Windiness as a life rate

Ventilation settings. The main characteristics of models, manufacturers, prices. Recommendations for choosing and installing.

It is unlikely that opponents of the statement are that clean fresh air is good, pleasant, useful, and dusty and ridden, harmful, without. No wonder Humanity has long been chanting "drinking" sea breeze or a "crystal" atmosphere of mountain peaks. Involation, suffocating Smyrad Megapolis associated with the horrors of the civilization stood in a dead end.

A grill with small cells makes Fisher-Price fans blades inaccessible to children. According to the approval of specialists engaged in the installation of ventilation equipment, most often normal air circulation in the house is violated by the fault of the tenants themselves. For example, plastic windows-glass windows are very popular today, it is practically sealed by an apartment. As a result, natural ventilation is simply impossible. This must take into account anyone who plans to purchase the windows of this type. Increased attention requires the shaft of general ventilation at home. Sometimes, in violation of all sanitary standards, they are subjected to refitting or even tightly cleaned. In this case, the problems with the receipt of fresh air may occur not only in the apartment of the intruder, but also at his neighbors.

However, communal ventilation systems in typical apartment buildings, unfortunately, are far from perfect. This is especially noticeable in old buildings, where the air duct is lined with brick. Easily accumulating dust leads to a narrowing of the air canal and, accordingly, falling its bandwidth. Vitoga We have a poorly ventilated, raw, disappeared kitchen dwelling, and anyone else can no longer be a comfort or a real cozy.

Duracraft. Silent motor, light, air construction - what else is it necessary for normal operation? If natural ventilation of the room is impossible or insufficient, it is replaced or complemented by the forced-different kind of ventilating installations.

By design, fans are divided into axial and centrifugal (radial). Including more often can be encountered with axial-table, outdoor or ceiling "turntables". Centrifugal fans are characterized by the ability to create a strong air pressure. Used mainly in cases where you need to quickly "blow" large spaces.

In terms of purpose, the supply, exhaust and mixing ventilation units differ. The main task of stretching is removed from the closed room odors and accumulated harmful substances. The supply unit provides free air intake. The mysterious fans include the simplest desktop models (familiar to us as an indispensable attribute of the head of the era of developed socialism). They are intended solely to overclock the air around the room and its more efficient mixing.

If you need to install a fan in the bathroom or shower, it is vital to take care of electrical safety. First, when buying, be sure to specify whether this model can be used in the water-saturated medium. Secondly, in "wet" premises a fan must be beyond the reach of man.

Thirdly, we advise you to choose the so-called low-voltage (12-24V) models. The degree of electrical protection of the device should not be worse than IT24.

Here is a simple example. In winter, when working batteries, warm air rises up and accumulates around the ceiling, while cold, on the contrary, lowers down. Including the fan, we force the warm upper layers to "stalk" and increase the total temperature of the working area (parts of the room most actively used by people). The working volume of the room is made out: 50cm from walls and window openings and from 10 to 180cm above the floor. By the way, for the most efficient work, the "turntable" should be directed to the floor or ceiling (after all, the main task of the simplest fan is mixed with vertical air layers). The perfect option is to suspend the device of this kind to the ceiling, as is done in stores and offices.

Fans, mixing air, are indispensable in rooms with elevated temperature and humidity (for example, in bathrooms). In this case, the constant air flow does not allow moisture to condense on solid surfaces.

Vertice. Ariante lamp fans can be used as an additional light source. And yet, no matter how miles are "Motors with a propeller", they are unsuitable for solving "global climatic problems". If you really have an acute problem of the ventilation of the apartment, you will have to use much more serious and expensive devices.

To ventilate individual rooms (kitchens, toilet, beloved greenhouse or gym), the exhaust installation is best adjusted in the wall or window. This is a rather complex mechanism equipped with a check valve (which does not allow air to return to the room), humidity control system and timer with the possibility of programming the operation mode. Built-in installations of Xpelair, Silavent, Manrose (United Kingdom) and S P (Spain) differ in the main ways of installation - there are wall, ceiling, window, roof, intracanal models.

What is worth paying attention to, choosing a fan? The main characteristic is the performance, measured in cubic meters per hour. What should be this indicator for your particular room? Find the answer is easy. It is necessary to multiply the size of the room, showing how many times in one hour the air in it should be replaced by fresh. This number (the multiplicity of air exchange) depends on the type of room and is set in the building standards.

