The invention belongs to the technical field of ship ventilation, and discloses a ventilation diffuser and a ship ventilation system. The ventilation air diffuser comprises an air diffusion shell, a blade set, an adjusting assembly, a first air diffusion piece and a second air diffusion piece. The diffusion shell is provided with an air inlet and an air outlet; the blade group is movably connected to the air inlet; the adjusting assembly drives the blade set to move so as to adjust the communication area of the air inlet. The first flow dispersing piece is provided with a first flow guide space and a plurality of flow guide holes communicated with the first flow guide space; the second flow diffusing piece is provided with a second flow guiding space and a plurality of flow diffusing holes communicating with the second flow guiding space. When the ventilation air diffuser is used, when air flows out of the flow guide holes and the air diffusing holes, the flowing speed is lower than the conveying speed of a ventilation system, noise generated when the air flows into a room is reduced, the living experience of passengers is effectively improved, direct influence on an air flow field in an original exhaust area in a kitchen cannot be caused, and the service life of the air diffuser is prolonged. And the exhaust system in the kitchen can be ensured to exhaust gas smoothly.
本发明属于船舶通风技术领域,公开了通风散流器及船舶通风系统。通风散流器包括散流壳、叶片组、调节组件、第一散流件以及第二散流件。散流壳具有进风口和出风口;叶片组活动连接于进风口;调节组件驱动叶片组活动而调节进风口的连通面积;第一散流件具有第一导流空间和与第一导流空间连通的多个导流孔;第二散流件具有第二导流空间和与第二导流空间连通的多个散流孔。该通风散流器在使用时,空气在从导流孔和散流孔流出时,流动速度低于通风系统输送时的速度,使得空气流入室内时所产生的噪音降低,有效改善乘客的居住体验,而且对厨房内原有的排气区域内的空气流场不会造成直接影响,确保厨房内的排气系统顺利将气体排出。
