For domestic and industrial purposes, hoods, air conditioners and other equipment are used to clean the air. Window fans have not lost their popularity either. Their assortment is varied, so you can find a device for any area of the house. It is a simple and inexpensive way to cleanse air masses. Before purchasing a device, you should figure out what types there are, what functions they perform and how to install them correctly.
Device characteristics and application
A window fan is an indispensable device in cases where it is not possible to make another air conditioning system. Also, due to the widespread use of plastic windows, the installation of such a device is required. Modern double-glazed windows impede natural air circulation, which disrupts the balance and healthy microclimate in the room. The device does not emit noise during operation, which is its important advantage, and also consumes little power.
The positive aspects of installing a window fan include:
- Constant air exchange in the room. The room will be constantly filled with oxygen.
- Replacing bulky ventilation systems.
- The compactness of the device.
- Effective removal of unpleasant odors.
- Profitability. The power consumption for the fan operation is minimal.
- The ability to adjust the operation of the device. For this, a special regulator is used, on which the operating mode can be set.
- High efficiency.
- Reliability.
- A wide range of models for any area and power.
- Price.
- Independence from weather conditions.
- Protection against ingress of dust and precipitation.
- Ease of installation.
The negative sides include:
- The need to replace the glass structure. When installed on metal-plastic windows, the sealing may be damaged.
- There is little noise during operation.
- The presence of heat losses, which can be reduced by using a device with curtains. When the blinds are lowered, the fan switches off automatically.
- If the installation technology is not followed, there is a risk of damage to the glass unit.
The home fan in the window has the following technical characteristics:
- Power. The indicator of the household device is 15-20 watts. Due to its low power, it provides almost silent operation compared to hoods and ventilation systems.
- The average speed of the blades is 3000 rpm.
- Case material - plastic, which is resistant to weathering, temperature fluctuations.
- Operating temperatures are -50 ° C to + 50 ° C.
- The service life is 15 years or more.
Window fans are often installed in basements (cellar, storage). Condensate accumulates in them, which can destroy the structure, therefore, a ventilation system is installed to drain excess liquid. Stagnant air with its characteristic odor will also be successfully removed.
Varieties of window fans
There are three main groups of window fans - domestic, industrial and axial. The latter, in turn, are also divided into three subtypes - supply, exhaust and supply and exhaust.All types differ in properties, characteristics, power, appearance and functionality.
Axial window fans
Instruments consist of a propeller or blade, a housing and a motor. The blades are attached to the axis of rotation. They differ in propeller diameter, number of blades and engine power.
The fan in the exhaust window works with a kitchen hood or independently. It removes unpleasant odors from the room, moisture and excess heat. Consumes a small amount of electricity. There are models with louvers that eliminate backdraft and the risk of contaminated air getting back into the room.
Supply models work on the opposite principle. They let air in, not remove it. The main area of application is oxygen-deficient rooms - offices, living rooms.
Supply and exhaust window fans are a system that works in both directions. They remove polluted air outside and fill the room with fresh air. From both directions, the air flows are cleaned through the filter. The air is also heated to enter the house.
Household fans
These are devices that allow you to ventilate the room without heat loss and the ingress of dirt and dust. The ventilated household fan refreshes the air in the room every two hours and helps to maintain an optimal microclimate.
The positive qualities include small dimensions, low cost, minimal energy consumption, low noise level and ease of installation.
Industrial fans
Large-sized industrial window fans are used in warehouses, workshops, factories. Their installation is foreseen at the stage of construction of the building and takes into account the peculiarities of its use. The devices are powerful, but have a high noise level.
Features of devices
The main distinguishing feature of window fans is their low power consumption. But this does not negatively affect their functionality - they also effectively remove polluted air from the room.
With a simple design, window fans have a high level of efficiency and create a minimum of noise. They are easy to install even with your own hands. The functionality is not affected by the environment, the devices operate at sharply positive and negative temperatures. To prevent the cold from entering the room, you can buy a fan in the window with curtains.
Selection recommendations
A wide range of models is associated with the ability to use a particular device in a variety of operating conditions.
Before choosing a device, you should familiarize yourself with the information on the appropriate power. Powerful fans are usually installed in industrial premises. A small device is enough for an apartment.
If you choose a hood for a kitchen window, it is important that the fan effectively removes odors that appear when cooking food. The best option would be a high-power supply and exhaust or wall-mounted air exchanger. In addition to it, an extractor hood and an additional air outlet are installed in the kitchen. It will help cleanse the kitchen space of excess heat and burning.
Bathroom and toilet are rooms with high humidity, where the risk of mold and mildew growth increases. It also requires the removal of an unpleasant odor from the bathroom. The best choice is a wall fan, which is installed together with a non-return valve. Often the system is connected to lighting. When the light is on, the air exhaust will work, and when it is turned off, it becomes inoperative. This scheme is simple and efficient.
A supply window hood is usually installed in a room or hall. It is enough for small premises.Many experts advise installing the supply and exhaust fans at the same time to maximize air exchange. Then the room will be constantly filled with oxygen, which will help a comfortable rest.
Installing a window fan
Features of the installation of a window duct depend on the type of window. General algorithm for installing the hood into the window:
- Checking the health of the shaft in the room where the device will be placed.
- Marking the window for the duct.
- Cutting holes. In the case of metal-plastic windows, professional help is required.
- Fastening the frame on which the equipment is placed.
- Duct connection.
- Electrical connection.
There are two ways to install the fans, which depend on the type of glass units. The first method is used if the house has single or double glass plastic windows, as well as old wooden ones. To put the fan, you need to remove the glass, cut out a hole in the shape of the fan, put it back and place the device.
In the case of installing metal-plastic windows in the house, a more complex method is used, since it is important not to damage the sealing of the double-glazed windows. In this case, the installation is carried out by specialists who remove the glass and put in its place a new one, with a pre-cut hole for the fan.
It is important to install the device correctly. Otherwise, there may be a lack of air flow or cold entering the house in winter, vibration and noisy work. If such problems are found, the system should be reinstalled.
