Abstract: An exemplary ventilation air mixer includes a branch air duct and a trim air mixer. The branch air duct has an inlet that is configured to be coupled to a takeoff port of a main air source duct. The branch air duct has multiple holes arranged about a wall of a mixing portion. The trim air mixer at least partially surrounds the branch air duct and forms a cavity extending from the inlet of the branch air duct to at least the mixing portion. The trim air mixer has a trim air source duct connection coupled at an angle about a midsection. The angle is substantially acute relate to a longitudinal axis of the branch air duct such that trim air entering into the trim air mixer via the trim air source duct connection is directed toward the inlet of the branch air duct.

Abstract: Example ventilation air mixers and example air conditioning systems including ventilation air mixers are provided. One example ventilation air mixer comprises a branch air duct having an inlet that is configured to be coupled to a takeoff port of a main air source duct. The branch air duct has multiple holes arranged about a wall of a mixing portion. The trim air mixer at least partially surrounds the branch air duct and forms a cavity extending from the inlet of the branch air duct to at least the mixing portion. The trim air mixer has a trim air source duct connection coupled at an angle about a midsection. The angle is substantially acute relate to a longitudinal axis of the branch air duct such that trim air entering into the trim air mixer via the trim air source duct connection is directed toward the inlet of the branch air duct.

Abstract: A fluid flow restrictor device for controlling fluid flow at a connection between ducts may include a restrictor device body that is partially or fully inserted into and disposed within one of the ducts and an outboard restrictor device flange extending radially outward at an outboard end of the restrictor device body and having an outboard flange outer diameter that is greater than an inner diameter of the ducts so that the restrictor device body or the outboard restrictor device flange is engaged by an open end surface of the duct to prevent full insertion of the fluid flow restrictor device into the duct. A body inner surface defines a restrictor opening through the restrictor device body that can be varied to achieve desired fluid flow characteristics at the connection.
