In modern laboratory, ventilation system is very important in the whole laboratory. With the progress of science and technology, the original ventilation system has developed into automatic ventilation system. What are the characteristics of ventilation automation in industrial innovation laboratory? Let's take a look at Yichuang laboratory.
 
Difference between original ventilation and automatic laboratory ventilation
The original ventilation system is designed according to the ventilation requirements. The main fan of the air duct operates at power frequency, and the total air volume is basically fixed with the air volume of each outlet. When the system is in normal operation, it can meet the use requirements, and the system can not adapt to the changing situation, so the basic ventilation parameters of the system will change. As the main fan has been operating at power frequency, when the number of tuyeres is reduced, the air volume and wind speed of other tuyeres will increase, which will affect the experimental data of other tuyeres.

 
If the tuyeres are open when not in use, the main air supply will always operate at power frequency, which will lead to a waste of energy. In the experimental process, when some tuyeres need to modify the air volume or wind speed, the system can not automatically deal with it. The old ventilation control system is based on the traditional relay control system. In order to realize the automatic control of ventilation system, it is necessary to rely on some necessary automation products.
The main task of the main engine room is to control the frequency change of the main fan and transmit the running state of the main fan to the display screen of the laboratory. In order to prevent the failure of the display screen, the control screen controls the function of the whole air duct host. The monitoring system can also monitor the current operation status of the main fan of the system by remote control of the equipment operation in the laboratory. Therefore, compared with the original ventilation system, automatic ventilation can control the main functions of the air duct, remotely control the operation of equipment, and assist the monitoring system to save many frequent operations.
The above is the introduction of the advantages of laboratory ventilation automation. With the development of intelligent ventilation system, more and more popular. It can not only be more accurate and safe, but also can promote social progress. It can not only ensure energy saving, but also ensure the safety of use. In order to protect the safety of analysts and prevent the pollutants from diffusing into the laboratory, the ventilation system of intelligent laboratory is still ideal.
