Abstract This thesis deals with the study of a particular Desiccant Cooling system using the regenerative indirect evaporative process for air conditioning purposes. The designed system is characterized by a desiccant wheel made of silica gel coupled with several indirect evaporative coolers. The components are modelled and the system is simulated during the summer period in Copenhagen and Venice, to cover the sensible and latent loads inside a typical Danish supermarket. Alternative solutions based on electrical and absorption chillers are also simulated, by means of simplified models, to compare their results. It is shown that the designed desiccant cooling system is a valid alternative to conventional systems based on electrical chillers when cheap heat is available, both from renewable energy sources or as waste heat from other processes. The required number of evaporative coolers in the desiccant cooling system is high, requiring a further optimization of the system to decrease its investment costs, making it more attractive.
