Today, most of the energy used in the world is supplied by energy conversion systems using fossil fuels. Considering the limitations and environmental problems caused by the burning of fossil fuels, the use of renewable energy sources is a must. In this regard, geothermal systems can performe a significant role. In geothermal systems, a large amount of exergy is lost in heat exchangers, which results in lower efficiency.In order to reduce the irreversibility of the cycle, the temperature difference between the fluid and the geothermal fluid must be reduced and which is feasable. Which is to be used from duple working fluid with low and variable boiling point. In recent years, the use of ammonia-water mixtures has been considered. Another important category in energy conversion systems is the use of dual or triple production systems. It is proven that the use of these systems is more Economical than single production systems. So far, the technology literature of the cogeneration systems has been introduced and analyzed. However, in most of these systems, relative quantities of product production (for example, power and cooling) are constant, while relative demand for the two products varies at different times. The study system is a combination of Organic Rankin Cycle and an absorption refrigeration system in which a compressor is used at the absorber input (to raise) the adsorbent pressure and an expander to generate additional power. The EES software will be used for modeling and the basic design parameters will be specified along with a parametric study. Using these parameters, system performance will be optimized from the thermodynamic point of view (and, if possible, economically)
