QUESTION 2 A manufacturer conducted an experiment for an evaporator capacity 535.9 kW cooling. Enthalphies of the refirgerant and solution are found to be: -143 solution leaving the Absorber -535.15 solution leaving the Generator 3257.32 refrigerant generated 168.02 refrigerant leaving the Condenser 2548.90 refrigerant absorbed determine: Mass flow of the refrigerant in kg/s Answer in four decimal places. QUESTION 3 A manufacturer conducted an experiment for an evaporator capacity 500 kW cooling and designed for high COP of 2 when using lithium bromide plus water in an absorption refrigeration system. The evaporator operates 20 C, condenser 40 C & absorber 45 C supplying 1.4 kg/s of water plus lithium bromide solution to the generator. For a condenser size of 650 kW, determine: Ethalphy of the refrigerant leaving the Evaporator in kJ/kg Answer in one decimal place(s)
