摘　　要：由于室外环境条件无法控制,使得实际运行环境下的多联机性能评价存在困难.针对该问题,本文参考多联机产品性能评价指标制冷季节能效比/制热季节能效比/全年性能系数,提出6点测试法用于评价实际运行环境下的多联机性能.以办公建筑中实际运行的1套多联机为例验证本文提出的多联机性能评价方法.经测试计算,发现实际运行环境下的多联机制冷季节能效比测量值与标准计算值之间的偏差小于10%.研究结果表明,该评价方法可以用于评估多联机设计与实际运行之间的性能差异,也可以用于不同多联机之间的性能对比分析,具有较好的工程实用价值.It is difficult to evaluate the performance of multi-connected air-conditioning(heat pump)unit under field operation because of the uncontrol of outdoor environmental conditions.In order to overcome this issue,referring to the evaluation indicators for the performance of multiconnected air-conditioning(heat pump)unit products,including SEER,HSPFand APF,one new six-point testing method is put forward to evaluate the performance of multi-connected airconditioning(heat pump)unit under field operation.Taking a set of multi-connected air-conditioning(heat pump)unit under field operation in an office building to validate the proposed performance evaluation method.After the testing and calculation,it’s found that the deviation between the test value and the standard calculation value of SEERf(seasonal energy efficiency ratio in field operation)for the multi-connected air-conditioning(heat pump)unit is less than 10%.The research results show that the evaluation method can be used to evaluate the performance difference between design and field operation,and the comparison among different multiconnected air-conditioning(heat pump)units in field,which has good value for engineering practice.
