Based on the steady state distributed parameters model of the condensers which was put forward in the previous related reference. The effect of different non-uniform air distribution,different flow rate of the refrigerant,different refrigerant layout and different rows on the performance of the condensers are studied and some useful results are obtained. All the non-uniform air distribution make the performance of the condensers worse. The non-uniform degree can be measured by the non-uniform factor. When the non-uniform factor increase,the performance of the condensers become worse. All these research results can be applied to predict the influence on the performance of condensers when the inlet air distribution is non-uniform.
