Performance enhancement of ice storage units for the storage of grain in low temperature
The use of ice storage devices is a crucial technology for energy conservation and e-mission reduction,as it allows for the storage of surplus electricity into cooling energy during off-peak periods and the release of stored cooling energy during peak periods.This paper focuses on the performance of a finned tube ice storage unit using numerical simulations based on the en-thalpy-porosity method.The typical ice storage process is analyzed and the underlying heat transfer mechanisms is investigated.Furthermore,the influences of fin parameters including thickness,height,and number on the performance of the ice storage unit are quantitatively as-sessed.This study is beneficial for the design of the finned tube ice storage device for further ap-plications in grain storage under low temperature.
