Problem removal unpleasant odors It is facing many residents of megacities. Especially it is relevant in old houses with natural channels. As part of today's review, we will look at silent channel fans for exhaust, analyze their views and advantages / disadvantages. Alongorally, we will deal with those technical characteristics to which you should pay attention to, and tell you how to install such a fan correctly and, if necessary, repair. And completing our story review best models channel fans.
In the phrase name, the two term subsection, which should be disassembled. This is a "channel" and "exhaust". With the second, everything is easier. That is, the device must be installed on the exhaust portion of the ventilation system. In order to be clear what we are talking about, explaining that the ventilation works on the principle of caring the air masses and the same amount of inflow. One without another does not exist.
Fans can be installed on or on exhaust. More often use precipitation models. By the way, these devices include roof fans or centrifugal "snails", installed on the street.
Channel aggregate is a completely unlike them design. It is a cylindrical shape, inside which the fan is mounted. That is, the device itself can be a continuation of the duct ventilation system Or it can be installed in the body of the wall, or rather into the through hole made in the wall. More often such models are called air, but no matter how they were called, the essence remains one - air exhaust with the fan.
Now we'll figure it out why such fans are called silent. Any equipment in which the rotating parts makes certain sounds associated with the formation of vibration. The fans have another reason to make noises - this is a flow of air that passes by inner space instrument.
Attention! Snip 23-03-2003: CH 2.2.4 / 2.1.8.562-96 The noise level inside the residential premises should not exceed 35 dB. For comparison, you can bring several noise levels.
It is under the amount of 35 dB and the noise level of the working device is adjusted. This is achieved in several ways:
All this in the coupe creates conditions for silent operation of instruments. Their noise level does not exceed 25 dB. That is why they got their name.
Mostly silent or bathroom are divided into two categories:
In the first case, two groups: with a circular cross section of the case and with rectangular. In the second, these axial fans, radial and centrifugal. Channel fans for round air ducts are most often used in private house-building. But there is one point here, which determines the installation location.
For example, very often the exhaust portion of the ventilation system is a vertical pipe (usually plastic or concrete), which permeates the structure from to the roof. Hiding such an air duct into the walls in the construction process or build it in the form of a separate box. Install the channel fan can not be installed. Because when the device fails, it will not be possible to repair or replace. On such an air duct you can put the roof model. Duct devices are mounted in the ducts that remain outside the designs of the building. For example, collected in the attic.
As for rectangular aggregates, they can be attributed to the group of industrial fans for exhaust. But this does not mean that they are not used in the residential house building. Rectangular shape ducts are used in residential or office buildings. The photo below shows one of the models made of plastic. This wall or ceiling type is a device with a rectangular case. Pay attention to its blades, this is a centrifugal fan. He has a blades located along the direction of the air flow.
An axial model or axial is a device in which the direction of air movement corresponds to the location of the axis of the electric motor. The impeller is attached on it. It was this design that got a great use in everyday life, because:
Attention! The axial fans themselves are silent among all models used.
The principle of operation of these devices differs from previous ones that the movement of the air masses does not occur along the axis of the electric motor shaft, but with a slope, depending on the slope of the impeller blades. They can be tilted back or forward. Accordingly, the fans are mounted on the influx of air, with a reverse extract.
But the slope affects not only the flow direction. There are other characteristics:
| Form of impeller | With bent forward with blades | With bent back |
| Kpd. | 0,7 | 0,8 |
| High pressure work | 0,9 | 0,8 |
| Working with air in which there are mechanical impurities | 0,2 | 0,5 |
| Explosion safety | 0,6 | 0,5 |
| Silent | 0,8 | 0,9 |
| Controllability | 0,2 | 0,1 |
Exhaust channel fans for the kitchen or bathroom are generally radial models.
The centrifugal tube exhaust fan is a novelty that appeared on the market relatively recently. But she ranked firmly. A distinctive feature of this type is an impeller with blades that are located longitudinal axes and do not have a slope in the longitudinal plane. They have a bias in the transverse plane.
