Abstract

The node point incorporates inlets (6), each of which accommodates the one end of one of the inlet channels, and at least one outlet (7), which accommodates the at least one outlet channel. The node point (1) incorporates an outer shell (2), in which the inlets are arranged; an inner shell (3), which is coaxially arranged in relation to the outer shell for forming a space (8) between them; the inlets being angled in relation to the outer shell for causing the ventilation air to rotate in the space. The central axis in each inlet forms an angle alpha less than or equal to 45 deg. with a tangent to the outer shell. The tangent contact point coincides with the point where the central axis meets the outer shell cover surface. The outlet is arranged in the outer shell and its centre line forms an angle beta less than or equal to 45 deg. with a tangent to the outer shell.
