This invention relates to an alcohol reclaiming circuit for use in an absorption refrigeration system for maintaining the system at a constant high level of operation.
It has long been recognized in the absorption refrigeration art that the addition of alcohol to the working fluids contained within the system greatly enhances the overall performance of the system. Although the exact mechanism involved is not fully understood, the results obtainable can be dramatically demonstrated in practice. Often times, an increase in performance in excess of thirty percent (30%) can be immediately realized by the introduction of a small amount of alcohol into the system. However, it has heretofore been difficult, if not impossible, to sustain this high level of operation for any appreciable period of time. Experience has shown that the gain in performance that is initially achieved continually diminishes with time until the gain is ultimately reduced to zero. It has heretofore been the common practice to add more alcohol to the system When performance drops below a predetermined level. This procedure, however, is not entirely satisfactory in that it requires continual monitoring of the system's performance, produces an undesirable buildup of alcohol within the system, and results in unwanted variations in overall machine performance.
