Title:
SPRAYING BOOTH AND CIRCULATION SYSTEM FOR A WORKING CHAMBER
Document Type and Number:
WIPO Patent Application WO1998028088
Kind Code:
A3
Abstract:
In vehicle spraying booths (1), air is supplied to and discharged from the inner chamber (1a) by an air feeding device. The air supplied is conditioned so that its temperature lies in a desired temperature range and air pollution limit values can be ensured for a person working in the inner chamber (1). A displacement device (10) with a vehicle receiving region that can be moved in at least one direction of displacement in the spraying booth (1) is arranged in the spraying booth (1). This reduces the required booth width to the sum of the width required for working and the width of the vehicle being sprayed, and the required booth length to the length of the vehicle being treated. In order to direct air between the air feeding device (20) and desired areas of the chamber, at least two air supply regions (21b, 23b; 21b', 23b') in communication with ducts (21-23) of the air feeding device (20) and provided with closable openings (18) into the inner chamber (1a) are located in at least one horizontal chamber delimiting region. The openings (18) open into uniformly distributed areas of the chamber. Openings (18) of each air supply zone (21b, 23b; 21b', 23b') are located in each area of the chamber, and thus each area of the chamber can communicate with each air supply zone (21b, 23b; 21b', 23b'). The smaller size of the booth and the directed air currents make it possible to reduce fresh air throughput and the energy required to heat the fresh air.
