The vapor compression refrigeration is one of the many refrigeration cycles and is the most widely used method for air-conditioning of buildings. On the other hand, solar thermal energy can be used to efficiently cool in the summer. Single, double or triple iterative absorption cooling cycles are used in different solar thermal cooling system designs. Absorption chillers operate with less noise and vibration than compressor-based chillers, but their capital costs are relatively high. In this study, a system is proposed as a combination of the aforementioned systems and the power consumption is minimized using cold thermal energy storage (CTES).
