Refrigerators are one of the most frequently used household devices; therefore, they represent an interesting subject for investigations. One of these research topics is the condensation problem in the gasket region. Despite the use of heaters in the refrigerator door, condensation on the surface of the gasket may still occur. Thus, there is a need for an improved gasket structure to overcome the condensation on the surface of the gasket. The present study aims at development of a new gasket design to prevent condensation in its region of the refrigerator. Critical points, where condensation may occur on the gasket surface, were determined experimentally and the parameters of a new design were clarified by numerical analysis. Various air chambers were created in the gasket to change the temperature distribution on the surface for preventing condensation at some critical points. The effect of these air chambers' location on the temperature distribution in the gasket region was investigated and the temperature of the potential condensation zones was relatively increased.

防止冷凝的冰箱门垫片的设计与开发

冰箱是最常用的家用设备之一。因此，它们代表了一个有趣的研究主题。这些研究主题之一是垫圈区域中的冷凝问题。尽管在冰箱门中使用了加热器，但垫圈表面仍可能发生冷凝。因此，需要一种改进的垫片结构以克服垫片表面上的冷凝。本研究旨在开发一种新的垫圈设计，以防止在冰箱区域内发生冷凝。通过实验确定了在垫圈表面可能发生冷凝的临界点，并通过数值分析阐明了新设计的参数。垫圈中形成了多个气室，以改变表面上的温度分布，以防止某些关键点发生冷凝。研究了这些气室的位置对垫片区域中温度分布的影响，并潜在地增加了冷凝区域的温度。
