The effect on the long term heat storage for heating and cooling in consideration of the thermal energy cycle between heating and cooling has been evaluated from the experimental and analytical points of view.Two kinds of experiments for ground source heat pumps (G.H.P.) with burried vertical pipes and horizontal pipes have been conducted. It is found that the ground source heat pumps (G.H.P.) are effective to energy conservation and long term heat storage for domestic heating.As for vertical type G.H.P., the double U type tubes is beneficial and have large amount of heat storage and extraction rates through the soil. The cold thermal energy stored in the soil during winter by G.H.P.can be used as a heat source to cool rooms efficiently in summer.As for G.H.P.with horizontal tubes, it has good efficiency of heat extracting rate compared with vertical tubes. The theoretical analysis is proposed to solve the interfering heat transfer with the vertical multi-tube systems using convolution law of line source theory. We can get the reasonable heat storage rate and energy saving of any kinds of configuration.

本文从实验和分析的角度评价了考虑制热与制冷之间的热能循环对长期制热和制冷蓄热的影响。采用埋地垂直管和水平管的方法进行了试验。研究发现，地源热泵（G.H.P.）对家庭供暖节能和长期蓄热是有效的。对于立式G.H.P.，双U型管是有益的，并且具有通过土壤的大量热存储和提取率。地源热泵冬季储存在土壤中的冷热能可作为夏季室内降温的有效热源，水平管地源热泵与垂直管地源热泵相比，具有较好的取热效率。利用线源理论中的褶积定律，对垂直多管系统的干扰传热问题进行了理论分析。可以得到各种结构的合理蓄热率和节能量。
