In this study, an ORC-VCC system driven by solar energy combined with electric motor is proposed to ensure smooth operation under the conditions that solar radiation is unstable and discontinuous, and an office building located in Guangzhou, China is selected as a case study. The results show that beam solar radiation and generation temperature have considerable effects on the system performance. There is an optimal generation temperature at which the system achieves optimum performance. Also, as a key indicator, the cooling power per square meter collector should be considered in the hybrid solar cooling system in design process. Compared to the vapor compression cooling system, the hybrid cooling system can save almost 68.23% of electricity consumption.}, DOI = {10.32604/EE.2020.014016} }
