Ventilation of industrial premises. Industrial ventilation device Design and installation of industrial ventilation
The NIMAL company is engaged in the design and sale of equipment for the organization of industrial ventilation systems at facilities in Moscow. We work on the terms of an official dealer famous brands, we have our own production facilities and a staff of highly qualified specialists.
Features and types of systems
Ventilation complexes at industrial enterprises are developed to solve challenging tasks. They provide an extract of the exhaust air in a large volume.
Distinguish between natural and forced ventilation. With natural air circulation through the ventilation ducts, the system works due to the difference in temperature and pressure inside and outside the premises. Projects according to this scheme are developed taking into account the thermal load from machine tools and equipment.
Forced ventilation means that special devices are used to circulate air. Efficiency does not depend on the weather, the exhaust and air supply are provided by fans.
General exchange industrial ventilation with forced circulation is bought to organize air exchange throughout the facility. It is suitable for rooms where they work with harmful substances. When it is necessary to remove the release of harmful substances at a certain place, local ventilation is used. Mixed-type installations perform air exchange, ventilation of workplaces.
According to the principle of air supply, the systems are divided into:
- supply air - a blower fan is used for exhaust, the exhaust air comes out due to an increase in pressure;
- exhaust - the fan provides an outflow of air, the influx of fresh air occurs due to rarefied pressure;
- supply and exhaust - the most efficient designs, inflow and outflow is provided by specialized equipment;
- recirculation - the exhaust air is cleaned by filters and returned back, the system operates in a closed circuit.
NIMAL specialists design and calculate ventilation taking into account the operating conditions of the facility, its area, configuration and type of equipment used.

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 is used, 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, use various recuperation systems 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).

The rapid pace of development of output ready-made solutions for air ventilation today - the result of increased consumption of products for housing and office construction, manufacturing enterprises. In the last 10 years, this segment of the industry has been developing - its share in the total market volume has increased from 5 to 8%.
Russian factories, taking advantage of the current economic situation, seek to integrate into the market by establishing their own production capacities. The growth in the value of the dollar and the euro, which caused a rise in the cost of imported ventilation and air conditioning equipment by 40% - 45%, played into the hands of Russian manufacturers, whose products, made from Russian raw materials and components, remained in the same price category. Western brands are losing competitive advantages both in Russia and abroad. Russian market leaders:
GK "Special Systems and Technologies" is a major player in the industry in terms of quality and related services, 40% of the Russian market for air conditioning systems. Having created a sales network in Russia and neighboring countries, they export products to 42 countries of the world, including Europe and America. A separate range of solutions was developed for the Chinese subway. Today, the Group of Companies is considering schemes for entering the Chinese market, which is fundamentally different from the markets of Russia and Europe.
NPO "Teplomash", which exports products that are superior in design and technical parameters to products of local manufacturers, to Canada, the USA, European countries, CIS.
In the catalog of the online exhibition, you can directly contact Russian manufacturers of ventilation and air conditioning systems, become a product dealer or buy ventilation products in bulk at an affordable price. The factories offer the production of ventilation systems, custom-made household air equipment and export deliveries with the appropriate certificates.
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 cope with a number of complex 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 enterprise 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 release into the environment harmful substances. 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 work safety - ventilation industrial facilities forced type 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 - 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 inflow of air 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 from 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.
Modern ventilation systems and accessories for them - this is our profile, and we can offer our customers almost the entire line of moving and moving devices and mechanisms produced in the world today (ventilo in Latin - winnow, wave). They are reliable, convenient and beautiful, allowing you to fit the fans bought from us into the style of any room.
You only need to know which fan required in terms of the tasks that it will solve and the volume of the room where it is planned to be used. And then choose the equipment that suits you best from an extensive list of items.
For simple mixing of air within the same room, so that it does not stagnate, creating the effect of a breath of wind, we have a variety of bladed and bladeless fans desktop, floor, wall and ceiling mounting. All of them have an attractive design, powerful engines that operate as quietly as possible, several speeds of operation and are very inexpensive.
However, real ventilation with ventilation, that is, the injection of fresh air into the room and the removal of polluted air by such devices is not carried out. For this we need exactly ventilation systems different power. We have them in all three types of their purpose: supply, exhaust, general exchange with a full cycle of all operations: extracting old air, ejecting it and forcing fresh air.
We offer turnkey ventilation systems
We will tell and show you which ventilation systems can offer you "Vent-style" in terms of their functional features.
Forced ventilation designed to provide fresh air into the room. Previously, natural ventilation was mainly used - due to the difference in air temperatures inside and outside, air exchange occurred. But such a ventilation system is too dependent on climatic conditions, and artificial ventilation, carried out with the help of a fan, heater, air ducts, will always work.
Exhaust ventilation removes stale air from the room, allowing clean air to naturally penetrate into it. It is advisable to install exhaust ventilation in kitchens, hallways, bathrooms, that is, not in residential premises, but in domestic premises. When designing industrial premises, exhaust ventilation can be equipped with designing industrial premises, then exhaust ventilation can be equipped with an additional filtration filtration system.
General ventilation today it is used most often, because it provides for the intake of air, its removal and the influx of fresh air masses.
General exchange ventilation it is completed, as a rule, with a set of filters that do not allow polluting the atmosphere and clean the air supplied to the premises from dust particles, as well as devices for its additional heating or cooling.
Here you can choose any ventilation system"turnkey" with its complete set of any elements: filters and air ducts for round and rectangular ducts, transformer and seven-story speed controllers, valves, additional silencers.
