Summary

Control of relative humidity is an essential aspect of maintaining indoor air quality in an air-conditioned space. In this article, a desiccant wheel integrated air conditioner was studied for low-humidity air conditioning. The desiccant wheel dehumidifies and heats the supply air. Regeneration of the desiccant is accomplished by the return air, which is cooled and humidified. The study showed that the proposed system can deliver supply air with a much lower dew point temperature compared with conventional systems with a marginal penalty on COP. Its performance is better than the typical reheat system used to provide the same low humidity levels.
