A refrigerator operates between temperature limits of 30°C and -5°C. The refrigerant is 0.97 dry before leaving the evaporator coil. Find the condition of refrigerant entering the evaporator and COP of system. If the temperature rise of water circulating through the condenser is limited to 20°C, calculate mass flow rate of the coolant. Use the properties of refrigerant from table given below:
Take Cpfor superheated vapour as                                    3.35 kJ/kg ·K.
