AIR SUPPLY SYSTEM

摘要

An air supply system (200, 300) for providing a clean air flow (250) in a room (1) is provided. The air supply system (200, 300) comprises a first air supply section (120) through which a first flow of clean air is supplied with a lower temperature than the temperature of the ambient air in the room (1), and a second air supply section (230) through which a second flow of clean air is supplied. The first air supply section (120) is arranged to form a gravitationally induced downward flow, whereas the second air supply section (230) is arranged to adjust the velocity (vi) of the second flow of clean air when entering the second air supply section (230) to a predetermined velocity (v2), and is adapted to direct the second flow of clean air downwards. A method (600) for providing a clean air flow in a room is further provided.

1. An air supply system for providing a clean air flow in a room, the air supply system comprising:
a first air supply section through which a first flow of clean air is supplied with a lower temperature than the temperature of the ambient air in the room, a second air supply section through which a second flow of clean air is supplied, wherein the first air supply section is arranged to brake the initial velocity (v1) of the first flow of clean air when entering the first air supply section, whereby the first flow of clean air thereafter forms a gravitationally induced downward flow, wherein the second air supply section is arranged to adjust the velocity (v1) of the second flow of clean air when entering the second air supply section to a predetermined velocity (v2), and adapted to direct the second flow of clean air downwards, and wherein the first air supply section and the second air supply section are situated in the ceiling in the room, the first air supply section at least partly surrounding the second air supply section.
