Numerous places utilize ventilation systems. Offices, sports arenas, production halls, conference rooms, and other spaces are ventilated with their help. These systems typically include additional features for conditioning the air in the room in addition to the air duct system. Filters and other components for sound absorption or air purification might also be present. This training looks at different ways to disperse air within a structure. A fan with a speed controller supplies air to the air duct system. Using commercial parts including pipes, disk valves, bends, branches, filters, and bends, the trainee builds variable air duct systems. Anywhere can have connections put for measuring pressure. Examined are the impacts of each component on the pressure loss and, consequently, the air’s velocity and flow rate. Two manometers with varying measuring ranges and a manual air velocity measurement instrument are available for this purpose. Additionally, the fan’s characteristics are ascertained, and its power consumption is quantified.
