In an aqua-ammonia absorption refrigeration system of 8 TR capacity, the vapours leaving the generator are 100% pure NH3 saturated at 50°C. The evaporator, absorber, condenser, and generator temperatures are 10°C, 40°C, 50°C and 80°C respectively. At absorber exit (strong solution), the concentration of ammonia in solution is x = 0.38 and enthalpy h = 20 kJ/kg. At generator exit (weak solution) x = 0.2 and h = 700 kJ/kg. Determine a) Heat added in generator; and b) C.O.P. In an aqua-ammonia absorption refrigeration system of 8 TR capacity, the vapours leaving the generator are 100% pure NH3 saturated at 50°C.
