Abstract
Solar thermal cooling technologies are based on the smart idea of using solar energy - which is what produces the very need for cooling in buildings - to create 'cold'. Present-day designs use refrigerants which are environmentally friendly. Using energy from the sun - which also has the benefit of being free of charge - helps to save primary energy and therefore also helps to 'keep the globe cold'. This article points out the growing need for cooling in general, describes opportunities to convert solar irradiation into cooling, describes the most common thermal technologies in more detail, together with their current market situation, and presents worldwide installation statistics. The article concludes with a discussion of the current market situation and obstacles to widespread market penetration, followed by an outlook for the coming years.
