Ventilation automation - technical tasks, requirements, installation and commissioning

Automation of ventilation systems

Ventilation in public and industrial buildings is necessary to remove polluted or highly heated air and supply clean air with specified temperature and humidity parameters.

At the same time, air exchange and air flow rate are determined according to regulatory requirements depending on the type of premises, the technological processes performed and the intensity of pollution.

The use of automation to control the operation of ventilation allows you to optimize their operation and ensure effective air exchange in the premises to create comfortable conditions during the stay of people.

Therefore, the availability of automation is of great importance on large and branched ventilation systems. industrial enterprises, public buildings, sports complexes, train stations, airports and other large structures. Correctly selected and adjusted set is able to provide the most efficient and uninterrupted air exchange in any room.

Technical tasks performed using automation

Ventilation automation provides for the installation of monitoring, control and executive elements. They work together to control temperature, humidity, air speed and pressure within ventilation chamber, in air ducts, on air distribution devices and directly in serviced premises.

Correctly designed, installed and adjusted scheme of automatic control of ventilation of premises or working areas allows you to solve the following tasks:

• monitoring of control climatic indicators and constant monitoring of the operability of the main ventilation equipment;
• preservation of data on the operation and parameters of the supplied air for a long time;
• automatic maintenance and change of the modes of air supply to the serviced premises;
• switching on and off additional ventilation units, depending on changes in microclimatic conditions, the actual degree of load, time of day and other changing conditions;
• automatic changeover to summer or winter operating mode;
• monitoring the level of pollution of air filters, recuperators, air heaters and other equipment;
• ensuring system shutdown in the event of a short circuit to prevent more serious damage;
• joint work with fire safety systems and turning off the air supply when a fire source is detected;
• the ability to switch to manual control of work.

As additional elements of automated control, the presence of remote wireless controller to make the necessary adjustments to the operation of the ventilation systems. Such control can be carried out via the Internet, Wi-Fi or Bluetooth. As a result, the control of the automatic system will become simple and convenient.

Features of industrial ventilation systems

Large branched ventilation systems of industrial workshops are distinguished by large volumes of air exchange and the need to distribute air to separate working areas. At the same time, the climatic parameters of individual zones can differ significantly.

Therefore, the automatic air distribution system can provide for the control of equipment not only in the ventilation chamber, but also on the air distribution devices. For this, sensors must be installed in the serviced work area that monitor the temperature and humidity of the air, and, if necessary, the speed of the air flow.

The organization of regulation can be carried out by changing the performance of the fan, air heater, irrigation chamber and the installation of executive drives on the air distribution grilles.

Requirements for the automation project

Long-term effective operation of an automated ventilation system can be ensured by developing a project that provides for the ability to perform all the necessary tasks.

The design of such systems requires certain engineering knowledge and therefore the correct design of the project can performed only by a specialist of the appropriate profile who has experience in using equipment from different manufacturers.

All automation devices are divided into three large groups:

• sensors that collect information about the state of the system and air parameters, and transmit it for processing;
• controllers and regulators that collect all information from sensors, process it and provide signals for execution;
• executive mechanisms that ensure the execution of commands coming from the regulators.

The main task of the project is to draw up an automation scheme, which, when three groups work together devices will provide effective air exchange to create comfortable conditions in the room during your stay of people.

Installation and commissioning

Modern technologies make it possible to create very complex automatic ventilation control systems. Therefore, their installation and subsequent adjustment, even if there is a well-developed project, must be carried out by professionals. Any installation errors can lead to disruption of air exchange and create conditions for the impossible stay of people in the serviced premises.

An equally important issue will be the start-up and commissioning works. At this stage, the quality of ventilation as a whole is checked and all indicators are brought in line with the design task.

As a result, the correct operation of ventilation will ensure the creation of comfortable microclimatic conditions in rooms or separate zones. The use of modern technology gives significant advantages, providing faster execution of the necessary commands and freeing up the operating personnel. This provides for the possibility of round-the-clock uninterrupted work.
