浅埋竖管换热器地热源热泵夏季供冷试验研究

Experiment of cooling by the ground source heat pump with shallow buried vertical tube exchangers

介绍了根据浅埋竖管换热器地热源热泵冬季测试结果 ,在夏季试验中对试验装置及实验方法的改进 ,测试了夏季定水量 ( 63天 )的运行效果和变水量运行时各性能指标的变化。采用系统能量平衡结合热传导方程建立的地下竖埋套管管群换热器传热模型和过渡季大地温度场模拟 。

Describes the improvements on the experiment procedure and instrumentation based on the measurement results in the winter heating mode, presents the measured effects of system operation under constant water volume conditions and variation of the parameters with variable water volume. Derives a heat transfer model for buried vertical tube heat exchangers and simulation of the ground temperature field from energy balance and the thermal conduction equations, which is consistent with measured results.
