Experiments and a One dimensional Heat Transfer Model of Ice Making to Store Coldness by a Pipe Utilizing Natural Cold Resource

通过对利用自然冷源单管制冰过程的传热分析，建立了管制冰的一维传热模型，在蓄冰池围护为绝热条件下，用积分法对一维模型进行了求解；在模拟自然冷源制冰实验台进行的单管制冰试验表明：管道制冰半径与制冰时间呈幂函数关系，一维传热模型解析解的计算结果是可靠的。

Based on the analyzing and studying one pipe freezing ice process utilizing natural coldness resource (NCR),the one dimensional heat transfer model is developed and solved using integral method. Experiments is peformed for ice making utilizing NCR by one pipe The results show that the radius of ice block is the power function of ice making time and the integral solution of the one dimensional heat transfer model is reliable.
