Membrane-based energy recovery ventilators (ERV) are an effective means of reducing energy cost and allow for scaling down HVAC equipment. Owing to their compact geometry and rough surfaces of the porous membrane substrate, ERV exchanger cores can be fouled by airborne particulate matter. In this study, the influence of particulate fouling on the membrane-based ERVs was investigated via accelerated material- and core-level fouling experiments. The core-level experiments, inside an aerosol wind tunnel (AWT), investigated the effect of dust accumulation on the performance of cross-flow cores (including sensible and latent effectiveness, and pressure drop) through comparing pre- and post-fouling performance tests of two core samples. The influence of the membrane surface exposed to particle-laden air, and working airflow rates were considered during AWT tests.
