A theory is presented for modeling rotary heat and mass exchangers with infinite transfer coefficients. The continuity and energy conservation equations for one-dimensional transient flow are established and analyzed. Solutions to the equations are obtained by the method of characteristics and the shock wave method. Both methods provide a set of analytical equations that allow performance prediction of the heat and mass exchanger with infinite transfer coefficients for any inlet and operating conditions. A regenerator-operating chart is introduced which shows the fundamental modes of operation for rotary heat and mass exchangers. Part II presents correlations for the effectiveness of rotary dehumidifiers with finite transfer coefficients.
