摘要:The present investigation was focused on the analysis of indoor air quality characteristics of an air conditionedcar using statistical approach. The conditioned space was selected and the experiments were planned asper design of experiments to study the effect of human load, fresh air supply and air velocity on the humancomfort conditions. The nonlinear regression models were developed to predict the comfort conditions namelytemperature, CO 2 level and relative humidity over a specified range of input conditions in this investigation.
