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.

Question
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.
