Abstract

a. Elément de déshumidificateur à froid pour l'air comprimé, composé de deux échangeurs de chaleur. b. L'échangeur de chaleur air-air 1 et l'échangeur de chaleur air-frigorigène 2 composant l'élément présentent des spires hélicoïdales, dont la longueur est égale à une spire et demie. L'échangeur air-air 1 comporte un tube extérieur 3 et au moins trois tubes intérieurs 4, tandis que l'échangeur air-frigorigène 2 comporte un tube extérieur 3 et, disposé à son intérieur, un tube coaxial 5 contenant à son tour des tubes intérieurs 4 qui sont en contact linéaire. c. Cet agencement simplifie la fabrication des éléments en respectant les valeurs spécifiées pour la puissance d'échange de chaleur, la perte de pression, etcat. Cold dehumidifier element for compressed air, consisting of two heat exchangers. b. The air-to-air heat exchanger 1 and the air-to-refrigerant heat exchanger 2 making up the element have helical turns, the length of which is equal to one and a half turns. The air-to-air exchanger 1 comprises an outer tube 3 and at least three inner tubes 4, while the air-refrigerant exchanger 2 comprises an outer tube 3 and, arranged inside it, a coaxial tube 5 containing in turn inner tubes 4 which are in linear contact. vs. This arrangement simplifies the manufacture of the elements while respecting the values specified for heat exchange power, pressure loss, etc.
