本文针对岭南庭园夏季热舒适状况进行研究。首先,使用现场实测及问卷调研的方法,获得各气象要素(空气温度、相对湿度、黑球温度、风速)的逐时数据及庭园室外热舒适状况;然后,借助Ray Man模型,计算生理等效温度,综合评析庭园不同景观要素组合空间的热环境情况;最后,采用回归分析法建立岭南庭园室外空间人体热感觉与热环境指标之间的关联并获得PET热中性温度及阈值上限,初步建立岭南庭园室外热舒适评价模型。
In this paper, we study the summer thermal comfort in the Lingnan Garden. Firstly, the time-series data of each meteorological element (air temperature, relative humidity, black-ball temperature, wind speed) and the outdoor thermal comfort status of the garden were obtained by means of field measurements and questionnaires. Then, Ray Man’s model was used to calculate the physiological equivalent Finally, using the regression analysis method to establish the correlation between thermal sensation of human body in the outdoor space of Lingnan Garden and the thermal environment index, and obtaining the PET thermal neutral temperature and the upper limit of the threshold, the preliminary establishment of the thermal environment of the garden Outdoor Thermal Comfort Evaluation Model for Lingnan Garden.
