摘　　要：对竖直盘管直接蒸发蓄冰空调系统的蓄冰槽进行了蓄冰和融冰过程的传热试验和数值模拟研究,获得了蓄冰过程中水温变化、水温分层、以及融冰过程中制冷剂过冷温差及水温的升高规律。采用分布参数的方法建立了数学模型,对直接蒸发蓄冰槽进行了详细的数值模拟研究,计算结果与试验数据能够较好的吻合。由此为直接蒸发内融冰式冰蓄冷空调产品的设计及控制过程开发提供了基础数据。The heat transfer characteristics of the direct evaporation thermal storage air conditioning system with vertical coils is investigated during the charging and discharging process with experiments and numerical simulation. The distribution of the water temperature along the tank height, together with the variation of this temperature during the charging and discharging process are tested. The super cold temperature difference of the refrigerant during the discharging process is also obtained. The mathematic model was developed and the simulation research was particularly illustrated. The simulation results agree with the experimental data well. This study can provide experimental data and theoretical foundation for the design of the direct evaporation ice storage air conditioning system.
