摘要： The invention relates to a method of ventilating a treatment cubicle such as a painting or spraying cubicle used for painting items such as vehicle bodies. The fresh air to be supplied to the cubicle is supplied via an air-permeable ceiling (1); an air supply chamber (2) is provided above the ceiling (1) and communicates with an inlet air chamber (3) which is connected via at least one aperture (4) to a fresh air supply system. The volume of fresh air flowing into the air supply chamber (2) can be regulated by altering the aperture (4). The proposed process is characterized by the fact that at least some of the fresh air drawn into the inlet air chamber (3) is forced to flow in a path parallel to the ceiling (1) for a predetermined distance before passing via the aperture (4) into the air supply chamber (2), while the parameters needed to regulate the fresh air flow are measured in the end region of the directed air stream. The invention also concerns a treatment cubicle. (Fig. 1)

摘要： In a process for drying coated surfaces in a hot-air drier, part of the hot air in the drier is continuously circulated therein as a secondary airstream which is mixed with a primary airstream heated to above the drying temperature Tmax. This reduces the quantity of hot air to be fed into the drier and thus the material requirements are reduced and the heating time shortened. A hot-drier for implementing the process has, in the hot-air chambers (7, 8) arranged symmetrically on either side in the interior (6) of the drier, a separating wall (22) dividing an internal chamber (7) and an outer chamber (8) which has an intake aperture (9) at its lower end for secondary air. At the lower end of the inner chamber (7), the primary air is fed in at a higher flow rate and mixed with the secondary air taken in through the aperture (9).
