| Summary: | 碩士 === 華梵大學 === 機電工程研究所 === 94 === The objective of this research is to understand the temperature and flow fields of the interior of a refrigerator. Computational fluid dynamics based on the finite volume method is employed to investigate the flow and temperature fields. The simulated model includes the freezer compartment, fresh food compartment, separating plates, and flow passages. For the fluid domain, equations of conservation of mass, momentum, and energy are solved to obtain the temperature, pressure and velocity distributions. Conjugate heat transfer is utilized to comprehend the thermal fields of the solid domain. Thus temperature distributions of solid segments are also computed. The parameters, which are detrimental to the overall heat transfer efficiency, such as flow passage design are investigated. The ultimate purpose of this study is to improve the efficiency of a domestic refrigerator through optimal interior and flow passage design.
