Research on Performance Design and Test of High Efficiency Heat Exchanger
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.
