Installation of ventilation of industrial facilities. Industrial ventilation systems Industrial ventilation systems
Production ventilation is a set of measures aimed at organizing and maintaining stable air exchange in industrial premises. Operating equipment and production processes are often a source of airborne particles and toxic fumes, which can adversely affect human health. In addition, the lack of fresh air reduces productivity and the ability to endure physical activity.

Solution
Ventilation of industrial facilities is essentially the supply of fresh air and the removal of exhaust air. And it includes a number of solutions.
The first stage is planning. And for this it is necessary to take into account several important conditions: the presence of harmful fumes in the premises, gas contamination and temperature conditions.
To solve the tasks, it is necessary to take into account the necessary conditions labor, as well as build on the parameters of the premises and its specifications.
Most often, in large rooms, supply and exhaust ventilation with air cooling or heating is used.
Currently, there are many ventilation systems that differ in functionality and cost. Often this is a specific solution for each individual room. It is thanks to this that we get an efficient, economical, and ideally coping with the tasks set. It should be understood that the ventilation system is a very complex mechanism that not only provides clean and fresh air in the room, and therefore high performance not only of equipment, but also of employees, as well as their well-being, and also allows you to control many parameters to create optimal climatic conditions depending on the time or part of the room. The ventilation system can be controlled mechanically or electronically, but mixed types are also possible.
The task of industrial ventilation
The main task of industrial ventilation is to ensure the constant presence of clean air in the premises (without impurities, odor and harmful components). This is ensured in 2 ways: by removing polluted air masses from the workshops and by providing an influx of fresh air. The second task is to maintain a certain microclimate. This includes temperature and humidity requirements. These requirements are especially relevant for industries accompanied by a large release of heat, moisture and harmful fumes.
A professionally designed ventilation system contributes to the following benefits:
- staff get sick less
- labor productivity increases
- a favorable microclimate is maintained
- moisture does not accumulate on the equipment, the metal does not oxidize or corrode
- compliance with the requirements for production processes.
Exhaust aeration in production
Air ducts are mainly used for ventilation of local spaces inaccessible to infiltration flows. The movement and distribution of air occurs without external coercion, only under the influence of temperature differences and atmospheric pressure outside and inside the room. To increase the efficiency of aeration, deflectors are installed at the outlet, special expansion nozzles that draw the exhaust air out of the room. This is also facilitated by window transoms and ajar skylights.
In summer, the role of supply air channels is performed by open gates, openings in the outer walls and doors. In the cold season, in warehouses up to 6 meters high, only openings are opened at a height of at least 3 meters from the zero mark. With a height of more than 6 meters, the bottom of the ventilation openings is designed at a distance of 4 meters from the floor level. All openings are equipped with water-repellent visors, which, moreover, deflect the supply air jets upwards.
Supply and exhaust aeration
Extraction of polluted air occurs due to transoms and ventilation shafts. Transoms act as a kind of thermal damper, the opening and closing of which regulates the air pressure in the ventilation streams. As an additional pressure regulator, special holes are designed, equipped with louvered doors:
- slightly above floor level - stimulating air flow,
- just below the ceiling level - optimizing its outflow.
The volume of circulating air is proportional to the area of open transoms, openings and vents.
Note
- If the concentration of harmful substances in the outdoor air exceeds the maximum allowable limits by 30%, natural ventilation is not used.
- The elements of the upper hood are installed approximately 10-15 degrees below the ridge on the roof. This reduces the risk of their destruction.
Design and installation
To ensure the highest quality ventilation, it is necessary to carry out its design and installation already at the construction stage. This is the only way to take into account all safety measures, to properly design exhaust zones.
But it also happens that it is necessary to install a ventilation system in an already built building. In this case, you should take into account all the conditions in which the system will be operated, as well as the purpose of the room itself. The choice of equipment always depends on the explosion and fire hazard of the room.
As is known, general exchange and local ventilation is used for industrial premises. The first is responsible for air exchange and air purification of the entire room. But with the help of local suctions, it is possible to solve only local problems at the place of formation of those very harmful substances. But it is not possible to keep and neutralize such air flows completely, preventing their spread throughout the room. Here additional elements are needed, such as umbrellas.
