How to choose an air dehumidifier. Recommended models

Excess humidity in the room can cause mold and other microorganisms. Don't know how to choose a good air dehumidifier and solve this problem? We will tell you.

Choose an air dehumidifier: The best models 2020 year

Most often, there is too much moisture in the air in the private sector or in coastal cities. Breathing is uncomfortable, fungus appears on the walls, wooden furniture swells – pleasant enough. In this case, you need to pay attention to such a device as a dehumidifier. What are they, and which model should be paid to, We'll tell you in this post.

The principle of operation of the dehumidifier

The air dryer works like a regular air conditioner. The device has two heat exchangers, filled with refrigerant. Getting into the first, the air cools and gives off moisture, which turns into condensate. Then the air is heated again in the second heat exchanger, and comes out of the device already dried.

How to choose air dehumidifier as intended?

There are several types of dehumidifiers, each of which is designed for specific tasks:

• Household. This is an ordinary home dehumidifier, which is convenient to use for small rooms. The vast majority of devices of this type have low performance, which makes them compact and light. They are also practically silent, so they can work even at night.
  Household dehumidifiers also cope well with the humidity of garages and offices. They are easy to move from room to room: weigh very little. A good dehumidifier for rooms up to 20 m2 – MYCOND Roomer 12, is worth 5-6 thousand. UAH.
• For pools. These devices are designed to drain air in rooms with a covered pool. Their main advantage – Possibility of continuous work. That is,, during the whole day, the unit can supply air of optimal temperature and humidity to the room. In a day, such devices are capable of drying up to 70 – 80 l of water. Pool devices no point to buy in the house, And they cost a lot of money. However, If you have a private bath or sauna in your house (not in a separate room), then you should buy such a device. Recommended Model – MyCond MBA 07 G, price in the ventbazar.ua store from 70 000 UAH.
• Channels. Continuous dehumidifiers for round-the-clock use. They are not installed indoors with a pool, And outside. Their main advantage is the large airflow, Created by a fan. Some devices are able to drive away to 1500 m 3 / year. Drawback – The high cost of such devices. Recommended Model – Dantherm CDP 125, this Buy air dehumidifier You can approximately 300 000 UAH.
• Adsorption. It's quite unusual dehumidifiers, who work on a completely different principle. Unlike all the above types, here moisture absorption is carried out by a special substance. This technology makes it possible to drain the room even at negative temperatures. Basically adsorption dehumidifiers buy for large freezers and for grocery warehouses. Inexpensive efficient mobile model – Trotec TTK 200 Cope with the drainage 500 square meters. The price is approximately 65 000 UAH.

Which air dehumidifier is better to buy from the above? If you need a device for an apartment or house, quite domestic. You should pay attention to other types only then, if there is an extreme technological necessity.

We choose the performance of the dehumidifier correct

For dehumidifiers, performance is measured in the amount of moisture removed from the air. Such devices usually have performance from 10 – 50 l per day. The more productivity – the more and the size of the device.

Which model is needed in your case? For a normal well -being is necessary, to keep the room in the room near 30 – 45% – not taller. In accordance, At elevated level it must be removed. Here is how the percentage of humidity and the required device performance:

• 50 – 60% – 10 – 15 l per day.
• 70 – 80% – 15 – 20 l per day.
• Over 90% – 30 – 50 l per day.

pay attention! For, To find out the level of humidity, It is necessary to use a hygrometer. In most cases, a performance with a performance up to 20 l per day. Can be taken, example, inexpensive Ballu BDH-20l , able to serve before 24 m2 of area.

What should the air exchange be?

The intensity of air exchange depends on the productivity of the fan. The larger the room, the greater the air exchange rate is required, to make the air always fresh. pay attention, that the size of the room, that is serviced and air exchange may vary in different models. Example, In one model when servicing 24 m2 area of ​​air exchange can be 30 m 3/year, Whereas the second with the same service area 50 – 70 m 3/year.

Choosing a fan productivity, should rely on the height of the ceilings (With the same area of ​​volume may be different) and the length of the diagonals. In the farthest corners can accumulate moisture, through which mold and fungus will develop. So that this does not happen, need to take a device with sufficient air exchange. Mitsubishi Electric Smart Home MJ-E20BG-R1 with air exchange 210 m3 / year.

Additional dehumidifiers

The following additional features can be key when choosing the right model:

• Hygrostat. Built -in sensor, which determines the humidity throughout the device. It determines the moisture content in the air and includes the device, If the humidity level increases. So, You don't have to run a dehumidifier manually – he will work automatically.
• Air flow rate. This feature allows you to adjust the speed of the fan and, in accordance, the force of air flow. It is very convenient, If the device has some power supply. A strong air flow is not always needed, And by lowering the speed of the fan rotation, can save electricity and reduce the volume of work
• Authorisma. Function prevents excessive cooling of parts. During drainage by means of a refrigeration system, extra heat is discharged. However, the same process affects the conversion of drops into frost, that is undesirable for a dehumidifier. Ago, launching this mode, can avoid unnecessary cooling of the system and, As a result, Continue the life of the device.
