Description
The regenerator is a vital component within the liquid air energy storage system, enabling the transfer of cold energy between the processes of air liquefaction and gasification. Solid-phase cold storage, distinguished by its lack of operating temperature constraints, environmental friendliness, and cost-effectiveness, stands out as a highly promising method for cold storage in liquid air energy storage systems. The solid-phase regenerator undergoes periodic cycles of heating and cooling during the processes of air liquefaction and gasification. To explore the dynamic temperature variations in the external insulation material of the solid-phase regenerator and improve the insulation performance of the solid-phase cold storage tank, this study developed a dynamic computational model for the tank's insulation system. It simulated the temperature distribution and dynamic changes of the insulation material in both the first-stage (173~300 K) and second-stage (98~175 K) cold storage tanks under periodic temperature fluctuations within the tanks. The dynamic temperature changes of the insulation material were examined with a focus on the effects of insulation material type, thickness, and the rate of temperature increase and decrease inside the storage tank.
