The Uncertainty Analyse Of Test Of Compressors

As the core of the air-condition, the quality of the refrigerant compressor infects the refrigeration effect of the refrigerant system directly. For the true value, the test of compressor is especially important. But there are some problems about the uncertainty of compressor test. Besides lacking enough normative consciousness of uncertainty, there are too many factors infecting the refrigerant output and the relations are complicated. It is difficulty to make the transfer relations between the factors and the refrigerant output clear. In addition, it is difficulty to reflect the effect of the material property. And the huge calculation due to the complex transfer relation is a barrier now. All of the above factors are preventing from erecting the uncertainty calculation model to obtain the uncertainty. In order to solve all of above problem, this paper includes these following aspects.Make the factors effecting the uncertainty sure and make the reasons leading effecting factors clear. Give out the degree of confidence, confidence interval, distribution and the function relations between the uncertainty and parameters and calculate the parameters uncertainty.Aim at all the tests, deduce the sensitivity coefficients reflecting the transfer relation by make all the factors infecting the output and erect the uncertainty model elementarily.Recurring to the compressor mathematic model, analyses the degree of work condition acting on the uncertainty and consummate the uncertainty model farther by calculating.Conclude an integrated evaluation method of refrigerant output uncertainty of compressor and value all the nine tests based the uncertainty.According to the model of uncertainty of compressor test, make software with VB.Provide the optimization project for compressor's test system.
