Study on prediction model of thermal sensation under local draft in low pressure environment

Local draft experiments were conducted to establish the overall thermal sensation prediction model under low pressure environment. Head, chest, hand, and ankle exposed local airflow three environments: 1 atm, 0.87 0.74 respectively. The skin temperature was measured subjective questionnaires collected. results showed that in cooler environment, mean decreased with decrease of pressure, people maybe more sensitive. When environmental decreased, correspondingly. Compared normal condition, as weight on changed a little. chest while hands increased. draft, four body parts similar influence lower conditions. Based temperature, speed, for each part established indicated predicted values highly correlated values. models could be used predict who are
