不同供暖模式下居住建筑热环境与能耗分析
Building thermal environment and energy consumption for residential building in different heating modes
摘要：
针对北京某居住建筑的典型户型，采用TRNSYS模拟软件，对3种不同供暖模式下建筑热环境与能耗进行了研究。结果表明：白天停止供暖时，房间最大温降为7.15 ℃，室内温度最低达到10.85 ℃；与连续供暖相比，间歇供暖可减少建筑耗热量，其中夜间所有房间保持供暖可减少能耗6.20%，夜间分时分区保持供暖可减少能耗17.40%；为了保持设定温度，间歇供暖需要加大供热设备容量；采用间歇供暖时，夜间建筑墙体内表面温度较连续供暖低，其对人们热舒适感的影响需要进一步研究。
Abstract：
Analyses the building thermal environment and energy consumption of a typical apartment in Beijing in three heating modes using the TRNSYS simulation software. The results show that when heating ceases during the day, the highest temperature drop is 7.15 ℃ and the lowest temperature reaches 10.85 ℃. Compared with continuous heating, intermittent heating can decrease the energy consumption. In the heating mode that all the rooms cease heating in daytime and resume heating at night, the ratio of energy saving is 6.20%, while this ratio can be up to 17.40% in the heating mode that all the rooms cease heating in daytime and adopt time-sharing district heating at night. It is necessary to increase the heating equipment capacity in order to keep the set temperature of the rooms. When adopting intermittent heating mode, the temperature of inner wall surface is lower than that in continuous heating mode, and further study should be carried out on their influence on the people’s thermal comfort.
