Abstract/Summary Ice slurry, a biphasic refrigerant, has been instated as one of the potential candidates due to its high heat transfer capability as a phase change material. Previous research show that ice slurry flows contribute to reductions in the amount of charge of primary refrigerant and enables load shifting which results in substantial operating cost savings. In this study, a numerical analysis of a heatexchanger performance operated with ice slurry is presented. The role of variousparameters including ice concentration and mass flow rate on the heat transfer and pumping power is presented and results are compared with those for the carrier fluid at the same conditions. The results show that ice slurry and geometry of the heat exchanger enhance the heat transfer performance. A significant increase in the pressure drop is also observed for the ice slurry flowing through this type of heat exchanger.