The devices were obtained only by the fact that in the process, the rotation of the impeller blades discard the air towards the body of the apparatus, where the zone of high pressure is formed. And in the center, on the contrary, zone reduced pressure. That is, there is a sharp movement of air from the center. It is the difference in pressures inside the case creates the conditions under which outer air Begins to suck inside the aggregate.
And another one distinctive feature - This is a special collector that performs the functions of the diffuser. Its design helps facilitate air suction inside the fan.
As mentioned above, the design of channel fans is a housing, inside of which an electric motor is installed. On the shaft of the latter fastened the impeller. Corpus has cylindrical shapeBut the length of the cylinder can be quite large relative to the diameter or not very large. First include models that are mounted in the walls. To the second, which are installed in the air duct systems.
The first is supplied with two decorative, which are installed on the surfaces of the walls located on different sides. The second are attached to the air ducts with special collectors on the clamps that are supplied with the fan. The latter are usually sold assembled.
Some models are supplied with check valves that do not give air with non-standard situations to move in reverse side, that is, in the premises of the building. It is necessary to pay tribute to the fact that although the exhaust fan with the check valve is more expensive, but it protects the inner rooms from the irregular operation of the ventilation system. For example, summer, heat, the fan "got off" for some reason. If the temperature inside the house is lower than on the street, the air will begin to move in the opposite direction. Check valve This will not give it.
Like all devices of this type, channels have one basic characteristic: power (performance). Or rather, the amount of air that passes through the device per unit of time. Usually, cubic meters passing in one hour - m³ / h.
This indicator depends on the two parameters:
In addition, it is necessary when choosing to pay attention to other quality instruments. Namely:
You cannot choose this option to choose. Because it will depend on the required air exchange indoor. If the conversation is about the overall ventilation of the house, and not about a particular room, then you will have to fold the values \u200b\u200bof the air exchange of all rooms at home. This will be the performance of the fan.
For example, a house in which the total living area is 100 m², the ceilings height is 3 m. The air exchange will be equal to the size of the room, that is, 300 m³ / h. It is necessary to add a toilet air exchange and a bathroom - 25 m / h and kitchen 60 ÷ 90 depending on the type and. It turns out:
300 + 25 + 25 + 70 \u003d 420 m³ / h.
This is the performance of the fan.
The basis of the marking of the fans of this type is the diameter of the input and outlet. The size of this parameter: 100 mm, 125, 160, 200, 250, and 315. The channel fan for the exhaust 100 and 125 mm belongs to the discharge of household. Channel fans 160 and 200 mm are more often installed in restaurants, cafes, shops of a large area and other places. The rest can be attributed to industrial models that are mounted in the system of aircraft production workshops. All of them work from electricity network in 220 V.
For example, we will analyze the instruments of the WCC brand (channel fan round cross section) In the photo and the table below shows its dimensional parameters.
From the above, the photo shown can be concluded that the device itself is selected by the diameter of the duct. For example, if the exhaust fan is installed in a system of 100 mm with a diameter, then the air duct must be that size.
Attention!The distance from the knee to the inlet nozzle should not be less than one diameter. In the case of 100 mm silent channel fans, this distance should not be less than 10 cm. The distance from the output nozzle to the removal or fitting should not be less than three diameters.
If the conversation is about the devices that are installed in the system of the air duct, the service is rarely carried out, especially if the air is dry and clean. Once every two or three years you can open it and clean from dust. If it turns out, you can try to lubricate bearings. But, as practice shows, this is a matter for professionals.
As for the fans, which are installed in the walls, it is recommended to remove decorative lattices once a year and clean the insides of the cylinder. Everything else is not available.
This is what is not recommended to do ever - this is a repair with your own hands. Usually in the fan fails the motor or condenser. If the first burned, then it will have to replace the new one. And it's not a fact that you will find in the store Motor corresponding to the engine brand.
As for the condenser, if you understand something in an electrician, then you can cope with the replacement. To do this, you will have to measure the parts container. If it matches the passport (designated on the housing) or a little more, then it's not about it. But if the capacity is less, then you have to change. By the way, it is necessary to measure the parameter when the condenser is disconnected from the network with a pre-discharge (closer two ends).
But, as practice shows, high-quality models will serve faithfully for more than a dozen years. And if one great moment there was a refusal to work, it is better to put a new one instead.
