Summary

Rotary regenerative heat and mass exchangers (enthalpy exchangers) can reduce air-conditioning costs in ventilated buildings by recovering energy from the exhaust air and transferring it to the supply air stream. In the study the adsorption isotherms of a desiccant used in a commercially available heat and mass exchanger were measured. The isotherms and other property data were incorporated into the program MOSHMX, which numerically solves the governing equations for combined heat and mass transfer. The numerical results were then used to develop a computationally simple model for determining the performance of a specific enthalpy exchanger as a function of the air inlet conditions and the matrix rotation speed. The enthalpy exchanger model was used in the transient simulation program TRNSYS to estimate the annual performance.
