Question 2 A gas fired single-effect LiBr-H20 absorption refrigeration system as shown in Figure-2(a), operates with an evaporator temperature of 10 °C and condenser temperature of 42 °C. The mass flow rate of the solution delivered by the pump is 0.70 kg/s and the concentrations of the weak and strong solutions are 52% and 66% by mass, respectively. 3 Condenser Generator 52 66% 8 Evaporator +6 Absorber Figure-2(a) Schematic diagram of a single effect LiBr-H20 absorption refrigeration cycle (a) Determine the mass flow rates of the solution returning from the generator to the absorber and the mass flow rates of the refrigerant through the system. (b) If the generator is operating at 100 °C and the absorber at 35°C, determine, with the aid of the diagrams and tables provided, the rates of heat transfer in the following components: Generator ii. Absorber iii. Condenser iv. Evaporator 1.
