Prediction of human thermal sensation based on improved PMV model

Abstract

In the traditional PMV model, the calculation of human skin temperature is only related to the level of human activity. In fact, human skin temperature is related to many factors such as evaporative heat dissipation, radiation and convective heat transfer of human skin. Therefore, it is necessary to introduce human thermal physiological model to modify the skin temperature in PMV model. In addition, considering the impact of human activities on human metabolic rate, the formula of calculating human metabolic rate obtained from Pandolf was introduced to improve the original PMV model. Finally, the model is validated and analyzed with published experimental data. The results show that the improved model can accurately predict the thermal sensation of human body under the test condition, and the predicted thermal sensation is closer to the experimental value than the original PMV model.
