中文摘要: 基于Dymola仿真平台,建立了跨临界CO2热泵储能系统动态模型,模拟研究了系统中储能水箱几何尺寸对其性能的影响,并与试验结果比对以保证模型的准确性。借助MATLAB优化工具箱,优化储能水箱的内部结构,优化后热分层系数提高了2.95%。在Dymola中建立优化后的热分层水箱模型,然后通过Dymola建立的热泵储能动态模型对储能水箱尺寸进行了优化,结果表明,优化后系统总性能系数提高了3.71%。
Abstract:A dynamic model of transcritical CO2 heat pump energy storage system is established on Dymola.The influence of geometry size of energy storage tank in the system is analyzed and compared with the test results to ensure the accuracy of the model.The internal structure of the energy storage tank is optimized by 2.95% with MATLAB optimization toolbox,and the thermal stratification coefficient.The optimized thermal stratified tank model is established on Dymola.The energy storage is optimized by using the heat pump energy storage dynamic model on Dymola.The results show that the total COP of the system after optimization is increased by 3.71%.
