A two-evaporator compression refrigeration system as shown
Chapter 11, Problem 60P(choose chapter or problem)
11-60 A two-evaporator compression refrigeration system as shown in Fig. P11-60 uses refrigerant-134a as the working fluid. The system operates evaporator 1 at \(0^{\circ} \mathrm{C}\), evaporator 2 at \(-26.4^{\circ} \mathrm{C}\), and the condenser at . The refrigerant is circulated through the compressor at a rate of \(0.1 \mathrm{~kg} / \mathrm{s}\) and the low-temperature evaporator serves a cooling load of
. Determine the cooling rate of the high-temperature evaporator, the power required by the compressor, and the COP of the system. The refrigerant is saturated liquid at the exit of the condenser and saturated vapor at the exit of each evaporator, and the compressor is isentropic.
