Summary

THE PERFORMANCE OF ABSORPTION MACHINES IS GREATLY AFFECTED BY THE CHARACTERISTICS OF HEAT AND MASS TRANSFER IN THE ABSORBER. IN MOST COMMERCIAL ABSORPTION MACHINES, ABSORPTION ENHANCEMENT HAS BEEN DONE BY ADDING SMALL AMOUNTS OF VARIOUS KINDS OF SURFACTANTS, THEREBY REDUCING THE SURFACE TENSION OF THE ABSORPTION SOLUTION DRASTICALLY AND GENERATING MARANGONI CONVECTION NEAR THE SOLUTION SURFACE AT THE TIME OF REFRIGERANT VAPOUR ABSORPTION. THIS ARTICLE SUMMARIZES RECENT DEVELOPMENTS IN ABSORPTION ENHANCEMENT TECHNOLOGY, SUCH AS HIGH PERFORMANCE ABSORPTION TUBES AND THE MARANGONI CONVECTION GENERATING TECHNOLOGY.
