Title
(EN) AIR CONDITIONING PROCESS AND APPARATUS
(FR) PROCEDE ET APPAREIL DE CLIMATISATION
Abstract
(EN)
An air conditioning process and apparatus with absorption of water vapor in a circulating absorption liquid containing an aqueous salt solution. The absorption liquid to be supplied to the absorber (100) is cooled by indirect contact with a circulating water stream in a heat exchanger (103). The circulating water is expanded at reduced pressure to release water vapor and lower the temperature of the water. The water vapor is thereafter absorbed in absorption liquid from the absorber (101, 102).
(FR)
Un procédé et un appareil de climatisation à absorption de vapeur d'eau dans un liquide d'absorption en circulation, comprenant une solution aqueuse de sel. Le liquide d'absorption devant être amené à l'absorbeur (100) est refroidi par un contact indirect avec un courant d'eau circulant dans un échangeur thermique (103). L'eau en circulation est détendue à pression réduite afin de libérer de la vapeur d'eau et de baisser la température de l'eau. La vapeur d'eau est ensuite absorbée dans le liquide d'absorption provenant de l'absorbeur (101, 102).
