Abstarct: Increasing demand for energy, rising energy costs and increased environmental concerns has led governments to develop and improve technologies for saving energy and reducing emissions that lead. Cogeneration systems for cooling, heating and power (CCHP) and Organic Rankine Cycle (ORC) technology, which reduces the consumption of primary energy, reduce costs and emissions are reduced. Organic Rankine cycle is similar Rankine cycle, only the organic fluid as the working fluid used. Heat can be recovered from the cogeneration system is used to generate electricity in ORC. In this study the software (EES) to energy analyze system (CCHP-ORC) has been investigated. How to balance the needs of users have been investigated, as well as by changing the temperature of the evaporator inlet and outlet fluid temperature changes ORC thorough exergy efficiency is investigated. Given the amount of thermal energy and electrical requirements for the three cases considered. In the first case PGU, absorption chiller with heating coil and eliminates the need for users and there is no need for an additional boiler. ORC with the electric chiller are turn off. Latter two is divided adjustable within and outside the adjustable range. In the third case due to the power of the ORC used. Finally, energy and exergy efficiency of dry fluids tested and R141b more thorough exergy efficiency of the fluid as the fluid is introduced. In addition, ORC simple system at various temperatures was studied and it was found thorough exergy destruction of the system decreases with increasing temperature.
