Abstract: In view of characteristics of working medium and villages buildings, the paper took pebble as material to store collected solar energy and studied the regenerator performance by numerical simulation (Matlab Programming) and experimental research. To comprehensively consider heat-exchange performance and operating cost, average regenerative power and air flow resistance were taken as target functions. Research results showed that the larger cross section velocity and length of pebble bed, the larger average heat storage power and air flow resistance. However, it''s different for pebble diameter. The smaller pebble diameter, the larger average heat storage power and air flow resistance. So, pebble diameter was suggested to be 0.04∼0.08m. The determination of cross section velocity and length of pebble bed would need to take into account volume flow and regenerator structure. [Copyright &y& Elsevier]
