Solar Climatization and Refrigeration

Solar heat can also be used as a thermal drive to operate refrigeration and air conditioning systems. Starting from the definition of refrigeration and air conditioning, a quantification of the power demand and a description of different methods for refrigeration and cooling is given. In particular, thermally driven refrigeration processes such as closed-loop absorption and adsorption processes are presented, their operation and plant design are explained, and their limitations are discussed. A further class of air-conditioning is formed by open sorption-based systems, the basic ideas and performance of which are discussed. Finally, a comparison of the technical options is given.
