Rotary type regenerators are used for energy recovery from waste heat, especially in low temperature applications such as air conditioning systems. In this study, the developed mathematical model for rotary type regenerators has been solved with finite difference method using two different boundary conditions and the effects of the boundary conditions on the results have been investigated. Two different boundary conditions have been used at transition points between periods. It has been shown that the assumption of there is no heat transfer in the fluid at these points yields better results rather than assigned fluid temperature as a boundary condition at the transition points from one period to the other period (from the hot period to the cold period or from the cold period to the warm period).
