摘要：

The present study aims to integrate desiccant dehumidification systems and vapor-compression air conditioning (VC) systems for energy-efficient air conditioning applications. A numerical model is developed for a dehumidifier/regenerator module based on the governing mass, energy, and species balance equations. Subsequently, the desiccant system is integrated with the VC system to investigate the overall system performance. The novelty of the present work is in its exploration of the integration of desiccant systems. The share of dehumidifier load in overall system is studied, and performance of the integrated system is compared with that of a standalone VC system. Trade-off analysis is also performed in consideration of all performance parameters. The comparative results reveal that a significant amount of the total latent heat load is controlled by the dehumidifier. Specifically, it is observed that the integrated system can improve the COP by 40.8-74.8% relative to the standalone VC system under different operating conditions.
