分时分区毛细管辐射供暖模式下农村建筑室内热环境与能耗研究

针对北京一典型农村合院建筑,采用TRNSYS对其采用毛细管辐射分时分区供暖模式时的室内热环境与建筑能耗进行了研究。结果表明,采用毛细管辐射供暖时,停止与恢复供暖后房间温度变化较快。在最冷日采用分时分区供暖模式时,停止供暖后房间温度最低降至约12℃。综合全年统计,采用分时分区供暖模式各房间有人活动的时段温度达标率仍能保持90%以上,建筑全年总能耗可降低约8.83%。

Study on Indoor Thermal Environment and Building Energy Consumption of a Capillary Radiant Heating Based Typical Rural Residential Building Adopting Intermittent and Local Heating Strategy

For a capillary radiant heating based typical rural residential building adopting intermittent and local heating strategy in Beijing,the indoor thermal environment and building energy consumption were studied by using TRNSYS.The results show that when using capillary radiation heating,the room temperature changed quickly after stopping heating and reheating.On the coldest day,when the intermittent and local heating control strategy was adopted,the room temperature decreased to about 12℃after stopping heating.According to the room temperature statistics of the whole year,when the intermittent and local heating strategy was used,the percentage of time in which the room temperature reaching the design standard could be maintained at over 90%,and the total energy consumption of the building could be reduced by about 8.83%.
