Partial Cycling of Stratified Cool Thermal Storage Systems
分层蓄冷系统的部分循环
该ASHRAE研究项目研究了大型分层蓄冷系统实验室规模模型的充放电。实验室实验使用了热分层系统和盐度分层系统,其功能类似于热系统的传质。以体积流量和梯度层的初始位置为主要控制变量,进行了超过74个单独的实验。初始梯度层位置的变化对应于部分循环条件。在每个充放电过程中,在多个位置收集固定点数据,采样频率高于局部对流和浮力运动。
作为数据分析的一部分,考虑剖面边缘平移和积分厚度参数,以量化梯度层的演变。主要研究者:Kelly O. Homan,密苏里堪萨斯大学博士,RoLaCultudio: 1999年11月,一月,2002年主办:TC 6.9,蓄热
This ASHRAE Research Project examined the charging and discharging of a laboratory-scale model for large-scale stratified cool thermal storage systems. The laboratory experiments utilized a thermally stratified system as well as a salinity-stratified system, which functions as a mass transfer analog to the thermal system. Over 74 individual experiments were conducted with primary control variables taken as the bulk flow rate and the initial position of the gradient layer. Variation of the initial gradient layer position corresponds to partial cycling conditions. Fixed point data was collected at multiple locations during each of the charging and discharging processes with a sampling frequency above that of the local convective and buoyant motion. As part of the data analysis, consideration of profile edge translation and an integral thickness parameter were introduced to quantify gradient layer evolution.Principal Investigator:Kelly O.
