Abstract

L'invention concerne une machine frigorifique à absorption contenant un évaporateur pour évaporer un fluide frigorigène à basse pression, un absorbeur pour l'absorption de la vapeur de fluide frigorigène produite dans l'évaporateur par un solvant pauvre en fluide frigorigène à basse pression, une pompe de solvant pour refouler le solvant riche en fluide frigorigène à une plus haute pression, des moyens pour générer de l'eau chaude, un extracteur parcouru par l'eau chaude pour évaporer le fluide frigorigène hors du solvant, et un condenseur pour liquéfier la vapeur de fluide frigorigène à la plus haute pression, se présentant sous la forme d'un échangeur de chaleur parcouru par du liquide de refroidissement, qui est disposé dans le même boîtier que l'extracteur. La machine frigorifique à absorption selon l'invention est caractérisée en ce que l'évaporateur et l'absorbeur sont disposés dans un boîtier commun et forment ainsi un module absorbeur-évaporateur, qui peut être connecté à un module extracteur-condenseur. En l'occurrence, l'extracteur et le condenseur sont disposés dans un boîtier commun, le module absorbeur-évaporateur et le module extracteur-condenseur sont munis de raccords, auxquels peuvent se raccorder, de manière amovible, des composants de même type de modules de même type, et chaque module peut être raccordé de manière amovible à un agencement d'alimentation commun dans lequel sont disposés des dispositifs de commande et la pompe de solvant.
