The invention discloses a novel double-channel passenger plane cockpit mixed ventilation system. Fresh air introduced by an air entraining system (including engine air entraining, APU or electric aircompression air entraining system) is treated by an environment control system and then led into a mixing tank; after the air is mixed with circulating air from a recirculation system, the air is conveyed to an upper air port and a side air supply port through an upper air port air pipe and a side air supply port air pipe in an air distribution system to enter a passenger cabin, a lower air port is an air return port, one part of return air is exhausted through an exhaust port through a lower air port air pipe, and the other part of return air enters the recirculation system to participate incirculation. The air supply mode is changed into simultaneous air supply from the upper air supply port and the side air supply port.
本发明公开一种新型双通道客机座舱混合通风系统,通过引气系统(包括发动机引气、APU或电动空气压缩引气系统)引入的新鲜空气经过环境控制系统处理,送入混合箱,与来自再循环系统的循环空气混合后,在空气分配系统中分别由上风口风管和侧送风口风管送至上风口和侧送风口进入客舱,下风口为回风口,回风经下风口风管,一部分由排气口排出,另一部分进入再循环系统参与循环。送风方式改变为从上送风口和侧送风口同时送风。
