This Solar Thermal HVAC (ST-HVAC) system consists of two numbers of high optical efficiency, point focus, two-axis tracking solar concentrator of Fresnel design, called the ARUN concentrator dish. The ARUN dishes provide fry saturated steam at 180o C at about 200kg per hour. The steam is fed to a 50 TR (i.e. about 175 kW of cooling) Vapour Absorption Machine (VAM). In turn, the VAM utilizes the thermal energy of steam to produce the cooling effect. The distinguishing feature of the system is the storage tank that can store up to 2 days of chilling.
