In this work, two desalination systems combined with a solar energy cycle, MED-PF and MED-PF-TVC are analyzed and evaluated thermo-economically. Solar energy is directly transferred from the solar collector field via the evaporator heat exchanger to MED-PF. In the second technique, the thermal energy produced is transmitted to the steam ejector of the MED-PF-TVC. The comparisons are handled according to 5000 m3/day of distilled product as a case study. A reduction in consumption and specific energy costs is possible due to the reduction in the value of the compression ratio and the increase in the number of evaporators.
