Abstract
In this study, the thermodynamic performance of a vapour compression refrigeration cycle (VCRC) in which an organic Rankine cycle (ORC) has integrated and that generates electricity by utilising a geothermal source is investigated. The system's energy and exergy performance has evaluated by using various refrigerants used in the ORC system, depending on the evaporator (ORC) temperature (70 degrees C-120 degrees C), and an exergoeconomic analysis has performed to determine optimum operating conditions. As a function of the refrigerant and evaporator temperature, the coefficient of performance (COPsys) of the integrated system has varied between 0.55 and 1.01, whereas the exergy efficiency has varied between 14.20% and 20.16%. The unit exergy cost of the cooled air has been determined as 27.22 USD/GJ under the optimum operating conditions.
