A theoretical approach to the optimum volume of rock bed and its charged thermal energy for ah air-based solar heating system in charging mode is presented. The following results are obtained : (1) As a result of system simulations, the charged thermal energy increases generally along with the increasing of rock bed volume, and the charged thermal energy has an upper limit corresponding to air flow rate. The minimum volume of roch bed which can be charged until almost upper limit is regarded as the optimum volume. (2) The relationship between the optimum volume of rock bed and the air flow rate is approximately obtained as a solution of simultaneous equations for two models on the assumption of infinite flow rate or infinite rock bed volume, and this numerical solution is found to be linear approximately. It is found that the linear approximation model derived from these two models agrees well with the solution of simultaneous equations.
