Research and Development of Environment Simulation System Based on Large Hybrid Low-pressure Chamber

Objective To simulate the environments with different conditions of high temperature,low temperature,drying,heavy ultraviolet radiation or with combined above conditions.Methods Refrigeration,heating,ultraviolet radiation were used independently or comprehensively to simulate different natural environments.Results When the low-pressure chamber was located from the ground to some altitude less than 10,000m,the temperature in the heat temperature was from normal temperature to 48℃ or 52℃,the one in the low temperature chamber was from-52℃ or-48℃ to normal,the humidity was between 13% or 7% RH and normal condition,and the ultraviolet radiation intensity was from 40 to 70W/m2.Conclusion The low-pressure chamber can be used for the simulation of several complex natural environments to perform medical experiments and medical service researches at wartime and peacetime.
