Problem#$2$ The operating conditions for water$-$lithium bromide chilled$-$water plant for air conditioning are as follows: $1-$ Generator temperature $972-$ Condenser temperature $403-$ Absorber temperature $40$ Find temperature of the solution entering generator assuming hot solution is cooled to the saturation temperature at absorber pressure. For evaporator temperatures of $5$ and $10$ Determine for $1$TR refrigeration, considering the two evaporator cases: a$)$ Thermodynamic conditions at all points. b$)$ Coefficient of performance $($COP$).$ c$)$ Mass flow rates at all sections. d$)$ Energy balance of complete system. e$)$ Compare the COP with the increase in the evaporator temperature.
