| Abstract: | Based on the line-source theory, combined the concept of resistance, a physical model of vertical U-tube coil for ground source heat pump system was introduced, and the main parameters influencing the heat-exchange effect for this system were calculated. Compared the calculated results with the experimental values, the error can be neglected for engineering applications. The quantity of heat exchange for unit well depth and the needed horizontal spacing can be obtained under different buried tube forms by t... |
