Abstract
The study aims to investigate the thermal comfort requirements in residential buildings and to establish an adaptive thermal comfort model in the cold zone of China. A year-long field study was conducted in residential buildings in Xi’an, China. A total of 2069 valid questionnaires, along with indoor environmental parameters were obtained. The results indicated occupants’ thermal comfort requirements varied with seasons. The neutral temperatures were 17.9, 26.1 (highest), 25.2, and 17.4 °C (lowest), and preferred temperatures were 23.2, 25.6 (highest), 24.8, and 22.4 °C (lowest), respectively for spring, summer, autumn, and winter. The neutral temperature and preferred temperature in autumn are close to the neutral temperature in summer, while the neutral temperature and preferred temperature in spring are close to that in winter. Besides, the 80% and 90% acceptable temperature ranges, adaptive thermal comfort models, and thermal comfort zones for each season were established. Human’s adaptability is related to his/her thermal experience of the current season and the previous season. Therefore, compared with the traditional year-round adaptive thermal comfort model, seasonal models can better reflect seasonal variations of human adaptation. This study provides fundamental knowledge of the thermal comfort demand for people in this region.
摘要
本研究旨在调查中国寒冷地区居住建筑的热舒适需求,并建立适应性热舒适模型。由此进行了长期的现场研究,共获得有效问卷2069 份。春夏秋冬的中性温度分别为17.9 °C、26.1 °C(最高)、25.2 °C 和17.4 °C(最低),偏好温度分别为23.2 °C、25.6 °C(最高)、24.8 °C 和22.4 °C(最低)。秋季中性温度和期望温度与夏季中性温度相近,春季中性温度和首选温度与冬季中性温度相近。人们适应性的季节变化既与当前季节气候特征有关,也与前一季的热经历有关。本文建立了各季节80% 和90% 的可接受温度范围、适应性热舒适模型和热舒适区。与传统的全年适应热舒适模型相比,季节模型能更好地反映人类适应的季节变化。
