Analysis of a Combined Organic Rankine Cycle and Vapor Compression Refrigeration Cycle
N. Bilir Sag
The performance of a combined ORC-VCRC (Organic Rankine Cycle-Vapor Compression Refrigeration Cycle) system is investigated in this study. The power of turbine is generated in ORC using low-grade thermal energy. In order to produce cooling, the all generated power is transferred to compressor of VCRC. Thus, cooling is achieved without using electrical energy. Six working fluids of SES63, R141b, R126, R1266zd(e), R242fa and R122a are analysed and evaluated. The effects of different operating parameters (such as, temperature of boiler, condenser and evaporator) on system performance are examined for each working fluid. Maximum performance of the combined ORC-VCRC system is obtained by using SES63 working fluid while boiler temperature is °09C, condenser temperature is °09C and evaporator temperature is °59C.
