摘要(Abstract):
从传热和能量平衡的角度建立了竖直盘管式直接蒸发冰蓄冷空调系统的数学模型,对其蓄冰机理进行了理论分析,得到了结冰过程的传热特性和结冰动态特性。并且利用实验数据验证了数值计算模型的合理性和准确性。结论可用于指导直接蒸发冰蓄冷系统的设计和开发。
The mathematical model for direct evaporation ice-on-coil thermal storage system was developed based on the heat transfer and energy conservation.The heat transfer coefficient and its dynamic characteristics during the chaging process were numerically analyzed.The simulation results showed a good agreement with experimental data with a real ice-on-coil system developed by our laboratory.
