ABSTRACT
The absorption heat transformer (AHT) systems are devices with the unique capability
of raising the temperature of low or moderately warm waste heat sources to more
useful levels. In the current work, an absorption heat transformer cycle operating with
the water/lithium bromide mixture connected to a water desalination unit is studied.
For the purpose of performance analysis and parametric study, the cycle is modeled in
the Engineering Equation Solver (EES) software. Then, a parametric analysis is carried
out on the system to study the effect of variation of some important design parameters
on the considered system. Results of the parametric study show that the COP of the
cycle highly depends on the outlet temperature of the absorber heat exchanger. Also,
the COP of the cycle decreases by increasing temperature of the condenser.
Furthermore, the cycle's COP is moderately increasing as the source temperature
increases too. This is also found that the highest exergy destruction happens in the
absorber. The amount of produced fresh water via desalination unit at the optimized
condition is estimated as 0.1783 kg/s.
