Saturated vapor R22 refrigerant leaves the evaporator and enters the compressor at 131.68 kPa. The refrigerant leaves the condenser as a saturated liquid at 40oC and enters the expansion valve at 36oC. Heat rejected from the condenser amount to 105 kW. The work to the compressor is 65 kJ/kg, while the heat loss from the compressor is 5.5 kJ/kg. A 7.4 kJkg of heat loss in piping between the compressor and condenser, Draw the p-h diagram (labeling the pressures and temperatures in each condition). Determine (a) the temperature of refrigerant entering the condenser and (b) calculate the refrigeration capacity in tons.

Question
Saturated vapor R22 refrigerant leaves the evaporator and enters the compressor at 131.68
kPa. The refrigerant leaves the condenser as a saturated liquid at 40oC and enters the
expansion valve at 36oC. Heat rejected from the condenser amount to 105 kW. The work to
the compressor is 65 kJ/kg, while the heat loss from the compressor is 5.5 kJ/kg. A 7.4 kJkg
of heat loss in piping between the compressor and condenser, Draw the p-h diagram
(labeling the pressures and temperatures in each condition). Determine (a) the temperature
of refrigerant entering the condenser and (b) calculate the refrigeration capacity in tons.
