Abstract

The present application relates to the field of laboratory ventilation, in particular to an intelligent control system for laboratory ventilation variation, which includes an exhaust device, an air intake device, and a controller, and the controller is installed on the wall of the laboratory. There is an air outlet on one wall of the laboratory, and an air inlet on the other wall. The exhaust device is installed at the air outlet of the laboratory. The exhaust device includes an exhaust fan, a purification component, and an air volume detection component. The exhaust fan and air volume detection components are electrically connected to the controller, and the air inlet device is installed at the air inlet of the laboratory. The air inlet device includes an air inlet fan, which is electrically connected to the controller, and the air inlet and outlet of the laboratory are provided with an air outlet adjustment component, and the air outlet adjustment assembly is electrically connected to the controller. The application is convenient to accurately control the ventilation volume of the laboratory, thereby improving the effect of exhausting and purifying toxic gases.

Description

technical field [0001] The present application relates to the field of laboratory ventilation, in particular to an intelligent control system for laboratory ventilation variation. Background technique [0002] Some chemical experiments in the laboratory usually produce a certain amount of toxic gas, so the laboratory usually installs a ventilation system to discharge the toxic gas in time for purification, maintain a normal indoor air environment, and ensure the safety of experimenters. [0003] If the ventilation volume of the laboratory is too high, the toxic gas will be turbulent in the laboratory, and it cannot be discharged in an orderly manner for purification treatment. If the ventilation volume is too small, the toxic gas cannot be discharged in time for purification treatment. When carrying out different levels of chemical experiments, the amount of toxic gas produced is different, so it is necessary to adjust the ventilation volume of the laboratory according to th...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the experimenters adjust the ventilation volume by manually adjusting the size of the air inlet and outlet in the laboratory, which is inconvenient to operate and the ventilation volume cannot be precisely controlled.