The choice of equipment for the installation of ventilation of industrial premises is influenced by the type of production and the amount of harmful substances emitted, the parameters of the premises itself, and the design temperature for the cold and warm seasons.
Summing up, I would like to say that such a difficult task as the calculation, design and subsequent installation of ventilation should be performed by qualified specialists who have a wealth of knowledge and years of experience behind them.
Classification of industrial ventilation by type of action
There are different types industrial ventilation. They are classified according to the following parameters:
- the method of organizing the inflow and outflow of air masses (natural, forced);
- by functionality (supply, exhaust, supply and exhaust);
- method of organization (local, general exchange);
- design features (channelless, channel).
The simplest and most cost-effective is natural ventilation. It is based on the laws of physics, when the warmer layers of air, rising up, displace the cold ones. The main disadvantage of such systems is the dependence of the season, weather conditions and a limited scope (suitable for a limited range of industries). To organize natural ventilation in production shops, 3 levels of adjustable openings (windows) are arranged. The first 2 are arranged at a height of 1-4 m from the floor, the 3rd level is under a stream or in a light-aeration lamp. Fresh air enters through the lower openings, and dirty air is forced out through the upper ones. The intensity of air exchange is regulated by opening/closing the vents. Natural ventilation can only be used for one-story buildings.
Forced ventilation- a more efficient system, including a set of equipment and engineering networks. However, you have to pay for efficiency, as it is associated with the purchase of expensive equipment and the consumption of a large number electricity.
Only supply or only exhaust ventilation is used extremely rarely (mainly in industries where air pollution is low). Much more common supply and exhaust systems providing more uniform air exchange.
General ventilation organized in large industries. Depending on production processes and air composition, it can be used in combination with other systems. local ventilation, unlike the general exchange, monitors the purity of the air in certain areas - for example, above the welding or painting area. This type is selected if the general exchange does not cope with ventilation in all rooms.
What gives a combination of local exhaust and supply general exchange systems? Taking in polluted air, the exhaust system does not allow it to spread throughout the room, and the supply system provides fresh air inflow (it can be equipped with filters and a heating system).
duct ventilation involves the organization of boxes or pipes of large cross-section, designed to transport air. Channelless systems - a set of fans and air conditioners built into the openings of walls or ceilings.
Design of ventilation of production shops
Design industrial ventilation systems has its own specifics. There is no universal equipment that can meet the needs of all types of industries. When designing, a lot of data is taken into account. The algorithm for solving the problem is as follows:
- Calculation of the required air exchange.
- Selection of equipment that supports the calculated parameters.
- Calculation of air ducts.
At the first stage of design, a technical task(TK). It is compiled by the customer and includes requirements for air parameters, features technological processes, tasks of the system.
- architectural plan of the object with reference to the area;
- construction drawings of the building, including a general view and sections;
- the number of employees in one shift;
- facility operation mode (one-shift, two-shift, round-the-clock);
- features of technological processes;
- potentially dangerous zones with reference to the plan;
- required air parameters (temperature, humidity) in winter and summer.
The calculation of the required air exchange is carried out in the following areas:
- supply of fresh air according to sanitary standards (according to the norms per person 20-60 m³ / h);
- heat assimilation;
- moisture assimilation;
- dilution of air to the maximum permissible concentrations of harmful substances.
The largest air exchange obtained as a result of the calculations described above is taken as the basis.
Using the emergency ventilation system
According to SNiP ("Ventilation of special and industrial buildings") in hazardous industries, it is necessary to provide emergency ventilation system. An emergency situation may arise in the event of an emergency release of explosive or toxic gases, a fire. She represents completely self-installation exhaust type and is calculated in such a way that when working with a conventional system, 8 air changes are provided in 1 hour.
Ventilation systems management
Automation control of ventilation systems allows you to optimize the process and reduce operating costs. This approach allows minimizing human participation in management and reducing the risk of the "human factor". Automatic control involves the installation of sensors that record the temperature / humidity of the air, the concentration of harmful substances, the degree of smoke or gas contamination. All sensors are connected to the control unit, which, thanks to the specified settings, turns the equipment on or off. Thus, automation helps to comply with the requirements of sanitary standards, quickly respond to emergencies and save significant money.
