Evaluation model of refrigerator cooling performance

In order to comprehensively and quantitatively evaluate the cooling performance of the refrigerator, a model for evaluating refrigerator cooling performance was designed. The model selected several key parameters of the refrigerator cooling process as the evaluation index, and assigned its set value, base deviation and weight coefficient, calculated the deviation proportion of each evaluation index, and its individual scores, finally got a percentage score that reflect the refrigerator cooling performance with summing the weighted scores. Application results showed that the model can comprehensively and quantitatively evaluates the refrigerator cooling performance and the differences between each other's, by calculating the data collected form the cooling process with the same evaluation scale and testing error.
