| Abstract: | Small vapor compression refrigeration systems incorporate a non-adiabatic capillary tube called a capillary tube-suction line
heat exchanger (SLHX) in order to improve performance. The thermodynamic properties of the refrigerant in the capillary tube
and suction pipe are influenced by associated phenomena. This study compares various relevant models. Based on the comparison
recommended correlations were selected and the simulation results show that the friction factor model has the most dominant. |
