Abstract
Long-term exposure to indoor high temperature and high humidity environment can lead to heat disease. In order to evaluate the heat stress level of human body in indoor high temperature and high humidity environment, the present study used CRITIC combination weighting, established a new comprehensive evaluation index CRI based on TOPSIS model, verified the rationality of CRI, and determined the classification of CRI by the thermal stress intensity classification of physiological stress index PSI. The results showed that the weight of thermal sensation vote, tympanic temperature, oral temperature, average skin temperature and heart rate was higher, which was greatly affected by high temperature and high humidity environment, and the weight of systolic blood pressure and diastolic blood pressure was lower. The safety range of CRI (0.56,1], heat tolerance range (0.23,0.56], dangerous range [0,0.23].
