摘要
水蓄冷系统作为一项平衡电力负荷、缓解用电紧张的有效措施,正在得到越来越多的重视和应用。叙述了温度自然分层型蓄冷槽内布水器的工作原理、分析了斜温层对制冷工况的影响,利用CFD软件,建立了蓄冷槽的计算模型及边界条件,同样对蓄冷和放冷的非稳态过程进行了数值模拟,对槽内的温度场及速度场进行了分析,并且基于分析结果,确认了影响斜温层厚度的主要因素。
Chilled water storage as one of the effective measures in balancing electrical power load and Overcome summer electrical shortage,it receives more and more recognition and application. This paper describes the working principle of cool storage groove of the temperature natural layered, and analyzes the thermocline effect on refrigeration condition. By CFD software, cool storage groove calculation model and boundary conditions was established,as well, completed the unsteady prosess numerical simulation of cool storage and cool release. And on groove temperature field and velocity field were analyzed. Based on the analysis results, geted the influense ofthermocline thickness major factor.
