Proposal and comprehensive analysis of an innovative CCP plant based on an internal integration of double flash power system and ejector refrigeration cycle

Utilizing high-efficient systems for cooling and electricity generation from green energy resources is an efficient method of sustainable development. For this aim, an innovative hybrid cycle for simultaneous power and cooling generation is recommended. The presented system is an internal integration of double-flash ejector refrigeration and power systems. First-law and second-law analysis are employed to investigate the feasibility of the system. Besides, a single-objective optimization performed by the implementation of the GA technique. The optimal energy and exergy efficacies are achieved by 72.57% and 27.69%, respectively. Furthermore, a thorough parametric analysis indicated that the energy and exergy efficacies could be optimized according to turbine pressure and ejector pressure. Moreover, it is showed that a higher energy efficacy and cooling capacity is obtainable by augmenting the ejector pressure, evaporator temperature, and compressor pressure ratio. Whereas, the exergy efficacy can be enhanced by increasing condenser #2 pressure. Besides, based on the exergy efficacy of each constituent of the system, the flashing chamber 1 shows the most excellent exergy efficacy among all the constitutes while the highest value of exergy is destroyed within the condenser 1.
