摘　　要：相变储能材料与空气源热泵的耦合应用可有效提高空气源热泵的效能,促进能源的优化配置。本文提出了一种与空气源热泵耦合的双向相变储能系统,并进行了储能材料的测试和系统储能单元的模拟分析。首先,提出了储能系统的制作方案及其与空调水系统的连接方式。而后,采用步冷曲线法研究了不同组分的十二醇与癸酸的二元混合物相变温度,得到了相变蓄冷材料中十二醇与癸酸的比例;利用DSC对石蜡进行测试,选定46#石蜡作为系统的相变蓄热材料;利用Fluent软件对相变储能单元进行模拟,得到了最佳板厚。Coupling application of phase change materials and air-source heat pumps can effectively increase the efficiency coefficient of air-source heat pumps, so as to achieve more rational utilization of resources. In this paper, a two-way phase change energy storage system coupled with air-source heat pumps was brought forward, and performance tests for energy storage materials and simulation analysis for energy storage units were carried out. Firstly, the manufacturing plan of energy storage system and connection modes with air-conditioning water system was presented. And then, phase-transition temperature of binary mixture composed of lauryl alcohol with different components of eapric acid was researched through cooling curves,thus the ratio of lauryl alcohol and capric acid in phase-change cold storage materials was acquired. In addition,paraffin was tested through DSC,and 46# paraffin was finally selected as the phase-change heat storage material of this system. Lastly,phase change energy storage unit was simulated through Fluent Software to acquire the optimal board thickness.
