Energy storage performance of a rectangle phase-change-material heat-exchanger

Presents the structure of a rectangle phase-change-material heat-exchanger (PCM-HE). Establishes a mathematical model for PCM-HE during energy storage based on the enthalpy method. Studies the energy storage performance of PCM-HE with the phase change material of CaC_l2·6H₂Oand the variation of refrigerant temperature. The results show that the phase change material can finish its phase change in 58 min; the rate and amount of energy storage are 107.5 W and 484.2 kJ respectively.
