Study of air supply and humidification at double dew points in high moisture conditions

Aiming at the existing problems of traditional air conditioning in manufacture workshops with high temperature and moisture, presents the method of air supply and humidification at double dew points. The air is treated to different dew points through two spray rooms, then evenly sent into the workshops and finally mixed in order to remove the residual heat and moisture, which can keep high moisture in manufacture workshops. Theoretical analysis and engineering practice results indicate that, if the cold source condition is allowed, applying the method can reduce air changes and operation costs, and save energy significantly.
