Derive an expression for the COP of an ideal vapor compression refrigeration cycle in terms of Tc and Th (the evaporator and condenser saturation temperatures). Make the following assumptions in the derivation: - The refrigerant vapor behaves as an ideal gas and the liquid is incompressible - The heat of vaporization and heat capacities are independent of temperature - Assume comp is constant and use the average value computed from your data - The refrigerant used is R22 The work for adiabatic compression of an ideal gas from P1 and T1 to P2 is given by W=compnRT1[(P1P2)1]
