fan hole.
6. Put the regular system for removing excess condensate from the body in order or modify it. To do this, connect the outer pipe, which is located above the compressor with the storage tank, with a polymer hose.
7. Fix plexiglass with self-tapping screws in the place where the refrigerator door should be.

Important! In order to achieve greater sealing at the joints and insulate them, use a self-adhesive tape or silicone.

What is a typical dehumidifier?

Anyone who knows how a refrigerator works, the principle of operation of an air dryer will not seem very confusing.

Principle of operation

Freon also circulates inside, and there are four phase states that allow you to first cool the air entering the room, thereby taking all the moisture from it, and then reheating it and letting it out into the room.

Important! Most often, problems with humidity levels occur when the ventilation system is not working properly. Check it at least in the most elementary ways - by bringing a lit match or by attaching a sheet of paper, and then we will show you how to solve the problem, establish a microclimate in the house andwhere to go if ventilation does not work.

Here are the components on which the foundations of the action of air dehumidifiers are held:

• evaporation;
• compression;
• condensation.

Device

In order to provide these conditions, there are four design elements. The composition of the device dehumidifier set:

• capillary tube;
• compressor;
• condenser;
• evaporator.

Important! The output stream is heated using a condenser, where Freon transforms into a liquid, giving off the previously collected heat.

Functionality

It remains to add that in the factory air dehumidifiers, 2 parameters of the indoor microclimate can be adjusted:

• temperature
• humidity.

In addition, it is possible to control the fan speed, thereby affecting performance. The higher the humidity in the room, the higher the speed. So, the dehumidifier in the bathroom should work much faster.

Important! Some models are equipped with an ultraviolet disinfectant.

An important nuance of choice

In terms of its parameters, the purchased appliance exceeds the parameters of a vacuum cleaner by 2 times. This is a fairly large-scale device, which, among other things, can be relatively noisy.

Important! If you buy an air dryer, then the acoustic level should be about 46 dB. For a better understanding, most refrigerators range from 42 to 52 dB.

Now you know everything about how a household dehumidifier works, what it can do, how convenient it is. And for comparison - you can first make a more budget version of the device. To do this, you have 2 step-by-step instructions for assembling a dehumidifier with your own hands from improvised means. Perhaps you will get such an interesting and effective device that you are unlikely to want to spend an impressive amount on modern home appliances from industrial manufacturers.
