In the pharmaceutical industry, it is important to ensure the cleanliness and safety of the space at all stages of the development and production process. Fume hoods are often used for this purpose, which provide a suitable working environment in a smaller volume and enable safe work with hazardous substances. The fume hood and flexible membrane walls require flow control at a constant pressure difference. This prevents dust particles from entering the device. Blowing is carried out with the help of special blowers, nozzles and flaps that need to be controlled.
The master's thesis presents the development of a fume hood ventilation system consisting of a blower, dampers and nozzles and their control. The control must be simple and manually controlled, while ensuring a constant pressure difference to form a flexible membrane shape at the desired flow rate change. The manufactured ventilation system will be used in a real environment to suck disinfectant from the device. To design the system, the first step is to review the standards, followed by the presentation of concepts, construction of the selected and testing of the prototype system. The Nucleo development board is used as an upgrade to the manually controlled system.
