An ammonia absorption type water chilling/heating device comprising a generator (22) for generating high pressure ammonia gas (21) from an aqueous ammonia solution (11) by a heat source, a rectifier (28) for gas-liquid separation to provide the ammonia gas (21) and a dilute ammonia solution (9), a condenser (23) for condensing the ammonia gas (21) after separation, an evaporator (24) utilizing the cooling action produced when an ammonia solution (94) after condensation is vaporized, and an absorber (25) for causing the aqueous ammonia solution to absorb the ammonia gas (21) after vaporization, these parts being successively arranged from top so that the dilute ammonia solution (9) may move by gravity. Such arrangement allows omission of a rectifying tower and connection piping, and reduces the size of the evaporator and absorber, thus making it possible to further reduce the size of the entire device and to cope with a variety of heat sources.
L'invention concerne un dispositif de refroidissement/chauffage d'eau de type à absorption d'ammoniac. Ce dispositif comprend un générateur (22) qui génère de l'ammoniac à haute pression (21) à partir d'une solution d'ammoniac aqueuse (11) au moyen d'une source de chaleur, un redresseur (28) qui sépare le gaz du liquide pour obtenir l'ammoniac (21) et une solution d'ammoniac diluée (9), un condensateur (23) qui condense l'ammoniac (21) après ladite séparation, un évaporateur (24) qui utilise l'action de refroidissement produite lorsque la solution d'ammoniac (94) est vaporisée après condensation, et un absorbeur (25) qui amène la solution d'ammoniac aqueuse à absorber l'ammoniac (21) après vaporisation, ces parties étant successivement disposées en partant du haut de sorte que la solution d'ammoniac diluée (9) se déplace sous l'effet de la gravité. Cette disposition permet de s'affranchir de la présence d'une colonne de rectification et d'un tuyau de raccord, et de réduire ainsi la taille de l'ensemble du dispositif et de l'adapter à diverses sources de chaleur.
