Energy and exergy analyses of a combined desalination and CCHP system driven by geothermal energy
چکیده انگلیسی
Renewable energy sources are gain more attention due to their advantages over the fossil fuels. In this paper, a modified Kalina cycle is coupled to a reverse osmosis system to provide heating, cooling and power and potable water. Hot geothermal water is used as heat source of the system. Energy and exergy analyses are used to analyze the system and evaluate its performance. Effect of key thermodynamic parameters on the system performance is studied using sensitivity analysis. The results show that the system can provide 46.77 kW power, 451 kW heating, 52 kW cooling and 0.79 kg/s potable water. Also, the sensitivity analysis shows that there is an optimum value for the flash pressure and inlet pressure to the first separator which should be selected wisely. It is concluded that the parameters related to the steam cycle are dominant ones because they can affect both the steam cycle and the Kalina cycle.
