Ventilation cleaning: cleaning ventilation ducts in an apartment building

Verification stage

To begin with, it is necessary to determine why, at first glance, an adequately functioning air exchange system fails. After - determine what needs to be done to intensify its work.

Hold a small piece of newspaper near the vent

(the distance should be five to seven cm from its hole). The end of this device must be drawn into the ventilation by the air flow.

Please note that it is impossible to check indoors with the flame of a candle or a match in any case. This is due to the fact that combustible gas may be in the channel. This does not happen so often, but in this case, no one is immune from negative consequences.

If the verification paper is rejected poorly, or does not do so at all, the verdict is clear: an urgent need to clean the ventilation systems of the room.

Cleaning ventilation yourself: effective ways

In accordance with the current rules for the operation of housing, apartment owners are prohibited from interfering with the operation of engineering and main systems. Cleaning of ventilation ducts is the responsibility of management companies, which can delegate them only to licensed services. But do not forget that "the salvation of the drowning is the work of the drowning themselves."

Self cleaning duct

Each owner should not only know how to clean the ventilation in the apartment, but also be able to do it. The work is simple in nature, and consists of several steps.

In all rooms where ventilation grilles are installed, they are removed. Accumulated dirt, viscous grease and dust particles are removed. I think you should not focus on how to wash them with a detergent.
The area near the hole is processed with a plastic or metal scraper.
To clean the ventilation system, it is better to use a powerful vacuum cleaner by placing the hose in the channel

It is important to "walk" over the entire inner area of ​​the hole.
After completing the cleaning measures, the accessible area of ​​​​the duct is wiped with a damp cloth, the grille is installed in place.

To deal with persistent fatty contamination, it is worth contacting a specialized company. Often, their arsenal of plaque control consists of chemicals that effectively eliminate residual products that cannot be removed with conventional means.

Inspection of ventilation systems before cleaning. Video inspection (television) of air ducts and chimneys

TV inspection is used to diagnose air ducts and chimneys. With the help of a video camera, it is easy to assess the condition of the air ducts, the degree and type of pollution, after the work performed, the quality of ventilation cleaning is assessed. Also, the pipe inspection method is used to diagnose any other pipelines, such as sewers. The study is recorded and provided to the Customer.

Teleinspection of ventilation systems is necessary for:

• determination of presence of contamination of ventilation or chimney with dirt. dust, grease or soot;
• assessing the quality of ventilation cleaning;
• detection of damage, blockage or foreign object in the air duct;
• clarification of the position and nature of the defect;
• assessment of the technical condition of the entire ventilation duct before starting repair or replacement of the damaged area.

Cleaning ventilation in cafes and restaurants

In the kitchens of restaurants, cafes, canteens and other catering organizations, ventilation ducts quickly become clogged with fatty deposits. This is due to the preparation of large volumes of food.In addition, powerful hoods are usually used in kitchens, so air with dust and grease particles actively enters the pipes. As a result, their clearance is significantly narrowed, the efficiency of air exchange can decrease several times. Cleaning the air ducts allows you to restore the patency of the lumen of the channel and completely normalize the air exchange in the room.

Equally important is the performance of the ventilation system in the halls of cafes and restaurants. The comfort of visitors depends on this. If the pipes are not cleaned, then people will be stuffy, and unpleasant smells from the kitchen will spoil the rest and force people to go to another institution next time.

• the appearance of unpleasant odors;
• decrease in the efficiency of the hood in the kitchen;
• stuffiness in the room;
• smog in the smoking room;
• contamination of grease traps on kitchen hoods is noticeable to the naked eye.

Examples of ventilation cleaning work

Specialists of LLC "Ventgazservis" will perform work on cleaning the ventilation systems and return it to full working capacity. Thanks to this, employees will feel comfortable, and visitors will be able to enjoy their rest in the institution, and not inhale unpleasant odors.

Ways to clean ventilation and air conditioning systems

For work related to the cleaning of ventilation ducts in an apartment building, professionals are usually invited.

The fact is that special equipment and special chemical compositions are used for this, especially when it comes to the premises of the lower floors of skyscrapers.

Technological methods of cleaning ventilation ducts can be divided into several types:

1. mechanical cleaning of the air duct cavity;
2. chemical cleaning of the canal using active substances;
3. complex surface treatment with subsequent disinfection;
4. work related to cleaning a small section of the ventilation duct to improve ventilation in the apartment.

Mechanical cleaning of ventilation consists in cleaning the channel from the remnants of construction debris, dust, cobwebs. True, by removing debris from the vertical surfaces and the bottom of the channel, it is impossible to achieve perfect cleanliness - grease and soot still remain on the walls.

