摘　　要：为了提升末端空调机组换热器在高进出水温度(进水温度10℃,出水温度17℃)下的换热能力,以某一深圳地铁站为例,针对一种高效双级换热器的换热性能展开研究,并基于实验数据,建立双级叉排换热器设计模型,利用CFD技术进行换热器内部流场模拟分析。结果表明,本高效双级换热器设计在高进水温度和大进水水温差下,提升了换热能力,保证了表冷盘管的除湿能力。In order to improve the heat exchange capacity of the heat exchanger of the terminal air conditioning unit under high inlet and outlet water temperature(inlet temperature 10℃,outlet temperature 17℃),the heat exchange performance of an efficient two-stage heat exchanger was studied in a Shenzhen subway station.Based on the experimental data,the design model of the two-stage cross-row heat exchanger was established.CFD technology is used to simulate the flow field inside the heat exchanger.The results show that the design of the high-efficiency two-stage heat exchanger improves the heat transfer capacity,ensures the dehumidification capacity of the surface cold coil.
