We present the overall results and analysis of a long term rock-bed thermal storage experiment carried out at the C.S.T.B. Centre of Sophia Antipolis (Valbonne), in collaboration with CNRS (Orsay). The pebbles tank (160 m 3) was excavated directly in the earth and insulated ; there were two means to blow and extract air in/from the pebbles tank : either through an air loop where air could be preheated, or from a field of air solar collectors. This installation allowed various sets of thermal charges and discharges, separated by relaxation periods. The thermal measurements during these relaxation periods were analysed by comparison with a numerical model ; this analysis exhibit clearly the thermal losses of the storage system towards the sur...
