This paper compares the solar thermal absorption cooling and photovoltaic (PV) turbo cooling performance in Riyadh, Saudi Arabia using a System Advisor Model (SAM) program provided by NREL (National Renewable Energy Laboratory). The cooling capacity of the two cooling systems was set to 100 usRT under the irradiation condition at 12 PM in March. The PV cooling capacity was maximum 100 usRT in June and September, but it decreased to 80 usRT in December because of the lower irradiation. In the case of solar thermal absorption cooling, the performance was greater than 100 usRT in June and September but the performance was lower than PV cooling in December. The annual deviation of the cooling performance of the solar thermal cooling is larger than that of PV cooling. This is probably due to the large change in the optical efficiency of the solar thermal system. Therefore, it is necessary to optimize the installation capacity of the solar thermal cooling system.
