Thermal storage characteristics of solar-ground source heat pump system
摘要：
结合工程实例，对太阳能-地源热泵联合运行系统进行了3种工况的地下蓄热特性测试。对蓄热功率的计算结果表明，太阳能-地源热泵联合系统地下蓄热功率最大值可达203.3 kW，平均值达69.09 kW，相对于地源热泵单独蓄热功率提高了90%以上，增加了地下蓄热量，提高了地层温度，有利于东北严寒地区地源热泵冬季供暖的高效、稳定运行。
Abstract：
According to a practical project, tests the thermal storage characteristics of the solar-ground source heat pump system in three different conditions. The calculation results show that the thermal storage power of the combined system can reach the maximum value of 203.3 kW and the average value of 69.09 kW, which is 90% higher than that of single heat pump. The combined system significantly increases the underground thermal storage capacity, improves the stratum temperature, and is helpful to high efficient and stable operation of ground-source heat pump system in the northeast cold region.
