Effects of Sudden Changes in Indoor and Outdoor Radiation Intensity on the Human Thermal Response During Winter At High Altitude
Solar radiation is stronger on the Tibetan Plateau than at lower altitudes at the same latitude.Under the sudden change of indoor and outdoor radiation,the demand for indoor thermal environment of the plateau population is different from that of indoor steady-state environment and has not been accurately described.This paper conducted on-site research on Tibetan migrants and Tibetan residents,and classified the intensity of outdoor radiation on the plateau to characterize the thermal responses of the two populations.The results showed that the heat-neutral temperature demand of the plateau population entering the room from outdoors with different radiation intensities was different,and differed from the heat demand of the indoor population in the steady-state environment.The heat-neutral temperatures of the incoming Tibetan population entering the room from outdoors under different radiation conditions were 23.5 ℃(weak),21 ℃(medium),and 17.9 ℃(strong),with the heat-neutral temperature under the strong radiation group being lower than that in the indoor steady-state environment(19.2 ℃),and the heat-neutral temperatures under the weak and medium radiation being higher than that in the indoor steady-state environment.Therefore,the conclusions of this study can provide a reference for the thermal environment regulation strategy of buildings in regions with strong solar radiation,such as the Tibetan Plateau.