The use of chemicals allows you to remove these layers. But you need to take into account that it will not be possible to really make the channel clean without a special foam generator and a rotating brush.

In addition, the foam washes away fat, but it has practically no effect on bacteria and fungi that have eaten into the pores of concrete or brick, as well as on other inhabitants of air ducts - cockroaches.

For air conditioning systems, disinfection is mandatory during maintenance; this method allows you to get rid of bacterial colonies that are dangerous to humans.

Disinfection is also necessary during seasonal maintenance of ventilation systems in residential buildings, it is with the help of special solutions that act on mold, fungi and insects that it will be possible to achieve perfect cleanliness.

Complex processing refers to the use of all methods of cleaning ventilation ducts.

It includes a mechanical method for main air ducts, a chemical method for exhaust ducts with fatty deposits, followed by disinfection of internal surfaces.

In some cases, a significant improvement in system performance can be achieved by cleaning small areas, for example, by removing the grate in the bathroom or in the kitchen and simply removing the accumulated debris from the channel.

Natural exhaust ventilation should ensure the removal of the required volume of air from all the premises provided for by the project at current outdoor temperatures of 5 degrees. From and below….

How to clean ventilation in apartment buildings

By an even flame that does not deviate towards the decorative grill covering the vent, it can be concluded that the shaft is clogged and needs urgent cleaning.

With normal air circulation in houses, the flame leans towards the mine, and in some cases simply goes out.

With this behavior, cleaning the ventilation is optional, but if the last time it was cleaned at least six months ago, it is still advisable to do a little work.

Cleaning ventilation in an apartment building and in production

Cleaning ventilation in an apartment building should be done regularly and much more often than many owners believe. Specific terms are set by specialists after analyzing the condition of the air ducts.The recommended frequency of cleaning is 2 times a year (summer and winter), routine inspection - quarterly.

Ventilation: what, how, why, when and who

At the dawn of mass housing development, each apartment had an individual ventilation duct, which eventually joined the exhaust shaft. Over time, when the houses became higher and higher, horizontal channels began to be arranged between the floors, and already from them to direct the air up to the ventilation shaft.

Ventilation cleaning: cleaning ventilation ducts in an apartment building

The decrease in ventilation efficiency in old houses is, in principle, a fairly predictable process. The main reason is the banal clogging of the ventilation duct, in which debris, dirt, dust and other waste coming from the room accumulate over time. As a result, the outlet narrows and becomes unable to fully process the intake of dirty air.

Periodic inspection of smoke and ventilation ducts

c) in progress operation of smoke and ventilation ducts (periodic inspection) - at least 3 times a year (no later than 7 calendar days before the start of the heating season, in the middle of the heating season and no later than 7 days after the end of the heating season);

Maintenance of ventilation systems

• carry out service maintenance at strictly approved intervals. Do not violate the terms of technical inspection of equipment and manufacturer's recommendations;
• start and stop the ventilation system in a certain sequence (such measures ensure the complete exit of accumulated harmful substances from the air ducts);
• check fan units once a month;
• check the duct heater for leaks once every 2 weeks;
• control the timely replacement of oil when servicing oil filters;
• check meshes and ventilation grilles for blockages once every 3 months;
• control the integrity of the sound-absorbing material.

Cleaning the ventilation in the apartment

Ventilation can be called the lungs of a living space. The benefits of an efficient air exchange system are obvious to any person living in an apartment or private house.

It directly affects the well-being, health and safety of residents.

Regular cleaning of the ventilation in the apartment will ensure a comfortable stay in the house, as well as reduce the possibility of dangerous situations associated with ventilation shafts.

Installation of ventilation and shafts in multi-storey apartment buildings

If an apartment building is not equipped with a ventilation system, all human waste products remain in the premises. Conditions dangerous for people's health and safety of their property are being created. Mold eats into walls and furniture, and occupants suffer from allergies and asthma. In such apartments, babies and the elderly feel the worst.

Frequency of ventilation cleaning

Any technical system eventually fails. An idle ventilation system is a threat to human health. The lack of air exchange with the environment contributes to the spread of infections, the development of oxygen starvation, and deterioration of health.The ventilation ducts are cleaned at intervals set depending on the type of object and the type of ventilation:

• Cleaning of ventilation ducts in an apartment building with natural air exchange is done every 3 years.
• Cleaning of industrial ventilation is carried out more often: about 1 time per month.
• The frequency of cleaning ventilation from combustible waste is 2 times a month.
• Cleaning of air ducts from grease; at catering establishments should be carried out from 1 time per month.

At manufacturing enterprises, the frequency of cleaning process ventilation ducts is determined by responsible persons based on the specifics of production.

