Theoretical study on separate sensible and latent cooling air-conditioning system.

Author(s) : LING J., HWANG Y., RADERMACHER R.

Summary

The advantage of separating sensible and latent cooling (SSLC) by using separate devices is to save energy by raising the evaporating temperature of the sensible cooling process. The latent cooling portion can be met either by vapour compression cycles or desiccant devices. The later can be achieved by using waste heat or other heat sources. The study presented here focuses on using two vapour compression cycles, one for sensible and one for latent cooling. Pertinent characteristics of the SSLC system are discussed, including: (1) the coincident of the maximum energy savings and the highest air flow rate through the system; (2) energy saving potential under varying sensible cycle outlet air temperatures; and (3) energy savings potential under varying ambient conditions.
