Patent ID: 11135897

Abstract:
An air duct system for passing an air flow emanating from an air outlet to a measurement device for detecting parameter measurement values for at least one parameter of the air flow, includes at least one collecting unit for collecting the air flow emanating from the air outlet. That one collecting unit can be disposed on the air outlet so that a contact surface of the collecting unit encloses at least one outlet opening of the air outlet circumferentially. The collecting unit includes a wall defining a continuous air duct with an inlet end section and an outlet end section. In order to improve the measurement of the parameter of the air flow, the air duct system includes at least one measurement chamber that is communicatively connected to a section of the air duct enclosed by the inlet end section, which, as a measurement chamber that is otherwise closed relative to the surroundings, either contains at least one pressure sensor or comprises at least one connection for communicatively connecting the measurement chamber to a pressure measurement device.
