Plate Heat Exchanger: Study and Experimental analysia of Plate Heat Exchanger used in Vapour Absorption Chiller.

In this book, a facility for experimental evaluation of innovative components forming part of a single effect Plate Heat Exchanger is analyzed. The adopted methodology has been mainly experimental. Plate heat exchangers functioning as generator, solution heat exchanger, condenser and subcooler have been incorporated in the design. Two adiabatic absorber configurations, droplets and liquid sheets, were tested and evaluation parameters were experimentally determined.Overall test facility performance is analyzed in the first stage of the research. The preliminary analysis gives an idea about the operational features of the machine, which allow subsequent detailed components analysis. This analysis is oriented to the interpretation of experimental data including the particular features, in both design and operation, of the facility here presented: study of evaporators’ efficiency, solution heat exchanger efficiency and thermal losses. Performance parameters, cooling capacity and COP, are expressed in terms of a diagnostic absorption model and compared with experimental results. The differences observed between ideal and experimental results help to validate the influence of component