Revensis provides services for the repair and cleaning of ventilation in apartment buildings, cleaning of cafe ventilation systems, cleaning of industrial ventilation. We work in hotels, office buildings, shopping centers and other buildings equipped with ventilation systems.

How to wash the hood body

So, with washing the grease filter, we figured out how to properly wash the hood body? After all, it is also covered with a persistent greasy coating, dust and soot.

In fact, all manufacturers forbid washing the case with anything other than neutral products. It is strictly forbidden to use:

• Alcohol-based cleaners, and even more so solvents, as they can tarnish stainless steel or varnish.
• Use aggressive cleaning agents (limescale removers, anti-clog agents, abrasive powders and pastes, grease solvents, chlorine, acids and soda).
• Use hard sponges and brushes.

What then remains? We recommend using dishwashing liquid or laundry soap. The main thing is to prevent moisture from getting inside the case, into the control panel and display.

What are the requirements for ventilation in the house?

If you need to clean the ventilation in the apartment, and you don’t know exactly where to turn, then you can easily use our services. We are in touch around the clock, ready to leave at your first request and implement all the necessary procedures with significant savings in time and money for the client. The reason for calling disinfectors may be the following circumstances:

• after the implemented measurements, there should not be an increased concentration of harmful substances in the air above the parameters of 1000 CO2 cm3/m3;
• the humidity level must necessarily correspond to the parameters of 30-60%, so as not to disturb the normal balance of air exchange;
• air speed should have parameters not more than 0.2 m/s.

If, after the measurements being implemented, it is obvious that these indicators have exceeded the norm, it is imperative to clean the ventilation in the apartment. Also, all the necessary parameters must be registered in the household premises - bathroom, toilet, kitchen, pantry. There are necessarily exhaust ducts here that collect air under pressure and release it into the environment, but if the ventilation is polluted, the quality and result of the system's operation significantly drop and worsen the sanitary and epidemiological situation. Among other things, the ventilation passages can be chosen by various harmful insects and rodents that carry a dangerous infection.

Who checks the condition of the ventilation ducts

Apartments refer to the types of property objects that are in the personal ownership of their owners. In addition, individuals own on a general basis some more objects, including ventilation, a roof, an entrance, and so on. For all public facilities of this kind, the managing organization is responsible, with which the residents of the apartment building have entered into an appropriate agreement. In this regard, it is this service that is obliged to monitor the current state of the ventilation ducts, as well as take care of their safe operation.

The Government of the Russian Federation approved Decree No. 410, which reflects all the rules according to which the managing organization must act at the time of checking the condition of the ventilation ducts. Verification can only be done by those organizations that specialize in the relevant activities, and also have a license to conduct it. Also in this document are recorded all the requirements that must be met when cleaning the ventilation.

Functional purpose of ventilation

The air that we breathe in the apartment only seems to be clean. In fact, it absorbs all the smells coming from the kitchen, carbon monoxide from the stove. Particles of dust, villi from clothes, carpets, pet hair get into it.

Harmful microorganisms and bacteria accumulate in the air, which contribute to the development of serious diseases, moisture and steam coming from the bathroom cause the formation of fungus and captivity. All this negatively affects the microclimate of the room, contributes to the appearance of lung diseases, allergies and other ailments.

The ventilation system is designed to collect and remove air clogged with dust, toxic compounds, harmful microorganisms, fats, carbon dioxide and other substances that reduce performance and affect the general physical condition

The condition of ventilation openings, ducts and equipment must be regularly monitored, because. they tend to get dirty

According to the principle of operation, ventilation systems are divided into natural, mechanical and mixed. In mechanical and mixed varieties, air exchange is more intense, they have to be cleaned more often

Ventilation ducts and openings are most often cleaned mechanically using a hard ruff on a long handle.

Cleaned channels and ventilation holes will ensure the outflow of polluted air in the required volume and the influx of fresh air mass in its place

At enterprises with actively operating ventilation, which removes highly polluted air, they often resort to purging channels because of their length and the difficulty of eliminating traffic jams.

Mixed and mechanical varieties of ventilation systems require regular cleaning of filters and related components

If in the room, in addition to the ventilation system, an air conditioner is operating that draws air from the street, it is also necessary to clean its channels at the frequency specified by the manufacturer

Ventilation, which performs several important functions, helps to avoid negative health consequences:

• ensures the supply of clean air to the apartment,
• allows you to remove odors, dust, bacteria, carbon monoxide and other harmful components from the room;
• regulates the humidity level.

Ventilation is one of the vital engineering communications of an apartment building. The State Commission will never accept an object in which the ventilation system is missing or defective.

With insufficient air circulation and poorly functioning ventilation, mold and fungus can form on the walls of the room.

