A ventilation hood (4) comprises a top panel (5) and four walls (6, 6', 7, 7') extending downwardly therefrom. The hood is provided with air exhaust means for evacuating e.g. air smelling of cooking from a preparation or cooking installation below, as well as air supply means for introducing supply air into the air exhaust means. The hood (4) is of given standard design, and both the air supply means and the air exhaust means are separate housings (8, 9) of substantially equal length which is but a fraction of the total length of the hood (4). A plurality of housings (8, 9) are mountable in pairs at optional points along the side walls (6, 6') of the hood, an air supply means (8) being positioned opposite to an air exhaust means (9) in each pair to serve different, optionally disposed preparation units (2, 2') forming part of the preparation installation (1) below the hood (4). |
