ABSTRACT -- CTS-9321918 Bejan The proposed research focuses on the determination of the optimal on/off sequence for defrosting refrigerators, in an effort to minimize the power requirement. The results will include the optimal time intervals of continuous operation and defrosting, and the optimal way to divide a fixed amount of heat exchanger area between the evaporator and the condenser. It is also proposed to optimize the ice making process by optimally selecting the on/off sequence of operation, i.e., the time intervals for freezing and ice removal. Two manufacturing methods will be optimized, ice on tube and ice in tube. The work will be performed analytically, numerically, and experimentally.

摘要/ ABSTRACT摘要：本研究的重点是确定除霜冰箱的最佳开/关顺序，以尽量减少电力需求。结果将包括连续运行和除霜的最佳时间间隔，以及在蒸发器和冷凝器之间划分固定数量的换热器面积的最佳方法。还提出了通过优化选择操作的开/关顺序（即冻结和除冰的时间间隔）来优化制冰过程。将优化管上冰和管内冰两种制造方法。这项工作将以分析、数值和实验的方式进行。
