Research on Evaluation Indicators of Integrated Energy Storage Water Tanks for Heat and Cold Storage
摘要
Abstract
The working principle of integrated energy storage water tanks for heat and cold storage is elaborated,and the design feature numbers and evalua-tion indicators are analyzed.The Froude number Fr and Reynolds number Re are analyzed,and it is pointed out that the principle of Fr less than or equal to 1 should be followed in the design of water distributors.The concept of velocity uniformity coefficient is pro-posed to evaluate the velocity uniformity of the horizon-tal section of energy storage water tanks.The thickness of thermocline,half-cycle performance coefficient and exergy efficiency are analyzed to quantitatively analyze the stratification effect and energy storage efficiency of energy storage water tanks,providing an evaluation ba-sis for the design and optimization operation of energy storage water tanks.关键词
