A numerical and experimental study of heat and mass transfer has been carried out for an energy recovery ventilator with a porous media heat exchanger. The energy recovery ventilator selected for this study has a rotary periodic heat exchanger that can transfer heat and moisture from one air stream to another. Such heat exchangers can be operated with high effectiveness by using a low-cost porous matrix as the heat exchanger medium. The influence of porosity in the matrix has been studied numerically and the performance of the energy recovery ventilator in recovering both heat and moisture has been modeled.
