Forced ventilation in the apartment: the types and installation of the system

The presence of ventilation in the apartment building makes a person's stay comfortable. Such a system can be forced, natural or mixed. What kind of a choice, you can decide, depending on the features of the building and each room that needs constant air renewal.

Forced ventilation in the apartment is considered the most effective, with its help you can achieve the removal of exhaust air and fresh air, while oxygen can enter separate rooms or the entire apartment. To create such a system, it is necessary to purchase appropriate equipment, which must cope with the renovation of air in a room of a certain area.

Why choose forced ventilation?

Forced ventilation in the apartment has certain advantages over alternative solutions. This includes the ability to adjust the power of the system, quiet operation of the equipment, as well as ease of arrangement. You can buy systems that will be equipped with a functional that is able not only to update, but also to heat the air in the cold season. To implement such an idea, it is not necessary to have special skills, but some attention should be paid not only to the choice, but also to the place of installation of equipment. Such a system is considered topical if the windows are made of plastic, through which fresh air can not penetrate.

Due to the fact that apartments are most often restricted in free space, it is recommended to select devices of compact size, which can be controlled using the remote. As an additional advantage of such systems, there are check valves in almost every unit, so that the exhaust air does not return back to the rooms, and when the equipment is switched off, no air is introduced.

Types of forced ventilation

If you chose forced ventilation in the apartment, then one of the existing systems of this type can be installed. This should include the exhaust design, supply and supply and exhaust equipment. The first version works on the principle of removing air from different rooms. The supply equipment provides for the injection of oxygen, which has been purified, and also heated.

The supply and exhaust devices act as the first pair of varieties simultaneously. These types of systems are divided into general exchange and local. The first version is used for large and specialized premises and can serve the whole building. To install such a system, it is necessary to create a ventilation project, which in the process of operation will play the role of supply and exhaust. Local systems can be exhaust or supply, their installation is carried out in a separate room. Such ventilation is intended for rooms in which there must be fresh and clean air. The latter in such cases usually have special requirements. In addition, forced ventilation in the apartment can be divided into monoblock as well as compositing systems. Of the individual elements, the first consist, while the second elements are made up of different components that are installed in the building rooms. They can be combined and connected to powerful equipment.

Peculiarities of installation of forced ventilation

When the installation of forced ventilation in the apartment, many people are thinking about what technology to do the work. For this you can do only on your own, as the process is fairly simple. It is important to make calculations that determine the power of the equipment, because it must cope with its tasks. If the apartment has a complete system, then for this purpose it is necessary to plan the trunking, its installation is carried out even at the stage of building the house. It will be necessary to install inlet valves, as well as exhaust fans.

The optimal solution for an apartment is the installation of equipment for a separate room. More often, forced ventilation is created in the bathroom or in the bathroom. Such a system can complement the existing natural extract. For this purpose, an exhaust fan is installed in the ventilation shaft, if any. It will effectively purify the air. In the kitchen there should be a hood that takes exhaust gases out of the room and performs the functions of cleaning oxygen from contaminants, impurities and odor. After the air returns to the room. If the system is created during the construction phase, the design of the ventilation should provide for the installation of a monoblock system, it ensures the creation of optimal humidity and atmosphere in each room.

System Installation Technology

If you install a forced ventilation system in an apartment, you need to understand the technology of work. To begin with, it is necessary to improve the existing ventilation. To do this, additional fans and valves are connected to it. This technique will make natural ventilation a compulsory one. It is important to follow simple rules, the first of which involves drilling holes in the wall, the diameter of which should not be more than 7 cm. With dust, you will be able to handle an open window. On the outside of the pipe should be installed grate, which will prevent the ingress of large debris. Slots are sealed with construction foam. From the inside of the premises, on top of the pipe that protrudes, a box is installed. Before installation, the box is filled with a soundproof material. This technique will partially improve ventilation, but to ensure airflow, it is necessary to install a fan. Its choice is also important. A similar device can be:

• Axial;
• Window;
• Centrifugal;
• Channel;
• Ceiling.

As practice shows, the noiseless and convenient is the centrifugal fan, it can work autonomously, so it is recommended for use in tandem with the air vent system.

Methods of work

If you install a forced ventilation system in an apartment, you will need to follow certain recommendations, they indicate the need to purchase equipment that is useful in the work. This includes plastic pipes, from which the air vent is made. At the next stage, the samplers are assembled for fresh air intake and output of spent air. These elements must be opposite each other. Next, forced ventilation equipment is installed in the common system. The connection of pipes between themselves must be done carefully, making the interfaces leakproof. This is due to increased air pressure when the system is turned on. If the connections are of poor quality, they will simply disperse during operation, air flows will become uneven. This will cause a malfunction in the ventilation.

For reference

Forced exhaust ventilation (an apartment it is needed) is also called artificial, mechanical or supply-exhaust. It is realized only in two cases: when it is problematic to establish a natural system or when all other types of ventilation are ineffective. The forced system is based on encouraging the movement of air flows with the help of equipment. Given that the draft in the ducts depends on the temperature difference outside and inside the building, in hot weather or in areas where heat is most of the time, it is recommended to mount forced ventilation. In this case, it is possible to install an air-conditioning system, and one of the nodes can become a filtration system. This guarantees the supply of purified air inside.

