摘　　要：介绍了既有建筑空调系统节能改造的流程。针对空调系统能耗调研一般只在短期内进行,长期测试难以实现的情况,提出了在进行能耗分析时,合理利用短期内的测试数据与当地室外气象参数,通过拟合计算出空调系统的供冷、供暖负荷,为节能改造提供评价依据。结合工程实例,对该方法的实际应用进行了探讨。The process of energy-saving reconstruction of existing buildings is introduced. The in- vestigation on energy consumption of air-conditioning system is generally conducted in a short term, while the long term test is difficult to achieve. When the energy consumption analysis is conducted, the cooling or heating load can be calculated by fitting the short-term test data of air-conditioning system with the lo- cal outdoor meteorological parameters rationally. The findings can provide the evaluation basis for energysaving reconstruction. The practical application of the method is discussed with a project example.
