Abstract: Dehumidification capacity and dehumidification coefficient of performance are employed to
evaluate the performances of desiccant wheels in this paper by experimental comparison of distribution
of operating parameters, such as process air inlet temperature and relative humidity, process air speed
regeneration air speed, and regeneration air inlet temperature. The results showed that at high inlet
temperature of process air, dehumidification performance of PPS/PPM 50% wheel was the best
compared with PPS silica gel wheel and PPM molecular sieve wheel; PPS silica gel wheel was more
suitable for environmental conditions of relatively high humidity; the increase of process air flow rate
was helpful to improve the performance of PPM molecular sieve wheel; when regeneration temperature
increased from 60C to 80C, dehumidification coefficient of performance and dehumidification
capacity of three desiccant wheels almost doubled
Key words: rotary desiccant wheel; silica gel; molecular sieve
