Ventilation of industrial premises. Installation of ventilation of industrial facilities Benefits of forced industrial ventilation

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 contaminated 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.

We will help you pick up and deliver to your destination any fans And ventilation systems in a set for residential, public and industrial premises, including volumetric exhaust units installed on the roofs of buildings.

In addition, we have a wide range of high-temperature fans that cool electronic devices, installations and equipment used in a wide range of applications - from home computers to factory assembly shops. There are also special channel high-temperature fans for removal of air from fireplaces and other constructions.

Please note that all the motors of our fans for domestic and industrial purposes are mounted in soundproof housings and are equipped with overheating protection with an automatic restart function.
You can be sure that what we offer ventilation systems have certificates of conformity to the quality established by state standards and warranty periods of operation.

Features and types of systems

Ventilation complexes at industrial enterprises are developed to solve complex problems. 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.

We offer to buy industrial ventilation equipment for organizing efficient air exchange at enterprises, we provide a range of services from system design to installation and commissioning at competitive prices in Moscow.

Hardware Benefits

• Functionality - systems filter, humidify and dry the air. With proper design, you can organize the air supply to the workplace.
• Creating a safe environment - the equipment removes dangerous gases, substances and purifies the air.
• Ease of installation - devices can be installed in already built buildings.

Various types of ventilation equipment are on sale for completing any production facilities. We will advise you on the optimal choice.

To create and maintain an optimal environment for efficient life, it is necessary to install ventilation equipment. Modern system ventilation in summer will be provided by filtered outside air, and in winter - also heated. In addition, good ventilation will maintain a constant temperature and humidity, control the level of concentration of substances harmful to health.

Types of ventilation

There are several types of ventilation systems that can be combined into groups:

• According to the method of air movement (natural, mechanical)
• By the method of organizing air exchange (local, general)
• According to the principle of operation (exhaust, supply)
• By design (monoblock, type-setting)
• By the presence of air ducts (ducted, non-ducted)

Whatever system you choose, it is essential to maintain a balance - simultaneous intake of outside air and exhaust of exhaust air. If the inflow is insufficient, then the oxygen content will decrease, and the humidity and dust content will increase. If there is not enough exhaust, then polluted air, unpleasant odors, moisture and harmful substances will remain in the room.

Natural

Natural ventilation is simple, does not require energy consumption and sophisticated equipment. But its effectiveness depends on temperature, wind speed, etc.

Mechanical

Mechanical ventilation moves air over long distances. Basic equipment: fans, electric motors, air heaters, automation, dust collectors.

Supply systems

Supply systems are used in apartments and small rooms. They supply air after preliminary preparation, including cleaning, cooling and heating. They can be completed in a single body or consist of various elements:

• Air intake grille
• Air valve
• filters
• heater or air heater
• Silencer
• fan
• air ducts
• Air distributors
• Adjustment and automation systems

Exhaust systems

Exhaust systems remove polluted air from a room. They may consist of a single exhaust fan, but when cleaning several rooms, an intake duct network is necessary. Supply and exhaust combinations allow you to simultaneously supply and remove air. They are developed on the basis of ventilation units or consist of different elements.

Local and public

The fight against harmful substances in indoor air is carried out with the help of local or general ventilation.

General exchange struggles with harmful substances that are contained in the air of the entire room. When installing this type of ventilation, the volume of exhaust air is calculated so that the same amount of air is extracted from the room as it is supplied. But if the air supply is not equal to the exhaust, the missing air volume is pumped from the rooms nearby or through the openings of the fences.

Local ventilation removes harmful substances from the premises in the place where they are formed.

The combined system, which includes general exchange and local exhaust systems, most effectively solves the problem of ventilation.

Channel and channelless

Channel and ductless ventilation systems are either a duct system with an extensive network of air ducts for moving air, or a system with no channels (air ducts), which is used when installing a fan in a ceiling or wall, in the presence of natural ventilation.

Ventilation of industrial premises is one of the main components, which is included in the set of measures to create favorable conditions for the indoor air environment for humans. The ventilation system must not only meet all sanitary standards, but also fully comply with the construction requirements of the building. It must also support the meteorological parameters of different rooms - this must be taken into account when installing industrial ventilation. Proper ventilation is the main condition for creating a comfortable atmosphere in the room.

The requirements that apply to different ventilation systems are also different. For example, in a country house and in a city apartment they will be completely different. In an apartment, the main factor is high-quality outdoor air purification, while for a country house the noise level is more important. Therefore, cottage owners choose ventilation systems that produce as little noise as possible during operation. Air outside the city is much cleaner than city air, so the quality of filters in the city is more stringent. Therefore, it is better to deal with the design of the ventilation system at the construction stage.

Each ventilation system must take into account the inflow of air from the street and its exhaust back. For his balance in the house, they must be carried out synchronously.

Classification of ventilation systems

Today, many different types of ventilation systems are known. This diversity is explained by differences in the purpose of the premises, the nature and type of the technological process. Based on this, a classification of ventilation systems was developed according to:

• the way air is moved - artificial and natural;
• purpose - exhaust and supply;
• design - channel and channelless;
• service area - local and general exchange.

