Thermal environment inside mobile medical shelters

Objective:To analyze the distribution of air thermal field and velocity field inside mobile medical shelters and to redesign a reasonable thermal environment in them.Methods:A numerical simulation method that is based on the computational fluid dynamics (CFD) and finite element method (FEM) was established to predict the thermal environment inside the shelters.The rationality of this method was verified by test results.The thermal environment inside the shelters was designed according to the air_conditioning theories and that simulation method. Results:The forms and distribution of airflow, the thermal field and the velocity field inside the shelters satisfied the requirements of thermal standard.Conclusions:The simulation method is rational and feasible.The designed thermal environment inside the shelters will benefit the improvements in personal comfort and medical operation effects.
