비정상상태 해석을 이용한 냉각 사이클 내 냉매 분포도 및 성능 분석 = A transient numerical study on refrigerant distribution and performance of a refrigeration cycle

다국어 초록 (Multilingual Abstract)

This study aims to develop a transient numerical model for predicting the refrigerant charge distribution and performance of a refrigeration system. A vapor compression system using R600a is analyzed at the start up condition. With system initialization, condenser experiences increase in inlet refrigerant quality and increase in total refrigerant charge, due to the influence of high temperature refrigerant discharged from the compressor. The effect of the refrigerant property at the upstream control volume is seen to properly propagate in the direction of the fluid flow. As the compressor RPM increases, the mass flow rate of the system increases, and the cooling capacity consequently increases.
