Title
Effect of the interface heat exchanger in composite NH3/H2OH2O/LiBr absorption-refrigeration systems (EN)

Description
In previous publications, a high-efficiency, composite absorption-refrigeration system has been proposed, which was composed of two co-operating absorption units using NH3/H2O and H2O/LiBr solutions, respectively. The heat output from the NH3/H2O unit was employed to drive the H2O/LiBr unit. In the present work, the real performance of the system is predicted and the effect of the heat exchangers connecting the two co-operating units is examined. Under certain assumptions, the real coefficient of performance and other characteristics of the system are expressed in terms of the ambient temperature and the effectiveness, ε{lunate} of the interface heat exchanger. It is found that the effect of the latter is considerable, being more pronounced at the higher values of ε{lunate}. For example, a system operating under usual conditions at 25°C ambient temperature, obtains a theoretical performance coefficient ranging from 108 to 209% for ε{lunate} ranging from 40% to its theoretical value of 100%. © 1991.
