摘　　要：正确估算的年运行费用是供热空调系统方案确定的关键参考因素之一。本文分析了负荷与费用之间的关系,根据各种负荷的成因、特点及影响因素进行分类,在标准的平均面积负荷指标基础上考虑各种因素修正,给出了一种新的年费用估算方法,指出降低费用的关键在于提高能源利用效率和降低燃料成本单价。实例计算结果说明该方法具有较好的准确度。Correct operating cost estimation is one of the critical factors to determine heating and air- conditioning system program. Because load is the base of expense calculation, the cause, feature and influencing factors of different load were analyzed and classified. A new estimation method of annual cost was given, which was on the basis of standard mean area load index and varied correction factors. Improving energy efficiency and reducing fuel price are the route to decrease operating cost. An example calculation proved that this method presents better accuracy.
