Regenerative gas refrigeration cycle: Pressure Ratio = 5, Compressor inlet temp. = 00C, Turbine inlet temp. = - 800C, Regenerator inlet (from the compressor side) temp. = 350C, Efficiency of the turbine = 85% and the efficiency of the compressor = 80%. Consider constant specific heats with Cp = 1.005 kJ/kg. K, k = Cp/Cv =1.4. Determine: (a) The effectiveness of the regenerator, (b) the heat removal in kJ/kg, and (c) the COP of the cycle. Also, find the Refrigeration load in kJ/kg and the COP for a simple refrigeration cycle with rp = 5, compressor inlet temperature of 00C and turbine inlet temperature of 35oC
