Theoretical and experimental investigations on the recirculation of the solution (mix-flow) in a NH3-H2O-absorption resorption refrigeration system.

Summary

Ammonia water absorption resorption refrigeration systems do not need a rectification column like conventional absorption refrigeration systems do. In this case such systems need a recirculation of the solution. This so called “mix flow” is necessary to prevent the dilution of the solution in the “cold cycle” of the system which is caused by the relative high concentration of water in the hot vapor. The influence of this recirculation of the solution on the performance of the system could be shown in previous studies and is now modelled and investigated more in detail. As a result of the theoretical investigation, a preferred internal piping layout is proposed. In addition, the theoretical foundations are verified with experimental investigations at an existing test cycle.
