摘　　要：为研究寒冷地区过渡季高校内短期热经历对教室内的热舒适与热适应特征,选取西安地区某高校为研究对象,对过渡季教室内的热环境参数进行测量,同时调查了307名学生在经历了短期热经历后对教室内热感觉和自我学习效率的主观评价。结果表明:受短期热经历影响的预计中性温度为25.8℃,实测热中性温度为22.7℃,两者相差3.1℃,表明在短期热经历的影响下导致了更低的中性温度,得到短期热经历影响期间的适应性预计平均热感觉(aPMV)。通过学生对学习效率和学习热情的投票变化进行分析,得出:在短期热经历时长为>5~10 min时,学生的学习效率和学习热情受到影响的人数比例最大;在短期热经历时长为0~3 min时,学生的学习效率和学习热情受到影响的人数比例最小。学生对室内的温度期望变化影响室外空气舒适度和满意程度的预期评价。To study the thermal comfort and adaptation characteristics of short-term thermal ex-periences in universities during the transition season in cold regions,a university in Xi’an was se-lected as the research object to measure the thermal environment parameters in classrooms during the transition season.At the same time,307 students were surveyed for their subjective evalua-tions of classroom thermal sensation and self-learning efficiency after experiencing short-term thermal experiences.The results show that the expected neutral temperature affected by short-term thermal experience is 25.8℃,while the measured thermal neutral temperature is 22.7℃,with a difference of 3.1℃.This indicates that the influence of short-term thermal experience has led to a lower neutral temperature.Through research,the adaptive average thermal sensation(aPMV)during the influence period of short-term thermal experience was estimated.By analy-zing the changes in students'voting on learning efficiency and learning enthusiasm,it is found that the proportion of students'learning efficiency and learning enthusiasm is the highest when the short-term hot experience duration is>5~10 min,and lowest when the duration is 0~3 min;The students'expected changes in indoor temperature affect the expected evaluation of outdoor air comfort and satisfaction.The conclusions provide a reference for the study of the im-pact of short-term thermal experiences in universities on thermal comfort and adaptation in class-rooms.
