Résumé

Solar energy is an important environment-friendly energy. The paper introduces the concept, classification, and development of central solar heating plants. A seasonal solar energy application must be incorporated with heat storage to bridge the gap between demand and supply of heat and achieve a high solar fraction at a reasonable cost. An interesting solution to the storage problem is seasonal storage in clay. The paper presents theoretical analysis about heat transfer process during charge process of first cycle in duct heat store. A finite line source model is presented to analyze the process when influence radius is within thermal insulation. It is concluded that proper thermal insulation areas upper boreholes and the dimension with long diameter and short depth of boreholes are suitable for duct heat store.
