建筑能源审计中冷水机组现场能耗评估方法

Energy consumption field assessment method for water chillers in building energy audit

在建筑能源审计中,冷水机组的现场测试及能耗评估对分析空调系统的能耗以至于整个建筑的能耗起着至关重要的作用。利用编制的能耗评估软件,得出实际运行工况下冷水机组的理论推算性能系数,将实测的性能系数与其进行比较,从而判断冷水机组的运行效率是否合理,能耗是否正常。针对两幢建筑物的工程实例,通过现场测试并进行能耗评估分析,验证了该冷水机组现场能耗评估软件的可靠性。

Field testing and energy consumption assessment ot water chillers play an important role in analyzing energy consumption of air conditioning systems and the whole building in building energy audit. By the energy consumption assessment software worked out by the author, theoretical calculation COP of water chillers in actual conditions is obtained and compared with the measured COP to determine whether the operating efficiency of water chillers is rational＇and energy consumption is within a normal range. With two building project examples, through the field testing and the energy consumption assessment, proves that the energy consumption assessment software is reliable.
