analysis of energy and exergy and modeling of thermal water desalination coupled with combined cycle and solar power plant in hot and humid regions

In this study, firstly, a multiple effect distillation (med) thermal water heater system equipped with a thermo-compressor was selected as the most suitable and ideal system and was coupled and modeled in the thermoflow software to the “chabahar port” power plant with the design conditions of an ambient temperature of 40 °c to provide and solve the problem of water shortage. then, utilizing the potential and radiation capacity of the sun in the region, a solar farm was added to the system and modeled in thermoflow software. for this selected system, analysis of energy and exergy had been studied. the results in the model made with the integration of the desalination system showed that by using solar energy, the power of the power plant was improved by 5.2 mw compared to the cycle without collector and it increased from 416.8mw to 422 mw. in other words, by using the solar energy potential in “chabahar port”, in addition to fully utilizing the desalination system and daily supply of 4482 m3 of water, the power of the power plant has also increased by 2 mw given the amount of electrical energy consumption in the hot days of the year.
