Developed and developing countries which like our country, needed a lot of energy in various study areas. So, resources should be use more efficiently. Cogeneration and trigeneration systems are one of the most efficient fuels systems which uses of resources. Trigeneration systems are both produce electricity and cooling and heating systems which are less fuel consumption then seperated systems.In this study, energy and exergy analysis is performed of trigeneration system which worked with natural gas. For each point, enthalpy, entropy, pressure and temperature values are obtained from attached tables of this study and presented with tables.Also, is calculated for each unit of irreversibility, entropy production, loss of energy, and the second law yields. Units were determined which maximum loss occurs, this appeared to be done to improve the units. Specified causes of the loses and presented a possible solution.The termal efficiency of cogeneration system which produce 91MW electrical energy was found %32, exergy efficiency was found %39. Termal efficiency of absorption cooling system, exergy efficiency and performance of cooling coefficient was calculated, respectively %63, %11, 0.753 and seemed to show parallelism in literature studies. Keywords: Trigeneration systems, energy ve exerg analysis, first ve second law analysis, absorption cooling
