Air dehumidifier

The air dehumidifier is now popular along with the humidifier. Strange as it may sound, but both instruments of diverse action allow creating a comfortable microclimate not only in different houses and apartments, but also in one housing. The choice of a suitable fixture depends on the quality of the building materials used in the building, the chosen finishes and the peculiarities of the life of a particular family. What is needed for the dehumidifier, the principles of its operation, and also how to make the dehumidifier with your own hands, you can find out here.

What is the purpose of using an air dehumidifier in an apartment?

The most undesirable and unexpected guests in our homes are fungus and mold. Their disputes regularly hang 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! Sufficient temperature of 20 degrees and above with a relative humidity of 80%, so that you can see with an unaided eye the growth of colonies of fungi and mold on the walls of the room.

And why, for example, does a neighbor have such undesirable troubles? The answer is quite simple: the air temperature throughout the house is often the same, but the humidity can vary greatly.

Dehumidifier

In the fight against the effects of dampness, you can, of course, significantly reduce the temperature in the apartment. Yes, that's just who wants to live in a constant cold? That is why the best way out of this situation is to install a dehumidifier. With your hands you will make it or buy a ready-made device - here you have to choose personally for you.

Important! Among other things, he becomes the guardian of the health of the inhabitants of the apartment. The immunity of the human body is in direct proportion to the humidity of the air that is around it. Than it will be drier, the more difficult it will be for harmful bacteria and harmful microorganisms to multiply.

Algorithm for creating a dehumidifier with your own hands

Dehumidification is carried out by three simple principles:

• heating;
• adsorption;
• condensation.

It would seem, with the help of heating, it is easiest to dry the air in a room. But the reality is that nobody will like it a day or so to be in an excessively hot apartment. That is why we consider the following two options: condensation and adsorption of moisture. To make dehumidifiers based on these principles, you can without help.

Adsorption dehydrator

This is probably the simplest option, which does not require much time and money:

1. Take 2 plastic bottles. Each volume is not less than 2 liters.
2. The bottom of one of the bottles is perforated with a hot nail or knitting needle. Divide the tank into two equal halves.
3. In the lower, already perforated, part of the bottle, insert the second half so that it is pointed with the neck pointing down.
4. On the neck, be sure to tighten the stopper, having made a large number of holes in it with a hot nail or an awl.
5. Pour any absorbent into the top of your design.

Important! Optimum option - silica gel, which has powerful absorbent options. They are easily restored after drying of the used substance. For one dehumidifier, you will need approximately 250 grams of silica gel.

1. Cut the bottom of the second bottle, fix the fan inside the tank, which is needed in order to blow towards the already cut bottom. The pressure unit of the device is located 7-10 cm from the cut off bottom.

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

1. Place the bottled bottle on a container that contains the adsorbent.
2. Place the joint thoroughly with tape for better sealing.
3. Unscrew the lid from the second bottle in order to ensure airflow.

Important! Having done all these small manipulations, you got a low-noise, but quite effective device that is powered by a USB connector or charging for a mobile phone. The fan generates an inflow force, thereby blowing air through the silica gel, and already drained flow exits through the perforations at the bottom of the structure.

Condensing drier

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 proceed:

1. Remove the door from the refrigerator and freezer compartments by disassembling the hinges. To do this is very simple, because most models are equipped with removable doors.
2. For the size of the removed doors, measure 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 the hole into which the fan will be mounted later.

Important! The dimensions of the hole must match the protective grille of the fan that you found.

1. Mount the fan in the plate, fasten the grill with the screws.

Important! The device should work as a supply air unit, that is, blow out the flow of moist air into the refrigerator.

1. 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 hole for the fan.
2. Establish a system of removing excess condensate from the body, put in order or modify it. To do this, connect the outer pipe, which is above the compressor with a storage tank, a polymer hose.
3. Secure the plexiglass with self-tapping screws at the place where the refrigerator door should be.

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

What is a typical air dehumidifier?

Anyone who knows how the refrigerator works, the principle of the dehumidifier does not seem very confusing.

Principle of operation

Inside also Freon circulates, and there are four phase states that allow you to cool the air entering the room first, thereby taking all the moisture out of it, and then re-heating and releasing it into the room.

Here are the components on which the basics of the operation of air dehumidifiers are kept:

• evaporation;
• compression;
• condensation.

Device

In order to provide status data, there are four components. The structure of the air dryer device is set:

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

Important! The output stream is heated by means of a condenser, where Freon is reincarnated into a liquid, giving up previously collected heat.

Functionality of

It remains to add that in the factory air dehumidifiers you can adjust 2 indoor climate parameters:

• temperature;
• humidity.

In addition, it is possible to adjust the fan speed, thus affecting the performance. The humidity of the room is higher, the speed should be greater. So, the dehumidifier in the bathroom should work much faster.

Important! Individual models are equipped with an ultraviolet disinfectant.

Important nuance of choice

The parameters of the purchased device exceed the parameters of the vacuum cleaner by 2 times. This is a fairly large-scale device, which, to all other things, can be relatively noisy.

Important! If you buy an air dehumidifier, then the acoustic level should be about 46 dB.For greater understanding, most refrigerators operate in the range of 42 to 52 dB.

Now you know everything about how a household air dryer works, what it can do, how convenient it is. And for comparison - you can first make a more budget version of the device. For this, you have 2 step-by-step instructions for assembling the dehumidifier yourself with hand tools. Perhaps, you will get such an interesting and effective device that you hardly want to spend an impressive amount on modern home appliances from industrial manufacturers.
