The share of electricity consumption attributed to space climate control and cooling is steadily increasing worldwide. This consumption is primarily due to the use of conventional refrigeration machines that draw their driving energy from public power grids. In contrast, global solar radiation can also be converted into electricity or heat to serve as driving energy for cooling processes. This book addresses the potentials and technologies for this purpose. The thermal drive of sorption systems is considered the most promising alternative. Among thermally driven refrigeration machines, the processes of absorption and adsorption for generating cold have particularly gained traction. Devices in larger performance classes are now offered by various manufacturers and are finding buyers against the backdrop of government support.
