多联机的三种制冷季节性能评价指标的差异性分析
Differences among three types of cooling seasonal performance evaluating index of multi-split air-cooled air conditioners
摘要：
对一台多联机进行了35个工况的制冷性能试验，获得了该多联机的全工况制冷运行性能。应用GB/T 17758—2010《单元式空气调节机》规定的建筑冷负荷模型、制冷运行时间模型和实测多联机性能值，分别采用中国、日本、美国三种现行评价体系对被测多联机的制冷季节运行性能进行计算，并与其全工况季节运行性能指标进行对比，指出各评价指标的差异性。

Abstract：
Obtains the cooling performances of a multi-split unit on full conditions by testing the unit on 35 cooling conditions. According to the building cooling load model, cooling operating time model provided in GB/T 17758—2010 and tested performance values, calculates the cooling seasonal performance of the unit by the three evaluating indexes regulated in standards of China, Japan and USA respectively. By comparing the calculated results with the full condition cooling performances of the unit, analyses the differences among these evaluation indexes.
