【Abstract】 The steady heat transfer model for the U-pipe pile heat exchanger in the soil was established using the method of the energy conservation. The thermal characteristic of the U-pipe pile heat exchanger versus the thermal interference of pipe legs and thermal properties of soil based upon the application of the ground source heat pump engineering in Tianjin was calculated更多还原
