Summary

A thermodynamic analysis has been carried out to study the performance of double absorption heat transformers assuming water-lithium bromide as the working fluid. The performance of single and two-stage heat transformers analyzed in part 1, was compared with the performance of double absorption heat transformers under the same operating conditions. The results showed that single stage heat transformers were the simplest and most efficient. Greater absorber temperatures were reached with two stage heat transformers. However, these systems were in general less efficient than the others and technically the most complex. Double absorption heat transformers were technically simpler than two stage heat transformers and may reach absorber temperature as high as these systems.
