Title
(EN) AIR CONDITIONER
(FR) APPAREIL DE CLIMATISATION
Abstract
(EN)
A process and the required apparatus for air conditioning the interior of a structure located within a harsh desert like exterior environment. A tube and shell heat exchanger wherein the shell side is wet and the tube side is dry is employed to air condition the interior of the structure. In the operation of the air conditioner, a mass of distributed water is established on the wet shell side, and a flow of ambient air is passed through the wet shell side to form a resulting stream of moist air. A flow of ambient air is passed through the dry tube side and a resulting stream of dry cooled air is recovered. The streams of moist and cooled air are combined and the resulting stream of combined air is discharged into the exterior of the structure. The structure is not hermetically sealed and the water consumption rate is generally less then conventional evaporative cooler.

L'invention concerne un procédé et un appareil associé permettant de climatiser l'intérieur d'une structure située dans un endroit désert de type environnement extérieur. Un échangeur de chaleur tubulaire à calandre, dans lequel le côté calandre est mouillé et le côté tube est sec, est utilisé pour climatiser l'intérieur de ladite structure. En fonctionnement, une masse d'eau répartie est positionnée sur le côté calandre mouillé de l'appareil de climatisation, et un flux d'air ambiant est passé dans ce côté calandre mouillé afin d'obtenir un flux d'air humidifié. Un flux d'air ambiant est passé dans le côté tube sec, ce qui permet d'obtenir un flux d'air sec refroidi. Les flux d'airs humidifié et refroidi sont combinés et le flux obtenu d'air combiné est introduit à l'intérieur de la structure. Ladite structure n'est pas fermée hermétiquement et son taux de consommation d'eau est en général inférieur à celui d'un refroidisseur à évaporation.
