Abstract

In order to improve the utilization of solar energy and to reduce the energy consumption of an auxiliary heat source, this study investigates a phase change heat storage device for an LPG vaporization system utilizing solar assisted heat pump (DX-SAHPV). In this study, paraffin was chosen as the phase change material (PCM). The structure of phase change heat storage device was determined by the simulation using the Fluent software. The optimal radius of each PCM sphere is 60 mm. The phase change rates and corresponding temperature distributions were also analyzed during the thermal storage process and the release process, respectively. Finally, an economic analysis was made to investigate the optimal heat storage capacity of the PCM device.
