1.1. The case study

The main purpose of this study is the comparison between the performance of different concepts for DEC systems in Mediterranean climates. This comparison will be performed on a first and second law perspective; the analysis will be applied to the following systems: •

thermal load QL = 2.5 kW and a sensible thermal load QS = 7.5 kW. In Table 1 the design indoor and outdoor conditions are reported, as well as the inlet air conditions, determined by assuming an inlet air flow

ma = 1 kg/s (Va ~ 3200 m3/h); the regeneration air flow is equal to the process air. The design outdoor conditions are typical of a hot and humid climate, such as the one occurring in the countries of the Mediterranean area.
