Abstract
U ovom diplomskom radu detaljno je opisan i napravljen proračun kombiniranog ORC–VCC ciklusa za hlađenje i proizvodnju električne struje. Prilikom eksergijske i energijske analize sustava dobivene su vrijednosti brojnih parametara, a neki najvažniji od njih su faktor hlađenja (COPS), eksergijska učinkovitost sustava (ηe,sys), omjer tlakova u turbini (TPR) i ukupni maseni protok radnog fluida po kilovatu rashladnog kapaciteta (ṁtotal). Mnogi ugljikovodici, fluorugljikvodici, fluorugljici predlagani su kao radni fluidi za iskorištavanje energije niskotemperaturnih izvora. Utjecaj drugih parametara poput temperatura kotla, kondenzatora, isparivača zajedno s izentropskom učinkovitosti turbine i kompresora također su uzimani u obzir. Rezultati su pokazali da se najbolje performanse sustava postižu s radnim fluidom koji ima visoku kritičnu temperaturu. Između predloženih radnih fluida R602 pokazao se kao idealan izbor zbog superiornih termodinamičkih i ekoloških svojstava, ali zbog zapaljivosti potrebne su posebne mjere opreza.
Abstract (english)
In the present study, the performance of an integrated organic Rankine cycle-vapor compression refrigeration (ORC-VCR) system is investigated from the viewpoint of exergy and energy analysis. The system performance was represented by system coefficient of performance (COPS), system exergy efficiency (ηe,sys), turbine pressure ratio (TPR) and total mass flow rate of the working fluid for each kW cooling capacity (ṁtotal). Many common and new hydrocarbons, hydrofluorocarbons, fluorocarbons, were suggested as working fluids for for low-grade thermal energy use. The influences of various parameters such as the boiler, condenser and evaporator temperatures, along with compressor and turbine isentropic efficiencies, on the system performance were also investigated. The results revealed that the best system performance was attained with the uppermost critical temperature dry working fluid. Among all suggested candidates, R602 is shown to be the most suitable working fluid for the ORC-VCR system from system performance and environmental issues viewpoints. viewpoints. However, due to its flammability, extra precautions should be taken.
