摘要
建立了相变蓄热球体堆积床热性能的传热模型,应用焓法计算了蓄热体内部的相变过程,得到了蓄热体在同一点各时刻及同一时刻各点的蓄热与放热性能曲线图,分析了多种因素对蓄热放热性能的影响,为相变蓄热球体堆积床的性能分析提供了理论指导,为其在空调中的应用奠定了基础.
Simple model was develped for analyzing the thermal performance of thermal energy storage systems using phase change material capsules. Adopts enthaply method to simulated calculation of one-dimensional the phase change process in the heat storge units region,get the chart of the heat stored and releasing performance of the one dimensional model with phase change material capsules and the curve of the temperature changing of phase change material in difference place. It can be uesd for designing and analyzing the thermal performance of thermal energy storage systems using phase change material capsules, which lays the foundation of the applicating in the air-conditioning.
