Supply air terminal assembly for the supply of supply air to a room, the supply air terminal assembly comprising two throttling units ( 21, 31, 22, 32 ), which are supplied with supply air from a supply air pipe ( 3 ), each throttling unit being formed in order to give the passing supply air flow a preselected pressure drop under weak noise generation, one of, the first, throttling unit ( 21, 22 ) having a preconnected shut off valve ( 40, 44, 45 ) which normally is closed, and which is arranged to be reset into an open position ( 40 ') for temporary enhancement of the supply air flow through the supply air terminal assembly. In the closed state, the valve ( 40, 44, 45 ) is arranged to connect the two throttling units in series in the flow direction of the supply air, the first throttling unit ( 21, 31 ) being located downstream the second throttling unit ( 22, 32 ), and in the open state connects the two throttling units in parallel. |
