Question: refrigerant 134a enters an air conditioner compressor at 4 bar...
Refrigerant 134a enters an air conditioner compressor at 4 bar,
20°C, and is compressed at steady state to 12 bar, 80°C. The
volumetric flow rate of the refrigerant entering is 8.5
m3/min. The work input to the compressor is 127.5 kJ per
kg of refrigerant flowing.
Neglecting kinetic and potential energy effects, determine the magnitude of the heat transfer rate from the compressor, in kW.