Installing Supply Air Devices

If you are performing a forced ventilation installation in an apartment, you can apply window valves. They are a drive that is located in the upper beam of the window frame. These devices can be installed in any kind of windows, and their throughput varies from 5 to 35 m ³ / h, which is true for automatic mode. The price of such devices varies from $ 20 to $ 25. On sale, one can also find wall channel valves, which are installed in pre-drilled holes. Their throughput is from 20 to 50 m ³ / h, while paying for the device will cost from $ 23 to $ 28. The operation of such installations is based on hygro-regulation. This phenomenon is associated with the properties of the polyamide fabric, which are expressed in expansion with increasing humidity and contraction - with a decrease, this ensures the closing and opening of the valve flap. Fabric elements act as the drives of the entire device.

Installation of the window valve

Forced ventilation in the kitchen in the apartment can be installed. You can do this yourself, for which the sash of the window is removed from the stem of the lower hinge. Then the valve conductor is attached by screws to the upper part of the horizontal profile of the leaf. With the help of a drill it is necessary to make a hole of the desired width and length. The conductor is fixed in the upper corner of the profile of the window frame, in the place where the hole located in the leaf will be located. In the frame it is necessary to make the same hole and fix the window valve to the leaf. The external visor is attached to the frame from the outside, after which the regulator should be switched to the desired mode. The welding is reset. If you will be equipped with ventilation in an apartment with your own hands using the technology of installing a window valve, you will get additional advantages in the form of condensate removal from insulating glass. This problem is quite common for offices or apartments, but it can be solved simply. Manipulations for installing the valve will take about an hour.

Works on installation of a wall valve

To locate such a valve should be at a height of 2 m from the floor surface, near the heating appliances. This is due to the fact that the incoming air flow must be warmed up. Expensive models of such valves may have heating elements. The device has a sound and dust filter, an insect netting, and as a preference to the window one performs better performance. Before making forced ventilation in an apartment based on a wall valve, a hole should be made in the wall, the diameter of which can be from 75 to 110 mm. Independently to carry out such work is unlikely to succeed, as this will require the use of a core drill machine. Therefore, for help, you should contact a specialist. Making a hole with a diameter of 110 mm in a concrete wall will cost about $ 1 per centimeter of the length of the channel. After it is possible to make a hole, it is necessary to install an air duct, the length of which should be equal to the thickness of the wall. On the side of the room is installed a supply-and-wall device, fixed by screws to the wall frame, fasteners are supplied in the kit. From the street in the duct should install a wall visor, and at the last stage the master adjusts the operating mode.

Installing the exhaust fan

Forced ventilation in an apartment with plastic windows may include the presence of an exhaust fan. Since it operates silently and consumes about 12.5-22 W / h, and its thickness is no more than 150 mm, it can be fixed in a wall cabinet or under a suspended ceiling. In order for the air from the room to go out into the street, from the outlet of the equipment it is necessary to hold the air duct through the hole in the wall. The wall visor will cover the outside of the air duct. If you have arranged an economical option, it can be brought to the inflow into the kitchen or the bathroom.

Installation of exhaust devices

Considering the types of forced ventilation in the apartment, which were described above, you can prefer special devices that are installed in the toilet, bathroom or kitchen. For their installation under the fan, an air duct should be placed in the room, an exhaust device is installed in it. Configure the latter is necessary for the desired mode of operation. If the toilet and bathroom are located side by side, then you can use a single air duct to draw the hood in two rooms. It is permissible to use a special tee for the duct system. If we are talking about the kitchen, then we should additionally use a fat filter. Prefering modern hoods, you will get equipment that has several modes of operation. Sometimes in such devices there is a presence detector, which forces the hood to trigger when a person enters the room. If you install ventilation in the apartment, you can prefer equipment with one of several activation modes. For example, the device can begin to work with a change in humidity, with the appearance of harmful impurities such as tobacco smoke or volatile organic compounds.

Maintenance of the supply and exhaust system

Forced air ventilation in the apartment provides for the care of it, for which once or twice a year, depending on the intensity and frequency of use, it is necessary to clean the internal surfaces and filters. In the process, you remove the raid on the grilles and visors with a vacuum cleaner or other suitable methods. It is necessary to wipe the surface of the body and the flap of the device using a damp rag. Due to the fact that the fan is operating from the network, it is necessary to check the condition of the electrical cable and connections. If the operation is irregular, then once a quarter you should start the equipment for 5 or 10 minutes. When forced ventilation is installed in the apartment with their own hands, it must comply with the requirements of SNiP, and the use of additional devices by type of controllers, regulators, timers and sensors will optimize energy costs and extend their life.

Conclusion

The supply and exhaust ventilation in the apartment, house or office can improve the quality of life. After all, fresh air is so necessary for normal brain function.
