Abstract

Nowadays, the application of renewable energy sources is one of the primary goals to contribute to low greenhouse gas emissions and low energy cost. Geothermal energy is one of the most attractive renewable energy sources that can be exploited at low, medium and high enthalpy. Absorption chillers are cooling machines that can be powered by a low-grade geothermal energy source. The geofluid leaving the power plant can be used to provide heat for the desorber before it is reinjected to the reinjection well. In this work, a thermodynamic analysis of parallel flow double effect water/LiBr absorption chiller driven by geothermal energy is presented. The effects of many design parameters such as temperature, mass flow rate, and heat exchanger size on the coefficient of performance (COP) and cooling load are investigated. An Engineering Equation Solver (EES) is used for that purpose. The results are presented in graphical forms to show the chiller performance behavior under different operating conditions. The results show that COP and cooling load can reach about 1.43 and 420 kW for certain operating and design conditions.