Ventilation Device Scheme:

1) bathroom;

2) extract over the stove;

3) ceiling extract;

4) garage, laundry;

5) bathroom;

6) terrace;

7) living room;

8) Fireplace. For example, for a kitchen without natural ventilation with an area of ​​9m2 with a ceiling height, 3,2m will require a fan with a capacity of 93.2 (10-15) = 288-432m3 / h. If you do not engage in the production of buns, and your kitchen is located in a standard apartment building with good air ducts, choose a fan with a salary capacity of about 250m3 / h. Too powerful installation will bring more harm than good, is drafts, excessive noise, excessive load on the power grid and it is not clear why there are spent considerable money. You should not fall into another extremes: with a very weak fan you will simply not achieve the desired result. There is another danger: Suppose you picked up the exhaust system, based on the presence of a natural hood in the house, and then this natural extract took and clogged (such incapsions happen, alas, quite often).

In general, if fresh air is really good to you, it is better to purchase a fairly powerful fan with a humidity control sensor (such products are manufactured by Kanalflakt-Systemair KVK, Silavent Curzon and others). He will order the fan to turn on if the relative humidity of the air exceeds the permissible indicator. These models are economical and, most importantly, make a comfortable microclimate with particular accuracy.

Even further, by the "economic path of development", the English firm DuCEX stepped. Vehicle model A15R is installed in motion sensor: the fan starts work, only when a moving object falls into the "field of his view".

Considering the model offered to you, be sure to pay attention to its noise characteristics. Of course, the most "loud" fan is suitable for the garage. But for bedrooms, libraries, cabinets, class beds, and similar premises, the noise indicator should not exceed 25-30dB.

An example of a wall-mounted edge of the fan with a vertical exhaust company Vortice.If your apartment is equipped with windows-glassware, it is best to get a complex ventilation system. It consists of two parts - exhaust and supply, which are spread as far as possible from each other. The extractor in most cases is placed in the kitchen, and mounted at possible greater height (most often on the ceiling or on the wall of the wall and ceiling). The supply installations are usually located in the bedroom or living room, be sure to be supplied with a noise-residuous device and a very frequent heater of the supplied air (which is especially relevant for our harsh climate).

In the event of a lack of space for two devices, you can use a reversing fan model (for example, HV 230RC from S P). It is capable of working as a hood, then as an air blower. Yes, and is two times less than the "full-fledged" sub-exhaust system.

When organizing forced ventilation, the question inevitably arises: where to give a spent polluted air? Obviously, you can only throw it out into the street. Therefore, ventilation boxes or special holes connecting the system with the outside world are necessary. The ventilation channel device is associated with additional difficulties and material expenditures, so they are always trying to make as short as possible. Extract is cheaper and easier to mount either to the outer enclosing wall of the building (wall-mounted), or in the window (window). The window device is easy to install, but there are often claims to appearance at home. Wall fan is not so frankly striking. The same is the best way to solve the problem - to place the fan and ventilation boxes in space above the falsepotor. For this purpose, some firms produce special particularly flat models (for example, Premiere DX200, Xpelair). Having a thickness of 4-5 cm, such fans fit easily into any types of stretch or suspended ceilings.

KAMP. It is difficult to even call it a fan device, at the same time it: lamp, player, clock, radio and anti-mosquito reel. Exhaust equipment is usually tied to them. But it is impossible to connect to the channels of the natural extract of the device forced ventilation! This should know every resident of an apartment building. WIEM exceptions can be obtained permission to the MVK if you reinforce the request of a bunch of convincing calculations. In general, such extracts for the installation of fans are not calculated, because in this case you will only "spoil the air" with your neighbors (or someone, on the contrary, will ruin it with you). However, in practice, low-power (80-90m3 / h capacity) fans in bathrooms and toilets are a fairly common phenomenon of our life. As experience shows if the ventilation channels in the house are no longer contaminated, they cope with such an additional load.

The device forced ventilation is the occupation of troublesome and relatively expensive. The main thing here is correctly calculated the power of all components of the system and optimally place them in the apartment. This task is only available to specialists. We are not talking about such "trifles" as the inevitable drainage of the walls and conducting a separate power supply line (the installation capacity for an apartment with an area of ​​about 100m2 can reach up to 6-7 kW!). We voluntarily "100% new climate" costs $ 1000-1500. But this is not the limit. If you need not only heated, but also purified from dust and gary air, the price of the ventilation unit will jump to $ 2500-3000 (plus the annual replacement of filters, and this is another $ 300-500).
