Abstract
In this study, application fields and potential of geothermal energy of Turkey are introduced. Then, steam ejector cooling systems using geothermal heat source are presented and thermodynamics of the system is explained. Energetic performance of the system (COP) is obtained by the first law of thermodynamics and exergetic performance of the system (COPEX) is obtained by the second law of thermodynamics. In this present study, generator temperatures for ejector cooling system, which will be designed suitably for geothermal fields with low and middle temperatures of Turkey, are selected at interval of two different temperatures (low and middle temperatures). Generator temperatures (Tg) are 60-90C for applications with low temperatures, and 100-130C for applications with middle temperatures. The energetic performance (COP) and the exergetic performance (COPEX) of the system are evaluated for three different conditions of evaporator temperature (Te = 5, 10, 15 C) and two different conditions of condenser temperature (Tc = 30, 35 C). The intervals of temperature for evaluating the system performances are obtained from the experimental steam ejector cooling system designed. The 96 different cases are examined and the results are presented with graphics.
