Document Type and Number:
WIPO Patent Application WO/2021/208959
Kind Code:
A1
Abstract:
An air amplifier ventilation system for providing efficient spot cooling in multiple locations for various applications, such as railway station platforms, includes compressed air plants (8) at remote locations, which may be located at one or both ends of the railway station platform, and air amplifier units (1) located at various cooling locations, such as automatic platform gateway doorways located on a railway station platform. Compressed air generated by the plants (8) is provided to the air amplifier units (1) through delivery pipes and respective pressure reducing valves (2). The air amplifier units (1) generate an amplified and evenly distributed air stream via air induction principles and Coanda effect to provide spot cooling based on compressed air, and without the use of conventional bladed fans or physical air movers.
