The diagram to the right shows a typical schematic of a simple refrigeration system. We will learn more about this complete system later in the semester, but for now we'll focus solely on the compressor. The only thing you must understand about this schematic for now is that the compressor receives refrigerant from the evaporator at Pevap, then delivers refrigerant to the condenser at some higher pressure, P cond. For the refrigeration system of interest here, the evaporator and condenser operate at 280 kPa and 700 kPa, respectively. Also, the refrigerant enters the compressor as a saturated vapor and exits the compressor at 40°C. If the compressor is adiabatic and steadily consumes 2.3 kW of electrical power, what is the mass flow rate of refrigerant through the compressor? Be sure to start your analysis from general balance equations. 4 Warm environment Он Condenser Expansion valve Evaporator QL Cold refrigerated space (2 Win Compressor 1
