Induced fan built-in high efficiency centrifugal fan, built-in high efficiency centrifugal fan, with a significant low noise, small size, light weight, easy loading (vertical, horizontal may be), easy maintenance features, has been widely used in underground parking complete ventilation field, gymnasium, a large induced fan shop, warehouses, shopping malls, supermarkets, entertainment venues and other large occasions. The main application of the theory of perturbations induced by the fan from the aerodynamic characteristics of high-speed jet, use a small amount of gas injected to induce and disturbing mix a lot of ambient air, and bring it to a specific target direction. Jet center velocity gradually reduced starting from the nozzle exit point, but gradually increase the width of the jet, the amount of air induced around gradually increasing. On the one hand diluted indoor harmful gas, on the other hand led to indoor air flow induced by the fan selection, along a predetermined air flow path travels to the exhaust fan at the exhaust fan inside the room to drain away the fire induced fan, to achieve within the garage Good ventilation. Induced fan air from the high-speed jet nozzle piping sufficiently large spatial diffusion flow stream called the shot. Jet enters the touch device, after a certain space, due to the irregular movement of gas particle jets, especially the lateral pulsating gas particle, resulting in still air with the surrounding medium quality and momentum transfer induced fan, cause or drive around the air flow. Fresh air, ultra-thin air ejector mainstream high-speed spray of induction and stirred a lot of ambient air, on the one hand and harmful gases diluted garage space, on the other hand led to a flow of air along the pre-set direction to reach The purpose of introducing fresh air to air inlet at the mouth of the exhaust gas is discharged smoothly, ensure good ventilation effect garage space.
