Basic ventilation functions
It is important to have an idea about the purpose of the ventilation system, as well as to know what parameters and characteristics it possesses.
Indoor ventilation performs a number of functions:
- Evacuation of waste, polluted air and the flow of new from the street. In some situations, purification, ionization, cooling and heating of the air mass occurs.
- Various impurities and odors are removed from the room. This has a positive effect on the well-being and efficiency of people in the room.
The air exchange system is able to fully cope with its functions when it is perfectly clean. For these purposes, it needs regular cleaning. It will increase the efficiency of technology and eliminate the possible appearance of allergic reactions in people due to the accumulation of dust and various impurities.
In the air there are small particles of dirt and debris that fall into the ventilation channel. In the absence of regular cleaning, they form deposits that reduce the internal section of the duct
Features of the ventilation system
Not only dust, but also microbes, allergens, mold organisms, fungal spores, leave through the ventilation channels. Over time, they settle on the inside of the ventilation, from where they spread around the room. In addition, the dusty network is a conductor of fire and a source of suffocating burning in case of fire.
Why do you need to clean the ventilation channels
Timely cleaning of the canals helps purify the air, regulates the humidity index and prevents the development of fungus and black mold. And also it allows you to create ideal microclimatic conditions in the room and deal with the problems of the engineering system.
In addition, cleaning helps to ensure compliance with fire safety regulations. If dust and fat deposits are observed in the ventilation ducts, if a small spark occurs in the duct, a fire may occur. And the spread of fire will be fast.
It is important for a person to secure comfortable living conditions. Purification of ventilation ensures the creation of a perfectly functioning ventilation system
Cleaning the air ducts allows you to perform sanitary standards, from which the well-being and health of each person depends. Timely maintenance of ventilation channels will provide a favorable atmosphere and a comfortable indoor microclimate.
This is important both in residential areas and in the workplace, where people spend a lot of time.
Frequency of service of ventilation systems
Ventilation is a necessary element of residential, industrial, commercial and warehouse space. If you do not take into account the technical features, the ventilation system is conditionally divided into 2 types: natural and forced. Each of them needs constant cleaning.
It is carried out as the ventilation channels are contaminated or periodically as a preventive measure. In the second case, the procedures do not depend on the degree of contamination.
This option is more optimal, as it guarantees efficient and long-lasting ventilation. It will also ensure a comfortable atmosphere in the room, while the ventilation system will fully perform its functions.
Constant maintenance of the ventilation system of the room in normal working condition allows creating a microclimate favorable for work and rest.
If the maintenance of all elements of the ventilation system will be performed regularly, the room will be perfectly clean air. Favorable microclimate has a positive effect on the health of people who live or work indoors.
Main signs of contamination
Cleaning the ventilation system in the apartment should be carried out regularly. Otherwise, dirt, dust and various deposits begin to circulate in the room with air currents, causing harm to human health.
The need for cleaning is indicated by a number of signs:
- dust and cobwebs are constantly gathering around the grate;
- it is stuffy in the room, although this has not been observed before;
- the next day after cleaning the apartment dust accumulates on the floor.
To test the system in a small room, you can use the visual method, smoke or open flame. In case of inadequate cleaning, it should be carried out.
Special tools are used to assess the condition of large area ventilation systems.
Periodically it is necessary to carry out a performance check of the ventilation system. This will avoid fire situations.
Technologies and methods of service
The ventilation system provides air circulation from the room and back. Universal equipment eliminates dirt and dust, allows you to keep the room clean. Air purification should be carried out both at the production using industrial installations and in residential buildings.
The system for air purification can solve different problems. Some of them are designed to get rid of part of the dust, others are designed to combat fats and fumes. On the inner walls of the equipment there are different deposits, depending on which use the best option for service work.
Mechanical maintenance method
The cleaning procedure involves the use of special equipment - a vacuum cleaner, brush machine or a robot equipped with a video camera and special brushes. The mechanical method is characterized by high speed and efficiency, however, it is not suitable for removing fat deposits.
Its main advantage is safety for people working or living in the building. Effectively removing pollution from the duct walls, the equipment does not damage the elements of the ventilation system.
Chemical cleaning method
Using mechanical means, it is not always possible to get rid of strong pollution. In public kitchens often have to apply dry cleaning of air ducts. This is necessary if there is a significant load on the ventilation system or the owner of the room does not comply with equipment cleaning standards.
If the ventilation system is very dirty, a chemical cleaning method is used. This method will allow to get the desired result and return the ventilation channels to the normal state.
Cleaning is carried out by spraying special chemicals through the air duct.
The chemical method is the fastest and most effective. It requires prior preparation, since the cleaning products used are toxic.
Other options for the procedure
The combined cleaning method is also called wet. It involves the use of chemical and mechanical cleaning methods, which are carried out in turn. The advantages of the method are high efficiency.
Among the disadvantages of this method of service work:
- quite high cost;
- its implementation takes a long time.
Another expensive cleaning option is cryogenic blasting. It involves the use of dry ice or soda.
The substance used by compressed air at high speed enters the ventilation, where it crashes into contaminated walls. As a result, a microexplosion occurs, effectively destroying plaque on the inner surface of the ventilation channel.
The lack of blasting - the procedure requires sealing the system and a lot of time. But this method allows you to effectively cope with deposits on the walls.
There are various methods of cleaning the ventilation system. They are selected depending on the factors: the purpose of the hood, the requirements and technical capabilities of the client
In practice, mechanical or combined cleaning is often used. These techniques allow you to remove deposits of greasy deposits and dust from the inner walls of the ventilation system. The remaining methods are relevant in the presence of complex contaminants that simple tools cannot cope with.
Types of equipment for maintenance of ventilation system
Dust, dirt, fatty and fungal accumulations accumulated inside the ventilation system are not always easily separated from the walls. Usually this requires the skills of professionals and special equipment.
Professionals use special equipment to remove deposits from the duct. It is intended for maintenance and cleaning of the ventilation system in various premises.
