QUESTION 1 A manufacturer conducted an experiment for an evaporator capacity 533 kW cooling and designed for high COP of 1.8 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 608 kW, determine: Heat provided by the generator & absorber capacity in kW (equating overall heat balance of all heat exchanger). Show in the Solution Paper: Heat provided by the generator Provide in the Answer Box: Absorber Capacity in kW Answer in two decimal places
