摘要
本文以寒冷地区典型城市的近零能耗居住建筑为案例进行模拟计算与分析,研究了建筑室内人员作息、内遮阳作息及空调运行模式这三项因素对建筑供冷年耗冷量指标的影响,结果表明:相同的人员在室率但不同的逐时人员作息对该指标影响较小(与平均值最大相差2.68%);而内遮阳作息对该指标影响最大(最大为60.80%);不同空调运行模式而导致的供冷年耗冷量指标差别也很明显(最大为19.62%)。研究结果可为更合理地对近零能耗建筑年供冷耗冷量指标的评估及相关标准的修订提供了有益参考。
In the paper, the specifications on the daily schedules of personnel and inner sunshade, and the air-conditioning operation mode that affect the annual cooling demand of Nearly Zero Energy Buildings(NZEB) were analyzed and the results show that different daily schedule of personnel(with the same in-room rate) has little impact on the index of annual cooling demand(the largest deviation rate is 2.68%);the daily schedule of inner sunshade has the largest impact on the index(the largest deviation rate is 60.80%);and the air-conditioning operation mode has relatively obvious impact on the index(the largest deviation rate is 19.62%). The research provides useful reference for accurate evaluation of the annual cooling demand of a NZEB and the revision of the technical standard.
