摘　　要：西藏高原冬季漫长、年平均气温低、昼夜温差大,如何保障在高原极端气候下的宿舍供暖是亟需解决的难题,暖床末端系统具有分区供暖、精准高效的特点,可以有效满足高原校舍类建筑的供暖需求.通过实验研究了不同加热形式和不同设定温度对暖床供暖性能的影响,采用单位功耗下的温升速率作为评价指标,得到了暖床末端与其他常用取暖装置的供暖效果对比结果.结果显示:电加热暖床对于床板和被褥的升温幅度约是水加热暖床的2倍;与其他常用取暖装置相比,电加热暖床和水加热暖床的相对温升速率分别提高了143%、68%,研究为暖床在西藏高原校舍的应用提供了实测基础数据.The Tibetan Plateau has a long winter,low average annual temperature and large temperature difference between day and night,so how to ensure the heating of dormitory in the extreme climate of the plateau is an urgent problem to be solved.The warm bed terminal system has the characteristics of zoned heating,precision and high efficiency,and can effectively meet the heating needs of plateau dormitory buildings.In this paper,the effects of different heating forms and different set temperatures on the heating performance of the warm bed are studied experimentally,the temperature rise rate per unit power consumption is used as the evaluation index,and the heating effect of the end of the warm bed and other commonly used heating devices is obtained.The results shows that the heating amplitude of the electrically heated bed for the bed board and bedding is about twice that of the water-heated bed.Compared with other commonly used heating devices,the relative temperature rise rate of electrically heated bed and water-heated bed warmer are increased by 143%and 68%,respectively.The study can provide measured basic data for the application of bed warming in dormitory buildings on the Tibetan plateau.
