Résumé

In this paper, the drop formation properties of a lithium bromide salt solution Trane, which is utilized in a new concept of spray absorber, is investigated. In the spray absorber of the absorption refrigeration cycles, the feasibility of forming droplets with an optimum diameter of 300 micrometers, calculated by the drop absorption model, were studied. To achieve above, a single nozzle spray chamber able to attain a low-pressure of 1.23 kPa (0.178 psia) pressure was built. The nozzles experimentally tested were swirl-jet nozzles. The differential pressure across the nozzles was varied from 50 to 200 kPa (7.25-29 psia). The flow rate in the experiment was varied between 0.018 and 0.043 kg/s. The nozzles tested were able to produce drop sizes having a mean volumetric diameter between 375 and 425 micrometers. Comparison of drop absorption model results to conventional absorber results shows a significant improvement in absorption. [Reprinted with permission from Elsevier. Copyright, 2007].
