| 为了设计应用于闭式河水源热泵系统的螺旋管换热器，采用数学模型和经验公式对闭式河水源热泵系统的螺旋管换热器的换热面积进行了理论
计算，进而设计了螺旋管换热器的结构。根据上海松江地区的河水温度情况，通过试验研究了不同冷却水流量对螺旋管性能的影响。实验结果表明：此闭式河水
源热泵系统螺旋管换热器的换热量为10.76 kW，单位管长的换热量为27 W/m。实验方法得到的换热量与理论方法得到的换热量之间的误差为3.5%，说明设计螺旋
管换热器的理论计算方法是可信的。 |

| In order to design a helical coil heat exchanger (HCHE) which can be used in the closed loop river source heat pump system(RSHP), the heat
transfer area of the HCHE of the RSHP was calculated theoretically with the mathematics model and the empirical formula, and then the structure of the HCHE was designed. Meanwhile,
according to the condition of the river temperature in Songjiang area of Shanghai, the influence of different cooling water flow on the performance of the spiral coil heat exchanger was
studied. The experimental results showed that the heat transfer of HCHE of the RSHP is 10.76kW and the per meter heat transfer was 27W/m. The error between the heat transfer obtained
by the experimental method and the heat transfer obtained by the theoretical method is 3.5%, which shows that the theoretical calculation method of HCHE is credible. |