Ventilation systems are one of the main consumers of electrical and thermal energy, so the introduction of energy saving measures allows to reduce the cost of products. The most effective measures include the use air recovery systems, air recirculation and electric / motors with no "dead zones".
The principle of recuperation is based on the transfer of heat from the displaced air to the heat exchanger, which reduces heating costs. The most widespread recuperators are plate and rotary type, as well as installations with an intermediate coolant. The efficiency of this equipment reaches 60-85%.
The principle of recirculation is based on the reuse of air after it has been filtered. At the same time, part of the air from the outside is mixed in with it. This technology is used during the cold season in order to save heating costs. It is not used in hazardous industries, in the air of which there may be harmful substances 1,2 and 3 hazard classes, pathogens, unpleasant odors and where there is a high probability of occurrence emergencies associated with a sharp increase in the concentration of flammable and explosive substances in the air.
Given that most electric motors have a so-called "dead zone", their proper selection allows you to save energy. As a rule, "dead zones" appear during start-up, when the fan is running in idle mode, or when the mains resistance is much less than what is required for its correct operation. In order to avoid this phenomenon, motors with the possibility of smooth speed control and with no starting currents are used, which saves energy at start-up and during operation.

During operation, indoor air changes its parameters - temperature, humidity and composition under the influence of a variety of factors: changes in outdoor air parameters, heat release, moisture and carbon dioxide from people, dust and other harmful substances from operating equipment, machines, installations. In this regard, it is necessary to carry out air exchange, i.e. remove polluted indoor air and replace it with purified fresh (outdoor) air. The task of ventilation is to provide air exchange in industrial premises to maintain the calculated air parameters in them.
Air parameters can be:
- comfortable and they are provided by ventilation systems of residential and administrative facilities;
- admissible, achieved due to the work of ventilation of industrial buildings.
Other tasks are often set before the ventilation systems of industrial premises: the removal of smoke (in case of fire), dust and harmful substances (during the operation of machines, assemblies and equipment). Ventilation of industrial premises is a set of devices and measures that provide calculated air exchange. Depending on the processed air flow, a distinction is made between domestic (up to 10,000 m³/h) and industrial ventilation (over 10,000 m³/h). Ventilation of industrial buildings is a mandatory measure in production workshops, hangars and other premises where technological equipment, people or mechanisms work.
Ventilation of industrial buildings
Industrial ventilation equipment, due to large amounts of moving air, is distinguished by its weight and size characteristics, energy consumption and increased requirements for its reliability and safety. The work of any, including industrial ventilation, is provided by several engineering systems called ventilation systems. They consist of devices of various designs, each of which performs its own function:
- air circulation - fans;
- air purification - filters different class cleaning;
- air flow control - air valves and dampers;
- air heating and cooling - air heaters and air coolers;
- air distribution throughout the room - diffusers, anemostats and grilles;
- air supply and removal - air ducts;
- vibration reduction - flexible connectors and vibration isolators;
- noise reduction - silencers.
Ventilation of industrial premises
Measures include proper management of industrial ventilation, compliance with standard air velocities in air ducts to reduce the level of aerodynamic noise, compliance with manufacturing technology, installation, and sealing of air ducts to reduce leaks to a minimum. Currently, for the ventilation of industrial premises and the simultaneous organization of supply and exhaust, industrial ventilation units are used, which allow performing most of these functions with the help of one unit - a supply and exhaust unit. The peculiarity of these units is that their design combines supply and exhaust units, which in turn allows you to get a better price, apply various systems recovery and make the process of ventilation of industrial premises more efficient.
Peculiarities
According to their purpose, ventilation units are divided into:
- supply;
- exhaust;
- supply and exhaust;
- recuperative (supply and exhaust with a recuperator).
Industrial ventilation is installed in manufacturing plants, retail and warehouse premises, sports and concert halls and other large buildings. It ensures the maintenance of optimal climatic conditions for people, removes harmful chemical and explosive compounds and industrial dust from the premises. It can be general or local, exhaust, supply or supply / exhaust. When developing the project, the purpose of the facilities, the composition of the air mixture, the volume of the premises and the requirements of regulations and industry regulations for air quality are taken into account.
