摘要
通过试验和模拟分析 ,研究了地源热泵 ( GSHP)地能利用中 ,间歇控制过程对系统输出性能的影响、对井壁附近温度恢复的影响以及井的结构参数对系统输出性能的影响。试验和模拟计算结果表明 ,间歇控制技术能使井壁附近温度得到有效恢复 ,对发展利用地能供热供冷系统具有非常重要的实用价值。
Based on experimental research and numerical simulation, the effect of the intermittent operation of GSHP (ground source heat pump) on the system output was studied. The effect of the intermittent process to the restoration of ground temperature around the bore and the effect of the structural parameters of the bore to the output were also investigated. Experimental and simulation results indicate that the intermittent process can help the effective restoration of the ground temperature around the bore. The technique is of great importance to the promotion of the GSHP in HVAC in the future.