Types of ventilation

Natural ventilation provides for air circulation, which is created due to the difference in air temperature in the street and in the apartment, and atmospheric pressure. These are the cheapest ventilation systems, so almost all old houses are equipped with them. But the system is not widely popular, as it is completely dependent on weather conditions.

Artificial ventilation involves air circulation, which is created using special equipment. These systems are currently used in all apartment buildings.

Supply ventilation brings fresh air into the room, and exhaust ventilation removes polluted air using ventilated appliances, and today is the most common system. Therefore, many people have such questions as how to clean the supply and exhaust ventilation. For those who have not experienced this, it will be difficult to perform this procedure, but the following information will help you.

Sooner or later, but any air circulation system becomes clogged and does not function well, and the main signs that you need to clean the ventilation in the house are:

• air blockage;
• a large amount of condensation on the windows and dampness in the apartment, darkened corners;
• the formation of a web around the entrance to the system;
• large accumulation of dust and small debris.

Diagnosis of problems with the hood in the bathroom

Special diagnostics aimed at checking the draft will help assess the condition of the ventilation system. The event is carried out in several stages using improvised means or special devices.

It is better to check the operation of natural ventilation in the cold season. Before this, it is recommended to ensure the flow of fresh air: open the window or set the windows to the ventilation mode. In sanitary rooms, the door should be slightly opened.

The easiest way to diagnose at home is to check with fire

You need to take a lit match, lighter or candle and carefully bring the flame to the grate of the ventilation duct, which removes the exhaust air from the bathroom. The functionality of ventilation ducts is evaluated by the behavior of the flame brought to the grate:

The functionality of ventilation ducts is evaluated by the behavior of the flame brought to the grate:

• deviates towards the grating - the system is working, the thrust is normal;
• remains in the same position - there is no traction;
• deviates towards the room - there is a reverse thrust.

It is worth considering that this technique is unsafe and is highly discouraged for use by gas service specialists. If there is a leak in the house, gas accumulates in the ventilation shafts. Under such circumstances, an open flame can start a fire or explosion.

A safer way is to test with a thin sheet of paper. As in the previous case, it is brought to the vent. The paper is taken by the lower tip and held in a vertical position near the grate.

If the paper is strongly attracted to the grate and held on to it, the ventilation works well. A short sticking or a slight deviation towards the hole indicates weak traction. If nothing happens, and the sheet remains motionless, the system is faulty. Paper repulsion is a sign of reverse thrust

The outflow of air can also be felt thanks to tactile sensations. To do this, wet your hand and bring your wet palm to the outlet. The presence of air flow is determined by the cooling breath.

These diagnostic options will only give a general idea of ​​​​the performance of ventilation in the bathroom. It is possible to obtain a quantitative assessment of the efficiency and determine the compliance of the state of the system with the standards using special instruments - anemometers.

Anemometers measure the speed of air flow in a ventilation duct. Often they are used by professionals, but simple models are quite suitable for use at home.

The device is brought to the ventilation grill at a distance specified in the instructions. After a few seconds, the display shows the airflow rate (V). Having fixed the received figure, it is necessary to calculate the volume of air passed through the system according to the formula:

Q \u003d V x S x 360,

where

• S is the cross-sectional area of ​​the ventilation duct in m²;
• V is the speed of the air flow.

The result is compared with the normative parameters. The optimal value for the bathroom is 25 m³ / h.The norm for combined bathrooms should be twice as much.

We also recommend that you familiarize yourself with the rules for checking the operation of ventilation ducts in the apartment.

1 A look into the historical past

Few people know that for the first time the ancient Egyptians were able to provide the inflow and outflow of fresh air into the room. In the famous pyramid of Cheops, scientists counted more than 300 passages, channels and small tunnels through which oxygen passed. Cleaning of ventilation in those days was not carried out, since the system was organized in such a way that it practically did not clog.

The openings of the "ventilation shafts" in the King's Chamber are located on the southern and northern walls at a distance of 2.49 m and 2.48 m (eastern walls of the holes)

At the end of the 18th century, the first ventilation wells appeared in the houses, thanks to which the microclimate of the living space improved, as did the general health of the owners. However, the emergence of something new is inevitably accompanied by the emergence of related problems. Therefore, it became necessary to regularly clean the ventilation ducts.

At the end of the 18th century, the profession of a chimney sweep was one of the most honorable

Brick wells did not have any protective filters. The surface of the masonry was characterized by a pronounced roughness, which helped to retain small particles in the form of dust, cobwebs and dead insects. There was a need for a new service for that time - cleaning of ventilation ducts. Dusty and not very pleasant work was done by chimney sweeps. In fairness, it should be noted that their work was generously paid, and the specialists themselves were held in high esteem.
