To observe human overall and localthermal sensations in dynamic thermal conditions, a series of experiments under variousconditions were carried out in a cabin-likeclimate chamber. The results showedthat the head, chest, back, and hands during hot exposure are warmer leading to theoverall thermal sensation being hot. The thermal sensation of the head was warmerthan the overall thermal sensation. During cold exposure, arms, hands, legs, and feetwere the main areas causing coldness. In a dynamic thermal environment, the previousskin temperature state and thermal sensation form a thermal sensation overshoot,causing a shift in the body's neutral temperature point. This study proposesa thermal sensation model for the prediction of human thermal sensation local andoverall based on skin temperature changes in a dynamic environment. Consideringthe airflow characteristics in the cabin, the human body is set into seven local parts inthe local thermal sensation model. To compensate for sensation overshoot from this,defining recovery points rp for local parts differentiate temperature setpoints accordingto the experienced thermal state so that the effect resulting from the dynamiccondition is integrated into the model algorithm. The model provides a scientific basisfor guiding design optimization and intelligent regulation in the dynamic environmentof the vehicle cabin, so as to achieve efficient energy utilization. 收起
