【Abstract】 The temperature distribution in the refrigerator is a main index to evaluate the optimum design of frost-free refrigerators, which is closely relative to the flow field. We first used PIV technology to measure the inner flow field of the freezer chest of the frost-free refrigerator in China. Using the K-εturbulence model, we conducted the numerical simulation. Our mathematical model proposed in this paper is confirmed by our experimental results. The results of our study will be useful to the further research on optimization of the flow and temperature fields in frost-free refrigerators.更多还原
