摘要
针对青岛地区的气象与地质条件,以土壤温度恢复率为指标,对太阳能-土壤源热泵系统(SESHPS)的交替运行性能进行了数值模拟.结果表明:SESHPS以24 h为周期交替运行时,近盘管处土壤温度恢复率取30%~60%为宜,太阳能热泵投入运行的时间比例应控制在42%~58%,以此可确定出太阳能集热器的面积,为SESHPS的实际工程设计与运行提供了理论参考.
Based on the climate and soil condition of Qingdao, the performance of alternative SESHPS (solar-earth source heat pump system) was numerically simulated according to the soil temperature resuming-rate. Result indicates that the soil temperature resuming-rate of 30% ~60% near the buried coil is preferable when SESHPS operate alternately by a period of 24 hours, and the time of SAHP(solar assisted heat pump) operation should be confined to 42% ~58%. Based on this result, the area of solar-collector can be calculated. This may provide some references for practical engineering design and operation of SESHPS.
