The seasonal performance of a liquid-desiccant air conditioner.

Author(s) : LOWENSTEIN A., NOVOSEL D.

Summary

Prior reports on liquid-desiccant systems have focused on their steady-state operation at ARI design conditions. By studying their performance during an entire cooling season, the computer modelling presented here shows that liquid-desiccant systems can have a very high seasonal COP. For a liquid-desiccant system that uses a double-effect boiler, COPs ranging from 1.44 in a humid location (Houston) to 2.24 in a dry location (Phoenix) are achieved by fully exploiting indirect evaporative cooling and providing only the minimum latent cooling needed to meet the loads on the building. This minimizes the amount of water absorbed by the desiccant and, hence, the amount of thermal energy needed to regenerate it.
