Ventilation in the toilet and bathroom: how to make your own hands

click fraud protection

Toilets and bathrooms are in need of additional care, including ventilation. The apartments and houses bathrooms equip extracts, to which is supplied the ventilation pipe. In rare cases, the toilet / bathroom can be a window. Organized by the natural ventilation provided unless the doors to open. Bath is a fundamental point, because excess moisture harms furniture, door leaf and electronic devices in the room. The toilet role of ventilation is reduced mainly to the elimination of odors and harmful effects on harmful microorganisms. Wall fans for bathrooms provide inflow of about 10 m³ per cubic meter per hour. For ordinary enough 6-7, while combined with toilet - 8-10. To qualitatively improve the ventilation in the bathroom and the toilet have to gain access to the empty space behind the walls.

Features - what is needed ventilation

Man breathes more carbon dioxide than it consumes. The resulting compound was stored in a room and breathing becomes difficult. In addition, the body loses heat, moisture, and produces a variety of products through the openings in the skin. During the summer, because it becomes stuffy, and the smell in the rooms is deteriorating. High level of integrity aggravates the situation. Natural and mechanical ventilation improves air condition and eliminates the problem. human health will not be detrimental oxygen lack (hypoxia) and the room will be suitable for long hanging. Ventilation is very relevant in the case of pets, because they are much shorter and are precisely where most of the accumulated carbon dioxide. the flow of oxygen has beneficial effects on hygiene: the fungus becomes more difficult to develop, and the timely ventilation ensures that no harmful microorganisms. It is increasingly important for bathrooms.

Bathroom ventilation

types of ventilation

No matter what the room may belong ventilation, it is natural and forced. The bathrooms and toilets available both natural and artificial methods. In the first case through a ventilation hole is made in the form of hoods with the lattice, with or without a vent pipe. Second - it is a mechanism with vanes, exhaust fan over the protection grille. For bathrooms buy including noiseless ventilators with a partition, which reliably conceals an inner part of the flow of water ingress. For areas larger 4-6 m² organize 2 point ventilation and be sure if bathroom toilet. In the room you can put an ordinary paddle fan, or at least do two extracts at different points. Recent are wall and ceiling. In a modern design of the second embodiment is preferable.

Bathroom with mechanical ventilation

natural

The natural form of ventilation means air exchange between the room and the external environment. Since the pressure inside buildings below, due to the difference gaseous mass will move in a direction from outside the room. If open windows, vents or transoms, the method of natural ventilation is considered to be unorganized. The other, an organized method, provides operation and the flow of exhaust openings. The ventilation paths using baffles to reduce the pressure. As for modern window systems, they are equipped with regulators clamp the valves and rotary mechanism to move to the "micro-ventilation" mode. Manufacturers rarely provide vents and typically limit the design of 2 valves. The last opened in 2 different planes. For the comfort ventilation in the evening in the systems provided mosquito nets. Window openings have only a small amount of bathrooms and toilets.

Natural ventilation in the bathroom

Forced or artificial

Artificial (also forced, mechanical) ventilation - the movement of air masses as a result of the fan or ejector. Efficacy forced embodiment is based on further purification, temperature and humidity regulation. The designs for mechanical ventilation is used, in fact, themselves fans, precipitators, air heaters, silencers and electric motors. Devices distilled air over a long distance. Qualitative fans have the ability to locally remove the right amount of air for any changes in the environment. Content fan is cleaned, heating, cooling, humidifying or ionization. In this case, the cost of electricity to power devices reach high values, and to pay for it can basically enterprise.

Variety of devices for artificial ventilation:

  1. fans;
  2. Aerogivery;
  3. ventilators;
  4. Ionizers.
Forced ventilation in the bathroom

Main specifications and requirements for the installation and ventilation organization

One of the criteria concerns fresh air for one cubic meter of bathroom / toilet per hour. For both rooms is - 6-7 m³. For combined options - 8-10. Ideally oriented to the performance of 20% more. If the vents in the bathroom alone, it must be the supply of type. The principle of operation is checked with a lighter if the flame moves away from the hood - the unit of the supply, and if it is approaching - hood. In the wall or window valves, if any, have to be air purification system. All the rules and requirements are in SNIP 41-01-2003. According to them, if there is no air pollution and natural ventilation, and therefore are not met health standards, the required artificial ventilation. Incoming air at Norm 1 is 28 m³ / hour.

Permitted concentration of carbon dioxide is equal to (mg / m³)

  • in rural areas - 650;
  • in small towns - 800;
  • in big cities - 1000.
Organization of ventilation in the bathroom

Design Features

The decision on the form and structure of the ventilation takes the designer, in accordance with SNIP. Configurable reduced to 2 solutions: circular and rectangular. Take into account the particular structures and targets of the room. The design of ventilation will be part of a particular type of local or general dilution, supply, exhaust, or mixed. For ventilation of living rooms, offices, shops need different parameters. The advantage of rectangular versions - compact, easy installation and the possibility of laying planned on a complex trajectory. Air duct can be hidden even in the false ceiling. Existing SNiPy allow difference of width and height of the channel 4 times in favor of the first indicator. Round air ducts - a high throughput. The level of resistance in a duct below.

Bathroom ventilation rectangular design

rectangular

Rectangular leaves many options for installation and use of construction volumes. Normal operation is possible even with suspended ceilings. The basis for calculating the amount of space charge that tenants are willing to sacrifice. If important every free portion rectangular design would be the only option. In terms of aerodynamics and noise reduction system with a rectangular cross section significantly inferior circular analogue. The corners also accumulate more dust. Thus, a round rod designs do not change with time as well as rectangular. For this reason, in systems such as aspiration rectangular cross-section is not used. Cleaning and caring for round systems take less time. In turn, because of the cost of the flanges 1 m² rectangular system turns up. Efficiency and preferred embodiment, depends on the characteristics of seals: the smoother will be twists and turns, the better - ergonomics.

