| Abstract: | Develops the heat transfer model.Tests the heat transfer characteristics of the coils in different conditions and analyses influences of the flow velocity inside and outside the tube,tube diameter and cooling/heating conditions on the heat transfer performance of the coils.Also analyses the relation between the heat exchange rate and the coil length,and gives the curve chart reflecting the relation between the heat transfer rate and the coil length under different approach temperature differences. |

| Keywords: | surface water heat transfer coil heat transfer characteristics flow velocity approach temperature difference coil length |
