A refrigerator uses refrigerant 134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. The refrigerant enters the evaporator at 120 kPa with a quality of 34 percent and leaves the compressor at 60 ºC. Determine (a) the condenser pressure, (b) the isentropic efficiency of the compressor, (c) the COP of the refrigerator.

Technician A says a refrigerant identifier is only needed when the technician is unsure of the refrigerant used in an AC system. Technician B says that some refrigerant identifiers can measure the amount of moisture in the refrigerant system to aid in diagnosis. Who is correct? A. Neither Technicians A nor B B. Both Technicians A and B C. Technician A D. Technician B

Consider a refrigerator that operates on the vapor compression refrigeration cycle with $\mathrm{R}-134 \mathrm{a}$ as the working fluid. The refrigerant enters the compressor as saturated vapor at $160 \mathrm{kPa}$, and exits at $800 \mathrm{kPa}$ and $50^{\circ} \mathrm{C}$, and leaves the condenser as saturated liquid at $800 \mathrm{kPa}$. The coefficient of performance of this refrigerator is $(a) 2.6$ $(b) 1.0$ $(c) 4.2$ $(d) 3.2$ $(e) 4.4$
