Parametric evaluation of governing heat and mass transfer resistance in membrane based heat and moisture exchangers.

Number: pap. 2125

Author(s) : ARMATIS P. D., FRONK B. M.

Summary

A heat and mass transfer resistance and pressure drop model is developed and implemented to evaluate the sensible and latent effectiveness of a counter-flow membrane based heat and moisture exchanger. The performance of pin-fin and bare high aspect ratio rectangular channel architectures are compared. Dominant heat and mass transfer resistances are also investigated. It was shown that the heat transfer is dominated by the convective resistance while the dominant mass transfer resistance shifted to the membrane at smaller hydraulic diameters. The results suggest that as membrane technology improves, enhancements to the air-side heat and mass transfer coefficients will be required to continue to realize performance gains.