Rectangular ventilation in the bathroom

round

According to the cross-sectional area of ​​such structures take more height space. In this case, if the object parameters allow the round system would be the best option. In her work there is less noise and air movement experiences a slight resistance. As a result, the whole system works efficiently and economically in terms of energy consumption. In this case, not only reduces operating costs, but the initial capital investment: need smaller sizes. Additional criteria - the interior, but sometimes it becomes even crucial. The fact is that to hide a round air duct will need more space. Sometimes this leads to excessive loss of volume of the room, sometimes - to poor design. Outdoor seating, in turn, greatly spoil the facade of the building, which is not the case with a rectangular design.

Round ventilation in the bathroom

How to choose

The available range includes a large number of models. Bathroom and toilet allocated 5 criteria from which to draw on. First - this is the diameter of the air in the room. blower nozzle is a standard modifications indicators 100, 125 and 150 mm. The second factor - the presence / absence of air ducts in the room itself, as well as their location. The third parameter, the power affects the compatibility with a particular bathroom, depending on the area and type. Another criterion - protection against moisture. For him, identified IP marking. Sanitary assembly required model of IP30 or higher. Ideally you should spend the extra money and purchase option IP44. He will be in a hermetically sealed housing with protection against splashes. Another detail is the level of noise. If the exhaust system makes no noise in the bathroom will be much more comfortable.

there are models with intelligent control Among the ventilation systems.

Selecting ventilation for the bathroom

Materials and components

Ventilation ducts harvested from a rectangular or circular cross-section. In most cases, it is made of plastic or metal. In small bathrooms and toilets fan is in a hole in the wall. In private houses the ventilation system is collected from the air (especially the ceiling) - this is usually tube of 2.1 and 0.5 m. In this arrangement, the fan itself is embedded or trim device. The first subtype used in complex branched systems. Overhead used to work in the same room. Included with the system are rectangular horizontal and vertical rotary knees. Lots ventilation bonded couplings. Check valves, in turn, prevent the ingress of insects and air. Typically included are four plugs for external fixation.

Accessories ventilation

self installation

It is carried out in 4 steps:

  1. Preparatory stage;
  2. Choosing the installation site;
  3. Selection of wiring diagrams;
  4. Directly install itself.

First, preparatory work is carried out. The first step is comparing the diameter of the exhaust device and the size of the mine - to make sure that the measurements were correct. In which case will help or corrugated plastic tube and vacuum sealed with foam. Narrow opening, on the contrary, are expanding punch. Another point - the place of installation. In the bathroom you need to fix first the hot moist air, so is the ideal point opposite the door and at the top of the wall. In a separate toilet seat principle irrelevant installation. The bathroom / dressing room with his hands algorithm installation includes 5 items. First, remove the front cover. At the portions where the fan is adjacent to the wall, causing liquid nails, silicone or a polymeric adhesive. The device is then inserted into the electric motor and impeller with blades inside - completely hiding in the wall. Housing tightly pressed and wait until the glue grabs. Then set the mosquito net, if it was included. At the end of the front cover is fixed with dowels or screws, and then run the cable and connect the device to the network.

you should use the terminal blocks, and not "twist" for the connection of wires!

Installation of ventilation in the bathroom

Diagnosis ventilation state

Changes in the bathroom begins with diagnosing the state of air ducts. To test rods used paper, lighter or lit match. The paper supply systems and the flame must move away from the ventilation and exhaust - approach. In any case, the movement will be marked with the correct operation of the channel. Improve traction possible after a complete check of the ventilation pipe. After the repair work could have stayed there the trash. Traction purging channel then checked twice with a closed and open door. During installation, errors are possible that are sure to appear on the system. We are talking about the difficulties in the movement of air due to improper installation, excessive noise of the fan, tightness of the mine compound. Noise can interfere even in the living room if ventilation pipes pass through it.

Rules and instructions for operation of the exhaust system

Need regular maintenance in order to prevent damage: with the passage of time on the blades accumulate dirt and dust. For this reason, the unit can not operate at full capacity, and at some point will fail. Simple preventive measures include inspection for clogging and cleaning blades. Operate the ventilation system can be at the same time everyday moisturizers, cleaners, ionizers, air conditioning. In a decentralized system, mechanical ventilation with heat recovery eliminates air permitted association with a kitchen bathroom ventilation. Under no circumstances may the combination of the exhaust air duct to the bathroom or toilet facilities for parking or utilities flue. Normal operation of the ventilation and air-supply and exhaust system is possible at a room temperature not below +18 ° C.

Operation of the exhaust system in the bathroom

conclusion

Ventilation systems are distinguished by the five categories: a method for prompting movement destination, Circulation organization, design characteristics and section. It is natural and forced, exhaust and fresh air. In addition to this - the center, the local, the alarm and smoke. By design - channel and channel-free. sectional shape, in turn, is rectangular and round. For bathrooms are characterized by high humidity and sudden temperature change, so that the microclimate regulation will come in handy. pick intake channel options for placement. But the choice of the form - a complex and comprehensive. Before purchasing and installation should explore building and sanitary standards, harmonize the size and determine the installation location. Thereafter, the wiring is selected and produce fastening. From time to time you need to channel diagnostics.
