Dynamic thermal loss of ice tank of seasonal ice storage for air conditioning

With societal advancement and improving living standards, developing sustainable and cost-effective cooling systems has emerged as a pressing priority. As a result, this paper proposes an outside air inter-seasonal cooling storage system. The dynamic cold transfer model between the cold storage reservoir and the soil is established. This study analyzes the effects of cold storage reservoir geometry (shape and size) and insulation layer thickness on the dynamic thermal losses of the system. The results show that the thickness of the cold insulation layer is negatively correlated with both the amount of cold loss capacity and the cold loss rate. The cost of the dynamic cold loss process is always lower than that of the steady state. The volume-to-area ratio exhibits a negative correlation with both the cold loss rate and the annual cost per unit area. The minimum values for cold loss capacity and cold loss rate occur when the cylindrical storage tank's height-to-diameter ratio equals 1. When the volume of the cold storage reservoir is 400 m3, the impact of the variation in the ratio of cold price and cold insulation layer price is consistent. This system can be applied to meet people's cooling needs in practical applications.
