To improve the thermal efficiency of the mechanical vapor recompression (MVR) system in high-salinity wastewater evaporative crystallization process, a novel solar-assisted MVR system was proposed. Based on the numerical model, some key operation parameters were analyzed. Results showed that the proposed system required lower compression work, and as the NaCl mass concentration was lower than 2%, the coefficient of performance (COP) reached 24.96. As the concentration ratio of the evaporator increased from 4 to 12, the compression work increased by 71.5% and the collector area decreased by 72.9%. Lower flashing pressure was beneficial to reduce the system temperature and increase processing capacity, while the compression work increased.