Design and installation works are carried out taking into account the requirements of SNiP 3.01.01-85 and SNiP 3.05.01-85, only licensed companies with a full staff of highly qualified employees of various specialties are allowed to perform. The installation of an industrial ventilation system consists of several separate stages, each of which performs certain actions and controls the quality.

The work is carried out on the basis of the PPR, the document provides details on the nomenclature and number of elements and special units, technical conditions for the installation, circuit diagrams engineering solutions of the main units. Industrial ventilation systems must be installed during construction work to avoid alteration of architectural elements and structures. At large facilities, installation is carried out by the zone method as soon as the scope of work is ready. In this case, the following rules must be observed:
- To provide heat for buildings under construction, supply chambers should be installed as a matter of priority. This will make it possible to maintain the temperature in the premises at favorable values and guarantee the continuation of work in the winter period.
- Passages and fastening of air ducts through the roof are carried out before its final covering with roofing materials. The final coating of the roof is done only after the complete completion of the installation of ventilation systems and quality control. Further modification of the air duct layout is strictly prohibited.
- Air ducts passing through load-bearing walls or lintels are recommended to be made before they are erected. This eliminates the need for subsequent chiselling of the walls to pass pipes. If several subcontractors work at the facility, then an agreement between them on the work plan is required. Based on the agreements, a general schedule is drawn up, the document is signed by all parties.
Checking the tightness of the joints is carried out before the completion of construction work to seal the holes. Due to this sequence, work to eliminate the identified problem areas is much easier. After verification, an act is drawn up for hidden work. Installation of embedded parts is carried out simultaneously with the installation of design building structures, it is forbidden to violate the installation technology. If technical errors were found during the installation of industrial ventilation, it is recommended to call the designers and coordinate further actions with them.
Installation of air ducts
Mounted in the manner provided in the standard technological maps. A specific method takes into account the horizontal or vertical position, spatial placement relative to architectural structures: external or internal, between floor trusses, near columns or walls. This takes into account the total usable area and number of storeys of the building.
Installation of vertical ventilation
Installation of horizontal ventilation
For shaped parts of the ventilation system with complex geometry, flexible air ducts are used, made of non-woven polymer materials or aluminum foil. The use of flexible ducts in straight sections is prohibited, their installation causes a noticeable loss in air flow velocity. As a result, an increase in the cost of maintaining the calculated indicators of the frequency of air exchange in the premises, maintenance of the ventilation system is more expensive than the prescribed standards, and the cost of production increases. In order to increase bandwidth flexible sections during installation, a minimum coefficient of their compression is provided.

Fittings for rectangular ventilation
Technological stages of work production
Industrial installation of air ducts is carried out in large blocks in the following sequence:
- Marking specific places for fixing air ducts, taking into account their diameter and weight. At the same time, a set of measures is taken to reduce the number of bends, ventilation systems should be as straightforward as possible.
- Installation of fastening devices, taking into account the dimensions of the pipes and the material of manufacture of the bearing surfaces. If necessary, the places of fixation of lifting mechanisms for moving heavy structural units are agreed with the builders.
- Delivery of parts, fixtures and assemblies to the place of installation. Their completeness and safety are rechecked. If mechanical damage is detected, defects are eliminated before installation begins.
- Assembly of individual elements into enlarged blocks. Using the block method for industrial ventilation allows you to reduce time and improve the quality of work.
- Installation of blocks in the places provided for by the design documentation, checking the quality of fixation.

The linear parameters of the blocks depend on the cross-sectional parameters of the air ducts and the selected type of their connection, the specific conditions for the installation of the air ducts and the technical characteristics of the lifting mechanisms used. The entire installation process is carried out by operational quality control, taking into account the provisions of the map developed by the designers. If possible, industrial ventilation is equipped with a minimum number of bends and bends.
Fan mounting
The calculation of fans for industrial ventilation is carried out on the basis of the customer's specifications and taking into account current standards and regulations. Installation methods and the procedure for performing preparatory operations depend on the type of fan (roof, axial, fan), mounting location and dimensions. Installation of an air duct with a fan is carried out in the following sequence:
- Checking the readiness of premises for ventilation chambers, delivery of units and its constituent parts to the installation site. Assembling the unit and checking its performance.
