Evaluation of Thermal Comfort in Hyperbaric Oxygen Chamber

Indoor thermal environment of a hyperbaric oxygen chamber was researched by computational fluid dynamics to figure out the relationship between the inlet angle with thermal sensation index. Steady k-epsilon turbulence model and incompressible fluid flow of constant property have been considered, the heat dissipation due to the viscous force was ignored. The results show the air temperature field and flow field are largely affected by inlet angles. High air velocity can enhance the effect of convective heat transfer, and it may causees draught. Even a small change in inlet temperature will cause a great impact on thermal comfort index. Appropriate refrigerating capacity and matching inlet angle are the prerequisite of a satisfactory thermal comfort.
