Example of grille selection 8

Curvilinear Blade Supply Air Grilles Description The Series 26 curved blade grilles are especially designed for providing any type of discharge: from the absolute horizontal airstream to the complete vertical airstream, regardless of whether they are ceiling or wall mounted. The grilles can be used in cooling as well as heating systems, given the great discharge airstream control flexibility of their blades. The curvilinear blade supply air grille is especially recommended for rooms with a difficult air distribution. Its curvilinear blades reduce air currents and even ensure air spreading. They...

Arrangements Arrangement

The data listed in the selection tables have been determined using arrangement (a) as a baseline (refer to page 3). For other arrangements, apply the correction factors in Table 1. All these values correspond to a temperature gradient between the supply and room air of 10 C. During the cooling process, the throw will slightly decrease while the drop will increase. On the contrary, in the heating process, the throws will slightly increase. Maximum: It is the distance in m (measured in a plane parallel to the grille) from the centre of the grille to a point in which the residual velocity is 0.25...

Applications Wall applications In heating operation, it is recommended that the discharge velocity does not exceed 1.5 m/sec. In cooling operation, the maximum throws must be equal or greater than the distance from the grille to the ceiling. Free space: The grille is considered to be located in a free space when the maximum throw is reached at a point between 3/4 and the total distance to the nearest wall. The airstream drop in cooling operation will not be excessive if the supply air flow is less than what is indicated in Table 3. When the grille is installed detached from the ceiling, e. g....
