The present work deals with vapor compression cycle and methodology for simulation based model in DYMOLA. In this work, the flow through capillary is modeled using Multi-cell model concept and quality at the outlet of the capillary is analyzed for design of evaporator. The study focuses on pressure drop across capillary that affects the flow of refrigerant. The Ordinary Differential Equations are solved to capture the nature of flow. The capillary tube and suction tube in considering brazed condition is considered for modeling purpose. The validation of the developed model is performed using the p-h chart as reported in literature. The results presented in terms of effect of Degree of Subcooling on capillary length and outlet pressure. Furthermore, the study shows the behavior for various parameters such as outlet pressure, pipe thickness and length of pipe and its effect on design parameters. The results are also presented to show the effect of pressure drop in vapor compression cycle for subcooling boundary layer.
