Ventilation in an apartment with their own hands

The apartment was too stuffy, the windows began to fog up, and the characteristic kitchen and toilet scents for a long time remain in the premises? The reason for all the troubles is one - insufficiently effective ventilation.

This problem requires an early solution. Otherwise, you run the risk of saying goodbye to wallpaper, furniture and other items of apartment arrangement, which will simply begin to rot in conditions of excessive humidity.

It is possible to equip an efficient and reliable ventilation system in the apartment on its own. To have any specialized skills to perform such work is absolutely not necessary - you just need to have basic knowledge on the conduct of relevant activities and be able to work with basic building tools.

Read the presented manual, do everything according to the recommendations given, and you will forever forget about the problems that arise in conditions of inadequate ventilation of the apartment.

Ventilation requirements in the apartment

Bquently with the applicable sanitary norms sufficiently considered such ventilation at which each room exhaust air is completely replaced by fresh at least twice per hour.

Initially, ventilation is supplied to each apartment from a common ventilation duct. However, in some situations, the power of such a system is insufficient to provide the required level of air exchange.

It is not necessary to call specialists to check the efficiency of the ventilation system. You can take elementary techniques and draw conclusions about the quality of air exchange yourself.

Checking the ventilation before starting work

Start checking the functioning ventilation system. As a result, you determine why ventilation does not work as it should.

Start with a basic check of the hood with paper. To do this, take a strip of newsprint about 3 cm wide and about 15 cm long, bring it 5-6 cm to the ventilation vent and observe the behavior of the paper.

Under normal conditions, the paper will tilt towards the exhaust port.

It is strongly recommended not to use lighted candles or matches to check the effectiveness of air exchange. Flammable gases may accumulate in the ventilation ducts. This happens very rarely, but you can not ignore such a possibility - careless handling can lead to disastrous consequences.

If the paper does not deviate, or if it hardly moves noticeably, there is something wrong with the ventilation.

Next you need to establish what exactly the problem is. Open the windows and doors, and then repeat the test using a paper strip. If the paper began to noticeably deviate into the ventilation vent - with the moves all right. In the absence of any changes, you can conclude that the clog is in the channel.

You need to get rid of blockages. With cleaning channels can also be handled on their own. The following guide will help you in this.

Cleaning the channels

Begin an individual check of each vent. If the paper behaves differently, the contamination is present in the inner boxes.

To eliminate such trouble, it is enough to arm yourself with an ordinary dish brush attached to a flexible and thin steel cable, and walk through a similar construction on the vent.

You can get rid of debris by using a vacuum cleaner with a long tube. For example, you can connect a long piece of an ordinary flexible hose for irrigation. Such an article has the required flexibility and is, at the same time, quite rigid.

If, as a result of the above measures, you did not find any clogging, then the problem is at the level of the main ventilation stroke. Its cleaning is done in a manner already familiar to you, you just need to take a larger ruff. In addition, you may need other accessories, for example, fiberglass rod, metal or wooden rod, hook, etc.

Be extremely careful while cleaning the main ventilation stroke. They often build their own wasps nests and other dangerous or extremely unpleasant animals.

Consider also the fact that in most cases tenants of apartment buildings are forbidden to climb on their own to the main ventilation course - it is the responsibility of the organization on whose balance the building is located, or the owner. Therefore, it is better to immediately apply to the appropriate place in order to avoid further unpleasant proceedings and not engage in the performance of extra work that is not part of your duties.

Ventilation System Installation Guide The following manual will discuss the procedure for self-installation of a simple ventilation system consisting of a supply air valve and an exhaust fan. Having gained experience, you will be able to mount more complex air-exchange complexes yourself, but for now, read the instructions and follow it step-by-step.

Installation of supply ventilation valves

Traditionally, the valves are installed above the heating batteries in the space to the window sill.

The operation of the valve is based on an extremely simple scheme: through the pipe, the air enters the valve. Due to the close arrangement of the valve to the fan, the air will be heated when passing the battery to an acceptable temperature.

The design of the valve is designed in such a way that air enters the room without any dust particles.

The order of arrangement of the supply valve

The first step. Drill a hole in the wall with a diameter of about 60-70 mm. Drill in such a way that the hole has a slight downward slope, otherwise moisture will enter the room.

Before starting work, open the window. Otherwise, only the created hole in the room begins to tighten the dust.

The second step. Insert a suitable pipe into the finished hole. The outer end of the tube should be flush with the surface of the wall, and already within the room protrude approximately 10 mm.

The third step. Fill the free space between the walls of the drilled hole and the tube with mounting foam.

The fourth step. Attach a box from the kit to the wall. For fixing, use dowels.

The fifth step. Insert the sound-absorbing material from the kit into the box.

Step six. Close the installed valve with the front cover.

To ensure a sufficient and uniform flow of pure oxygen, these valves must be equipped in each room. One valve is capable of providing fresh air in an average of 30-45 m3 per hour. One person for normal life needs 30 m3 of air per hour.

With the above data, you can set the required airflow and the right number of valves specifically for your housing.

Assembly of the exhaust fan

For maximum efficiency and productivity of the ventilation system, install modern exhaust fans in the bathroom and kitchen. For today in specialized shops there is a wide choice of such devices with various characteristics.

To determine the appropriate power of the exhaust fan, you need to multiply the room volume by 7 for a bathroom, multiply by 10 for a kitchen.

For installation in a bathroom, it is best to purchase a unit equipped with a humidity sensor. Such a device will automatically start up when the humidity level of the air rises above the permissible value.

The exhaust fan with preset timer is suitable for the toilet. Thanks to the timer, the unit will automatically turn off after a short time after start-up.

For installation in the kitchen, try to find a fan model equipped with a grid. Thanks to the grid will be excluded the possibility of penetration into the room of all kinds of insects and debris. Such grids are easily removed and washed with ordinary water.

If you can not find the exhaust fans described above, or if you can not buy them because of a lack of sufficient cash, buy an ordinary model. In the bathroom the fan is recommended to be connected directly to the switch - as a result, the hood will be started together with the inclusion of light.

fan Installation of the unit is carried out according to the instructions, nothing complicated in this. It is usually enough to simply attach the case and accessories to the wall with the help of self-tapping screws. In general, follow the recommendations of the manufacturer of your chosen fan model.

fan To further improve the efficiency of air exchange, it is recommended to create 1-1.5 cm clearance between the floor and the lower edges of the interior doors. Such gaps are necessary everywhere, except for bathrooms. To mask the gap, you can install a special decorative perforated panel or mesh.

Now you have the information necessary for the self-adjustment of simple supply and exhaust ventilation. Follow the recommendations received, and you will forever forget about the problems associated with inefficient air exchange.

Good work!