- Lifting the fan to the place of installation, fastening it to the supporting structures, re-checking the performance. Installation of air ducts to the inlet and outlet technological openings of the fan.

Quality Assurance Activities
The efficiency of industrial ventilation is ensured by quality control at each stage of work in accordance with the requirements of SNiPa 30101-85 and industry standards of the KS UK SMP. The list of activities includes the following steps:
- Control of working documentation for the ventilation system. Compliance of the technical indicators of the system with the production task, the features of operation and the characteristics of the building is checked.
- Checking the condition of equipment, pipelines for air ducts, control and management units. The actual characteristics are compared with those indicated in the technical passport.
- Control of the stages of assembly and installation. The assembly and installation of ventilation systems must comply with design documents and the requirements of building regulations.
Operational control of the installation of industrial ventilation is carried out as each stage of work is completed, ensures timely detection of deviations from the recommended technology and their immediate elimination. The results are recorded in a special journal and certified by the signatures of the responsible persons. Operational control is carried out constantly at all stages of work.
Acceptance control of the ventilation system provides for checking the compliance of the work performed with the working design and the WEP. The system is started and operation in various modes is checked. At the same time, special devices measure the speed of air movement in various areas, the functionality of the installed equipment and units.

Industrial ventilation differs from residential ventilation not only in scale, but also in the equipment used, requirements and a number of other parameters.
Ventilation of industrial premises must be able to cope with a number of challenging tasks
Ventilation systems in industrial enterprises must cope with a number of complex tasks: with the extraction of a large volume of exhaust air from the premises, therefore, their design and installation must be approached with special attention.
Types of industrial ventilation
Like domestic, industrial ventilation can be of two main types.
- Natural - exhaust ventilation, in which the air circulation in the facility is carried out due to the natural flow of air masses through the ventilation ducts. The operation of such a project is based on the difference in temperatures and pressures inside and outside the premises. The design of natural type industrial ventilation should be carried out taking into account the amount of heat emanating from the production equipment.
- Forced - ventilation system of premises, in which specialized equipment is used to circulate air masses. Such a scheme is good in that its performance and efficiency are completely independent of weather conditions, and air supply and exhaust are provided by fans and other equipment.
Each of these industrial ventilation systems has its own installation and operation features, as well as advantages and disadvantages.
For example, installation of industrial ventilation of natural type will allow you to significantly save on ventilation of premises, but mechanical forced ventilation will cope with the removal and inflow of air, regardless of the air temperature outside and other factors.
Features and principle of operation of industrial ventilation of natural type
If for your company you have chosen the installation of industrial ventilation, which operates solely due to the difference in temperature and pressure in the room and outside, then in this case industrial equipment during operation should not emit harmful substances into the environment. Otherwise, you can not do without supply and exhaust ventilation with air filtration.
In order for the exhaust air to leave the production premises in a natural way, it is necessary to calculate and install special ventilation openings, which should be located at different heights.
The principle of operation of natural air exchange in the room is as follows:
- heated air rises and leaves the premises through holes made in advance;
- heavier clean cold air descends through the same holes down;
- the air flows are mixed, the exhaust air goes out, the clean one gets inside.
Ventilation of industrial buildings in this way is rarely used, since its efficiency is not enough to provide a large industrial area with fresh air. Even the most accurate calculation will not help where the equipment works with the release of harmful substances into the air.
Benefits of forced industrial ventilation
Industrial ventilation systems that use specialized ventilation equipment to provide efficient air exchange are much more efficient and boast their own benefits.
- Large footprint - industrial air handling units use special powerful fans that provide intense airflow.
- Efficiency - the operation of an industrial ventilation system does not depend on any external conditions.
- Additional features - this includes the ability of supply and exhaust systems to filter the air at the facilities, humidify it or dry it.
- Targeted supply of air flows - with proper design and installation, it is possible to direct fresh air directly to the workplaces.
- Increasing the safety of work - forced-type ventilation of industrial facilities can capture and remove harmful substances, dangerous gases from the air in the industrial premises, and purify the air masses.
