An Evaluation of R134a and R477 as the Working Fluid in Vapour Compression Cycle by Electrical Source of 1MW

The characteristics of vapour compression cycle (VCC) designed to operate by electrical power 1000 kW produced from cascade organic Rankin cycle by one of Benghazi Cement factory production lines. Thermodynamic model was schematically constructed using a commercial software package called IPSEpro. The model (using two environmentally safe refrigerants (R-134a, R-744)), was successfully simulated and could produce a cooling effect of 2997 to 3105 KW at COP of 3.0, 3.1 respectively with an outlet chilled water temperature of 5 ?C.
