Research on atmospheric environment control of local double-layer working chambers

First, the model was established using the numerical simulation software CFD, and the two turbulence models, respectively, were analyzed and compared and studied. It was found that the standard k-\(\varepsilon\) model was more reliable, and the correctness of the model was verified. Then, the temperature distribution of the local double-layer working chamber was numerical simulation to analyze the results of the atmospheric environment control scheme of the local double-layer working chamber. The use of centralized air conditioning air supply method or independent air conditioning air supply method cannot meet the cabin temperature control requirements well, and the overall environment of the cabin is poor. By optimizing the cabin air conditioning solution and adopting a combination of independent air conditioning and air conditioning air supply, the average cabin temperature can be controlled at 24.9℃, which can well meet the cabin temperature control requirements. The simulation results provide a reference for the design optimization of atmospheric environment control of local double-layer working chambers in the ship.