- The possibility of carrying out installation work in buildings after their construction is completed. This favorably distinguishes forced ventilation from natural ventilation, the design of which must be dealt with at the design stage of the entire building.
The disadvantages of a forced ventilation system include the high cost of equipment that the system needs to fulfill its purpose.
The main disadvantage of forced ventilation is the high price.
In addition, equipment for the circulation of air masses produces a lot of noise during operation, therefore, when installing such installations at the enterprise, it will also be necessary to calculate the sound insulation.
Types of industrial forced ventilation systems
The purpose and classification of supply and exhaust ventilation can be different. There are five types of forced ventilation.
- General exchange - such ventilation provides air exchange throughout the facility. Most often, such a hood is installed in rooms in which work is carried out with poisonous and harmful environment substances, as well as where there are no fixed jobs.
- Local ventilation of industrial enterprises - such ventilation is used where it is necessary to ensure effective air extraction in a particular area. For example, local equipment is used for its intended purpose, if it is necessary to remove the exhaust air from the source of the emission of harmful substances.
- Mixed type - by installing such exhaust equipment, you guarantee the ability not only to carry out general air exchange, but also to carry out ventilation in the workplace.
Regardless of the type, designing the ventilation of an industrial building involves complex calculations. In ventilation systems, different principles of air supply are distinguished:
- supply air - the exhaust scheme implies the presence of a blower fan, and the outlet of the exhaust air occurs due to the fact that the pressure in the room increases;
- exhaust - when such a system is installed in a room, the fan works for the outflow of air masses, but their entry from the outside occurs due to rarefied pressure;
- supply and exhaust - such schemes are the most effective, since in them both the air inflow into the building and the outflow are carried out by specialized equipment;
- recirculation - the calculation of such a system is carried out in such a way that the exhaust air is cleaned with the help of special filters, and then returned to the room again, representing a closed supply and exhaust circuit.
When installing the desired system, it is necessary to take into account the working conditions at the facility, as well as the needs of production.
Industrial ventilation equipment
Installation of industrial ventilation systems involves the use of specialized equipment. During calculations, some of its characteristics may change, but the main components remain unchanged.
- Ventilation ducts are special pipes, the cross section and size of which depends on the amount of air that needs to be driven out per unit of time. It is on the correct design of the channels that the efficiency of the entire system depends, it is through them that air is transported through the facility. Channels can be made of plastic, aluminum, metal and other materials.
- Fans are the main component of any air circulation system, provide required power, and also set the direction of air flow.
- Fittings - like pipes, can be made of plastic, serve to connect channels, create their turns and forks.
- Filters - an industrial filter can trap large and small impurities that are inevitably found in the air of any industrial facilities. To calculate the type of filter required, it is necessary to know how dirty the air in the facility is.
- Recuperators - the difference between an industrial ventilation recuperator and a domestic one is that it is able to heat a larger amount of air per unit of time.
- Air conditioning systems - such systems must be equipped with ventilation if you want the air in the enterprise to be not only clean, but also fresh.
Recuperator - equipment for the ventilation system, necessary for heating the air
Usually, additional components can be used with basic ventilation equipment to increase the efficiency of the entire system.
Design features of industrial ventilation
Whatever the ventilation duct and whatever classification of supply or exhaust equipment you use, when installing an air circulation system in an industrial enterprise, it is always necessary to take into account certain moments and options.
Before proceeding with the calculation of ventilation, it is necessary to determine the basic conditions of the room, that is, its area, the type of equipment used, the configuration of the space, and much more.
It is worth considering the climatic features of the area in which the manufacturing enterprise is located. It is always necessary to take into account the intended purpose of the premises: if this is a plastics production workshop, then the power of the exhaust equipment should be sufficiently high.
The calculation of ventilation should include the following data:
- section of the incoming and outgoing air channels;
- the area of the ventilation openings;
- air exchange rate;
- estimated capacity of the equipment;
- the amount of materials needed to build the system.
Calculation, design and installation of ventilation systems for industrial premises is a very complex and responsible process, which must be approached very carefully.
If you do not have the skills and tools necessary for this, then it is better to entrust this work qualified professionals who will cope with it much better, and the system itself will last as long as possible and will effectively cope with the tasks.
