Abstract
Separate Sensible and Latent cooling (SSLC) has been discussed in open literature as means to improve air
conditioning system efficiency. The main benefit of SSLC is that it enables heat source optimization for the
different forms of loads, sensible vs. latent, and as such maximizes the cycle efficiency. In this paper I use a
thermodynamic analysis tool in order to analyse the performance of various SSLC technologies including:
multi-evaporators two stage compression system, vapour compression system with heat activated desiccant
dehumidification, and integrated vapour compression with desiccant dehumidification. A primary coefficient
of performance is defined and used to judge the performance of the different SSLC technologies at the
design conditions. Results showed the trade-off in performance for different sensible heat factor and
regeneration temperatures.
