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.
