| Popis: | Indoor solar radiation notably affects the thermal environment and the character of human heat exchange with the ambient environment. Based on the field experiments of human body thermal comfort under indoor solar radiation in winter, this paper analyzes heat exchanges between the human body and the surrounding environment and the local and overall skin temperature, and discusses the relationship between heat exchange and thermal sensation. The results show that the skin temperature of the left upper arm and left thigh under radiation is 3.3 °C and 2.0 °C higher than that without radiation. As the irradiated area increases, convection and evaporation heat loss increase, and total heat loss decreases. When the thermal sensation of the human body is in a neutral state, the proportions of heat loss by convection, radiation and evaporation are 33.9%, 47.1% and 10.4%, respectively. |
