Title (EN) HEAT PUMP AND METHOD FOR OPERATING A HEAT PUMP
(FR) POMPE À CHALEUR ET PROCÉDÉ DE FONCTIONNEMENT D'UNE POMPE À CHALEUR
(DE) WÄRMEPUMPE UND VERFAHREN ZUM BETREIBEN EINER WÄRMEPUMPE
Abstract:
(EN) The invention relates to a heat pump (12, 26) comprising at least one evaporator (10), a subsequent downstream compressor (7a, 7b, 7), a subsequent downstream liquefier (8), and at least one subsequent downstream expansion device (9a, 9b, 9) for expanding the fluid, characterised in that, along the fluid circuit, there are arranged at least two expansion devices (9a, 9b) in series between the liquefier (8) and evaporator (10) and at least two compressors (7a, 7b) in series between the evaporator and liquefier, wherein a separator (30) for separating a gas phase and liquid phase is arranged between the two expansion devices for introducing steam between the compressors, and there are arranged means (34) for superheating the fluid (2) flowing from the evaporator.
(FR) L'invention concerne une pompe à chaleur (12, 26) qui comprend au moins un évaporateur (10), un compresseur (7a, 7b, 7) qui suit en aval, un condenseur (8) qui suit en aval et au moins un dispositif d'expansion (9a, 9b, 9) qui suit en aval pour l'expansion du fluide. L'invention est caractérisée en ce qu'au moins deux dispositifs d'expansion (9a, 9b) sont montés en série entre le condenseur (8) et l'évaporateur (10) le long du circuit du fluide et au moins deux compresseurs (7a, 7b) sont montés en série entre l'évaporateur et le condenseur. Un séparateur (30) destiné à séparer une phase gazeuse et une phase liquide est interconnecté entre les deux dispositifs d'expansion pour introduire de la vapeur entre le compresseur, et des moyens (34) y sont disposés pour surchauffer le fluide (2) qui s'écoule hors de l'évaporateur.
(DE) Die Erfindung betrifft eine Wärmepumpe (12, 26) mit mindestens einem Verdampfer (10), einem stromab nachfolgenden Verdichter (7a, 7b, 7), einem stromab nachfolgenden Verflüssiger (8), und mindestens einer stromab nachfolgenden Expansionsvorrichtung (9a, 9b, 9) zur Expansion des Fluids, dadurch gekennzeichnet, dass entlang des Fluidkreislaufs zwischen Verflüssiger (8) und Verdampfer (10) mindestens zwei Expansionsvorrichtungen (9a, 9b) in Reihe und zwischen Verdampfer und Verflüssiger mindestens zwei Verdichter (7a, 7b) in Reihe angeordnet sind, wobei ein Abscheider (30) zur Trennung einer Gas- und Flüssigphase zwischen den beiden Expansionsvorrichtungen zwischengeschaltet ist zur Einleitung von Dampf zwischen die Verdichter, und Mittel (34) zur Überhitzung des aus dem Verdampfer strömenden Fluids (2) angeordnet sind
