Impinging jet ventilation has sufficient supply momentum to overcome thermal buoyancy, with the potential reduce cross-infection risk in winter. Using an Eulerian-Lagrangian approach validated by experiments, this study compared exhaled particle dispersion a two-bed hospital ward heated impinging and mixing ventilation. Exhaled particles ten different diameters were tracked under four typical air changes per hour. Particle concentration distribution residence time compared.

Container farms (CFs), a controlled environment agricultural technology designed to solve food insecurity, are receiving increasing attention from researchers. However, the complex geometric structures and artificial lighting used in CFs present challenges effectively controlling thermal environment. This study aims identify primary factors that impact of while conducting factor ranking significance analysis, providing theoretical basis for future optimization. The research method CFD simulation, an orthogonal experimental design were adopted achieve above objectives. Theoretical analysis revealed influencing HVAC system’s supply air temperature, humidity, flow rate, light source used. Four evaluation indices, including mean value range between layers temperature moisture content, results significant humidity content. In case layers, rate display correlation. These findings suggest optimization should prioritize regulation source.
