The refrigeration system of Fig. P11–123 is another
Chapter 11, Problem 123P(choose chapter or problem)
11-123 The refrigeration system of Fig. P11-123 is another variation of the basic vapor-compression refrigeration system which attempts to reduce the compression work. In this system, a heat exchanger is used to superheat the vapor entering the compressor while subcooling the liquid exiting from the condenser. Consider a system of this type that uses refrigerant-134a as its refrigerant and operates the evaporator at \(-10.09{ }^{\circ} \mathrm{C}\), and the condenser at . Determine the system COP when the heat exchanger provides \(5.51{ }^{\circ} \mathrm{C}\) of subcooling at the throttle valve entrance. Assume the refrigerant leaves the evaporator as a saturated vapor and the compressor is isentropic.
