Hey, I’m new here and not sure if this is the right channel, but I’m looking for some input on an airflow problem. I’m currently designing a small closed-loop plant growth chamber. My background is mainly mechanical design, so airflow design and CFD are not areas I usually work with in depth. The HVACD unit sits above the growing area and, when running, draws air from the chamber, conditions it and returns it back into the same chamber. A nutrient tank sits below the plants, so additional circulation hardware can realistically only be placed on the side walls or in the corners. The main goal is good air circulation around two dense plants, avoiding stagnant humid areas and getting good temperature and CO2 mixing. The second image shows one idea with fixed 45° corner modules, but I’m not sure if that is the best layout. Ideally I’d prefer a fixed, integrated system instead of movable fans. It also needs to remain accessible and easy to clean. Has anyone here worked with plant growth chambers, environmental chambers or similar systems and has experience with internal air circulation layouts? Thanks!
