许多研究者分别提出了不同的表征储热水箱分层性能的指标,本文对这些指标进行了归类和综述,较详细地解释了出水效率、?效率、混合数、取出效率、斜温层厚度、理查森数、高径比、分层数等指标的定义、计算方法及各自的特点。出水效率越高、取出效率越高、理查森数越大、混合数越小、斜温层厚度越小,水箱分层效果越好;高径比介于3-4对于水箱分层是比较合理的值。本文为选用合适参数对水箱性能进行研究提供了参考和借鉴。
Many researchers put forward different indexes to characterize the stratification performance of hot water storage tanks respectively. In this paper, these indicators are classified and reviewed, and the effluent efficiency, efficiency, mixing number, extraction efficiency, Thickness, Richardson number, height-diameter ratio, the number of layers and other indicators of the definition, calculation methods and their own characteristics. The higher the effluent efficiency, the higher the removal efficiency, the greater the Richardson number, the smaller the number of mixing, the smaller the temperature of the stratosphere, the better the effect of the stratification of the tank; height to diameter ratio between 3-4 for the stratification of the tank is more reasonable value. This article provides a reference and reference for choosing proper parameters to study the performance of water tank.
