Buildings cannot be imagined without a system that forcibly provides ventilation to the room. In the process of ventilation, the contaminated air stream exits and is completely or partially replaced by a clean one. Automation of ventilation makes it possible to organize control of process control, which, in turn, helps to secure the structure and ensure energy efficiency. Ventilation automation varies, so in this article we will tell you what their purpose is and what is special about them, as well as what characteristics.
Purpose of the system automatic
To date, the ventilation complex has been completely modernized and is a complex instrumentation system with a power plant, air heaters and channels providing a microclimate of the room. In order for all components and assemblies to work together, modern engineers provide the system with equipment with sensors and mechanisms. It is due to them that you can control the ventilation in the assembly.
Tasks of the ventilation system:
- Management and monitoring of system parameters: signal breakdowns, unsafe modes and other unforeseen operating moments. Modern controllers are connected with the operator in real time. This allows the operator to monitor the operation of all system indicators and establish their compliance with the desired mode.
- An individual analysis of the development of any mechanism and process in general according to the specified parameters through monitoring. The control unit receives data obtained with the help of sensors and conducts research with computing power. If necessary, makes adjustments to the overall performance through the signal of the operating mechanics or through the start-up system.
- Protection of the valve part and water circuits of the heating element from freezing. The system thermostat monitors the temperatures of the heaters, not allowing to fall below a critical point.
- Workflow management through mode switching. This is necessary for the rational use of the automatic system in connection with a change in the load on the room, weekly daytime, time of day or climatic conditions. Programs for automatic control of the ventilation system, based on monitoring information, have the ability to use power plants as an addition, complete activities or change the speed of the fan blades, start and stop air dryers, and so on.
- Locking the mechanism in the event of a short circuit or any emergency associated with electronics to prevent a possible fire.
Automation in the ventilation system has a key role and performs a number of necessary tasks, without it it is impossible to perform all of the listed options by the staff.
The main nodes of auto ventilation
The design of an automatic ventilation system requires a rather laborious and complex work of engineers, such a process requires not only theoretical knowledge, but also a lot of experience.
Necessary knowledge:
- similar system structure;
- main parts and main units;
- logical performance and the totality of all parts and devices.
In order to apply the most optimal instrumentation for the system and control it, it is imperative to take into account the nomenclature of excellent manufactures, as well as have operational experience with such equipment. It will also be useful to study user reviews in order to understand the price-performance ratio of the model today.This will allow you to purchase a quality system on favorable terms.
The latest ventilation systems are equipped with any type of equipment - digital and analog, it includes three basic groups:
- Touch dashboards and sensors. The group contains various tools for the information set about the current state of the complex, starting from the type of temperature, pressure, moisture content in the air, current strength, etc. The collected information is transformed into an electrical signal and fed to the controller input.
- Controllers with regulators are part of a group that collects and conducts analytics of sensor data. Then, based on the analysis, it issues an order to the circuit breaker or executive mechanics, while changing the operating mode in whole or in part. The assembly of controllers is possible both analog (based on analog logic circuits) and digital (based on digital technology with software).
- Executive mechanization includes varieties of drives, regulatory bodies and other mechanisms through which controllers transmit commands to change parameters. Acting mechanics are: automatic valves of the supply system, servo drive (servo drive), current cut-off switch, frequency regulator of rotor speed in an electric motor, etc.
A design of any complexity is necessarily equipped with the above-mentioned auto-ventilation nodes, but additional ones can be installed to them - it all depends on the scale of the system.
The advantages of such a system
Thanks to innovations in the field of electronics, engineers became subject to the creation of complex logical tasks. And also the solution of multi-stage tasks of a complex nature, through technology and electronics, without involving a person. All systems of the new generation are assembled with an automatic system, because today it is no longer possible to do without it. No operator can cope with tracking all the parameters and nuances of work. And, of course, he cannot afford to make decisions on their immediate elimination, at a time when the automatic complex does this clearly and in a timely manner, eliminating any human factor.
Checking the ventilation:
- automated system functionality;
- regulation and control of the frequency of rotation of the fan blades;
- water intake temperature control and frost resistance of the air heater;
- observation of air volumes in a ventilated building in order to control the system to create a microclimate;
- detection of contamination of the filter set to notify of a replacement;
- transferring the whole mechanism or its part to the “sleep” option and activating nodes from this mode on time, following the program;
- providing protection against overloads of a power supply network and short circuit of wires;
- analysis of the system status and operating modes, with information output to the display;
- the ability to manually control to configure the equipment.
The entire process, from the project to the completion of the installation, is a very complex procedure, so you should only contact highly qualified specialists in this field.
