Dm. Manole et Jl. Lage, THERMODYNAMIC OPTIMIZATION METHOD OF A TRIPLE EFFECT ABSORPTION SYSTEM WITH WASTED HEAT-RECOVERY, International journal of heat and mass transfer, 38(4), 1995, pp. 655-663
A detailed performance study is done for a water-lithium bromide tripl
e regenerative effect absorption refrigerating system, with heat recov
ery. An analysis method is developed and implemented on a computer cod
e to simulate the operation and control of the system under realistic
conditions. The thermodynamic performances of the system are described
by means of exergetic and energetic based criteria. The numerical res
ults revealed that, by recovering wasted thermal energy into a heating
effect, the system global exergetic efficiency is sensibly increased.
It is also demonstrated that the amount of heat produced by the syste
m decreases with the temperature of the heating effect while the globa
l exergetic efficiency is increased.
