Q3. Consider a refrigerator operating on an ideal vapour-compression refrigeration cycle between pressures of 0.8435 and 8.8672 bar and using R134a as the working fluid. Pressure drops in the evaporator and condenser may be neglected. (a) . Sketch the cycle on the T-s diagram. Sketch the cycle on the p-h diagram including labels for the components on the diagram, heat and work transfers, as well as the pressure values given above. Name three assumptions made about the compression process in an ideal vapour compression refrigeration cycle.
