Ventilation in the bathroom and toilet, forced ventilation by one's own hands

We used to monitor the quality of the food we eat and the water we drink. However, few people pay enough attention to the air we breathe. Meanwhile, clean air is also important for our body, like water and food. With the constantly deteriorating ecology and ubiquitous gas contamination of large cities, banal airing of premises will not work. In such conditions, the best way out is to install ventilation.

Clean air and lack of harmful impurities in it are needed to prevent the occurrence of headaches, drowsiness, dizziness, as well as for the prevention of allergic reactions.

In the bathroom, ventilation is as important as other rooms, and perhaps even more. The fact that the bathroom constantly accumulates steam and moist air and it is moisture that most contributes to the appearance of mold.

Mold can settle in the lungs and lead to serious respiratory diseases, triggering the development of asthma, allergies, etc. It is harmful not only to the human body, but also gradually destroys all objects and materials, but which is formed, right up to the concrete. Therefore, the installation of a normally functioning ventilation system is not a whim, but a necessity.

According to this document, rooms require artificial ventilation in the event that, due to air pollution or environmental conditions, the required sanitary standards are not met due to lack of natural ventilation or if simple ventilation is not enough.

The permissible level of dust and harmful substances in the air is prescribed in the sanitary-epidemiological rules. So, in terms of carbon dioxide, the maximum allowable amount of carbon dioxide in rural areas is 650 mg / m3, in small towns - 800 mg / m3, and in large cities - 1,000 mg / m3.At the same time, the rate of air exchange per person is 28 m3 / h. Excess carbon dioxide can cause shortness of breath, dry cough, runny nose and other negative consequences for the body.

The most common types of ventilation are allocated depending on its purpose. So, it is singled out:

• Extraction ventilation , which removes exhaust air through the exhaust ducts. Such ventilation is convenient to use when possible to combine natural and mechanical ventilation.
• Supply ventilation , which by adding fresh air creates additional pressure, displacing the exhaust air.
• Mixed type ventilation , which combines both operating principles.

In addition, there is a ventilation often divided into natural and forced.

• Natural ventilation is the ventilation that is initially designed and installed during the construction of the room. The most typical scheme for ventilation of the bathroom and toilet in apartments and apartment houses is a scheme in which the bath is connected to the toilet by means of a vent, and from the toilet the air is vented to the general ventilation duct of the house.
• Forced ventilation is ventilation, which is installed by the owner of the house at will and which implies the use of a hood or fan.

Check the operation of your ventilation system is much easier than you think. You will not need any additional tools. Simply light it and bring a burning match or a small scrap of paper to the grille. If the flame fluctuates, ventilation works.

Another way to check the operation of ventilation is that you will need to arrange a draft in the room, opening the window and door in the bathroom, and attach a scrap of thin paper or, for example, a napkin to the ventilation grille. The napkin should also either adhere to the grill if ventilation normally takes the air in, or it must be blown off the grate by the flow of air coming from the vent. If the napkin just drops down - it's time to change the ventilation.

In private houses, individual ventilation ducts are usually designed for each room separately: for the kitchen, bathroom and toilet. With the help of the extractor, the exhaust air through such channels is discharged to the roof.

In multi-family houses, a typical ventilation system is usually used in which all ventilation channels are combined into one common channel that opens onto the roof. The ventilation is based on the thrust arising from the temperature difference.

In case of forced ventilation, special ventilation systems are installed with sensitive elements that open and close the shutters as needed.

There may be several reasons why your ventilation system may not work properly:

• Errors in the planning of the entire building's ventilation system: both during calculations and directly during installation.
• The accumulation of various debris in the ventilation ducts.
• Damage to the ventilation system of neighboring apartments, for example during repair, which caused a disturbance of the flow of air in the ventilation.

As a general rule, when installing a fan, the following parameters must be observed:

• Low noise level with fan running( max. 30 dB);
• Sufficient distance from electric heaters;
• High-quality insulation of electric wires in high humidity conditions;
• The capacity of the fan used should be chosen taking into account the area of ​​the room and the number of people living in the apartment;
• Complete change of air in the room should occur at least five times per hour.

The basic types of fans:

• connecting to the switch and working when the light in the bathroom or toilet is lit;
• equipped with special sensors, and automatically turn on when the permissible humidity level in the room is exceeded;
• equipped with a timer, in which you can independently adjust the time of its operation.

In addition, the fans differ in their design features:

1. Axial is the simplest model. They are also called propeller.
2. Radial - provide high pressure in the room. They can have straight, tilted back, curved back and curved forward blades.
3. Diagonal - a mixture of axial and radial fans.
4. Diameter fans can operate with large volumes of air due to the fact that air flows pass along the entire perimeter of the impeller.

You can mount the ventilation yourself. Of course, it is better to do it in the house under construction, however, and to conduct ventilation again is not too difficult.

• First, check the vent channel. It will need to be cleaned of debris. If you can not connect a new fan to an existing channel, you will need to purchase several meters of a new air vent and lead them to the old channel.
• Determine the location in which your fan will be placed. The most optimal location for the fan is the wall opposite the door.
• Mount the fan in the vent hole, if necessary, widening the opening to the desired diameter.
• Carefully route electrical wires from the fan so that they are minimally exposed to moisture and not visible.
• Connect the fan to the switch.
• Fasten the fan and its grill either to liquid nails or to self-tapping screws.

As a rule, the vent channel is located in the toilet. There are two ways to organize ventilation between the toilet and the bathroom: either lay a separate ventilation pipe from the bathroom to the air vent in the ceiling area, for example, or install two separate fans: one in the wall between the bathroom and the toilet, and the other in the toilet, to the vent.