Natural ventilation of industrial facilities

Natural ventilation in the room is the most common. It does not require any additional equipment or power supply. With this type of ventilation, the movement of air occurs due to differences in temperature and pressure.

In those buildings where you can observe a large amount of excess heat, the air will be warmer than that which is outside. Cold air will displace warm air from the room, thereby creating its circulation.

Industrial ventilation systems based on natural ventilation function due to different air pressure. At the same time, it should be noted that this difference should not be less than 3 m, the length of the air ducts should not exceed 3 m, and the speed of the air in them should not exceed 1 m/s.

The design of such ventilation is not complicated and does not require the use of additional equipment and electricity. Its effectiveness depends on factors such as temperature and air velocity. In some cases, natural ventilation does not make it possible to solve the problems of effective ventilation, therefore, additional equipment and installation of ventilation of industrial premises is required.

Mechanical ventilation of industrial facilities

Mechanical ventilation in the system requires equipment to move air. Such equipment includes electric motors, fans, air heaters, etc. With its help, ventilation systems provide air supply and removal. If necessary, they can heat the air, humidify and purify it. This distinguishes them from natural ventilation systems. To create comfortable conditions, the ventilation of industrial premises can simultaneously combine both natural and mechanical types of ventilation. It depends on the choice which, in the end, the installation of ventilation of industrial premises will be carried out.

In the case when installation and installation of ventilation is required at the facility, its design, installation depends on the facility, its location and purpose.

Supply ventilation of industrial facilities

Such ventilation is used to supply fresh air from the street and return air from the room in return. In this case, the supply air can be further processed, for example, humidified or heated.

Exhaust ventilation of industrial facilities

This type of ventilation system is used to remove polluted air from industrial premises. They are used where air must not flow from one room to another. For example, in bathrooms, laboratories, catering establishments, warehouses.

As a rule, it is combined with a supply system, because without it, the exhaust ventilation of an industrial facility will not be effective. Although, such ventilation can be installed independently. Two systems can be installed both on all premises and on its separate sections.

In the case when the amount of exhaust air is greater than the supply air, there is a high probability of occurrence of such negative phenomena as drafts. The exhaust ventilation system of the room removes polluted, warm air from certain places, in certain quantities - all this is taken into account when installing the ventilation of industrial facilities. If necessary, this air can be further purified from impurities that should not be released into the environment.

Local ventilation of industrial premises

Such ventilation is designed to provide air to the room through flow ventilation. The exhaust air is then removed by local exhaust ventilation. Usually this type is used in production shops. In residential premises, it can be used when part of it is used as a workplace, where there is significant air heating or the emission of harmful substances.

Local supply ventilation for industrial production

Such ventilation is suitable for open production with the release of harmful substances, if it is not possible to install a local exhaust system.

When is the installation of local exhaust ventilation used in industrial premises?

It is used in rooms where harmful substances are localized and their further spread is preventable. It can also be used in residential areas. In rooms where harmful emissions are present, the local exhaust ventilation system is very important, because it guarantees the removal of harmful substances (gases, smoke, dust) that are emitted by thermal appliances. To remove them, local suctions are used in the systems.

With this type of ventilation, the air that is removed from the workshop must be cleaned before it enters the atmosphere. The degree of purification required depends on the complexity of the device and its design. For optimal cleaning, as a rule, several filters (two or three) are installed during installation.

This type of ventilation system can be called the most effective, since the removal of harmful substances occurs immediately when they are released, preventing their spread in the room.

However, local exhaust ventilation cannot fully solve all the tasks that are assigned to it. It is not able to localize substances released during production if they are distributed over a large area. A similar situation occurs when activities are carried out over the entire area or work with these substances is directly related to their movement. Here, general exchange ventilation systems will be more effective. They are able to remove polluted air evenly throughout the room.

General exchange supply ventilation of industrial facilities

Such ventilation is used to assimilate excess moisture and heat, diluting vapors that have not been removed by other types of ventilation. If there is a lack of heat, then the general exchange supply ventilation is combined with the heating of the supply air or its mechanical stimulation. During its operation, the supply air fully compensates for the harmful substances removed from the room.

General exchange exhaust ventilation in workshops and industrial buildings

Such a ventilation system is an installation that evenly removes air from the room and performs general air exchange. It is suitable for installation in apartments and offices, cottages and country houses. In workshops and industrial buildings with harmful emissions, more complex installations of such a ventilation system are used. In this case, the laying of air ducts is carried out on the floor or in the form of underground channels. If there is a need for general exchange exhaust ventilation, then its design is carried out taking into account all the characteristics of this room.

There are cases when the installation may contain an extended exhaust duct. With a length of such an air duct of more than 30-40 meters, a centrifugal-type fan is installed instead of an axial one.

In the case when various harmful substances, such as dust, moisture, etc., are dispersed in the room, it is not possible to get by with just one ventilation system. Here, general-exchange exhaust ventilation, which remove harmful substances from the air, have proven themselves well in the installation of ventilation of industrial premises.

Ducted and non-ducted ventilation

The ductless ventilation system does not contain air ducts. In it, air exchange is carried out through vents, windows, etc.

It is quite simple and therefore cheap, but ineffective in comparison with the channel system. In a duct system, there must be special channels where air moves to certain places. Both systems are used in apartments, cottages, industrial facilities.
