Abstract

Refrigerators are comprised of compressors, condensers, expansion valves, and evaporators. Among these parts, a compressor accounts for the majority of power consumed by a refrigerator. Therefore, it is important to improve the efficiency of a compressor to save the electrical energy consumed in a household. In this study, the variation in energy efficiency ratio (EER) with respect to muffler shape was examined for a linear compressor suction system. Furthermore, two cases, namely the baseline model and modified model, were considered. For numerical analysis, a one-dimensional lumped model and CFD coupled model were adopted. The numerical analysis results indicated that the modified model improved EER by approximately 0.49% in comparison with the baseline model. Hence, the modified model was more effective in energy saving. Additionally, the experimental results were qualitatively consistent with the numerical analysis results.

Keywords:

Linear compressor, Suction system, 1D lumped model, 2D CFD model, EER (Energy efficiency ratio)
