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。
Refrigeration performance test of 35 multi-line machines was carried out on a multi-line machine, and the full-line cooling performance of the multi-line machine was obtained. Applying the building cooling load model, the cooling running time model and the measured multi-line performance values specified in GB / T 17758-2010 “Unitary Air Conditioner”, three current evaluation systems of China, Japan, Cooling season operating performance is calculated and compared with the performance of the seasonal conditions of the whole working conditions are compared, pointing out the differences between the evaluation indicators.
