Title
(DE) R718*-VERDICHTER MIT AKTUATOREN ZUM VOLUMENVERHÄLTNIS
(EN) R718* COMPRESSOR WITH ACTUATORS FOR THE VOLUME RATIO
(FR) COMPRESSEUR AU R718* AYANT DES ACTIONNEURS POUR LE RAPPORT VOLUMIQUE
Abstract
(DE) Die Erfindung bezieht sich bei Rotationsverdrängermaschinen auf die Verdichtung von Wasserdampf als Kältemittel R718 mit und ohne Zugabe von Zusatzstoffen als wässrige Lösung insbesondere für die Kälte-, Klima- und Wärmepumpen-Technik. Um im Betrieb die effizienzschädliche Über- oder Unterverdichtung stets bestmöglich zu vermeiden, wird in Fortsetzung der Schrift DE 10 2020 000 350.8 zur möglichst einfachen Einstellung des effektiv wirksamen inneren Volumenverhältnisses über iV-Scheiben (3) erfindungsgemäß vorgeschlagen, dass je iV-Scheibe (3.j) mindestens 3 Aktuatore (6.j) derart wirken, dass der zu bewegende iV-Scheibenstapel (3.s) längs der neutralen Achse AN mit Unterstützung durch Widerlager-Aktuatore (6.w) jeweils über ein Paar Positionsführungsstiften (4) bewegt wird, wobei zur Vermeidung hoher Adhäsionskräfte zwischen den iV-Scheiben abgestufte Kontakt-Flächen (KF) als Abdichtung vorgesehen sind.
(EN) The invention relates to the compression of steam in the form of R718 refrigerant with or without the addition of additives in the form of an aqueous solution in rotational displacement machines, in particular for refrigeration, air-conditioning and heat pump technology. In order to prevent over-compression or under-compression, which impairs efficiency, as optimally as possible during all operations and in continuation of DE 10 2020 000 350.8 on adapting the effective internal volume ratio as simply as possible via iV discs (3), according to the invention for each iV disc (3.j) at least 3 actuators (6.j) act such that the iV disc stack (3.s) to be moved is moved along the neutral axis AN with support from counter-bearing actuators (6.w), in each case via a pair of position guiding pins (4), wherein, in order to avoid high adhesion forces between the iV discs, stepped contact faces (KF) are provided as sealing.
(FR) L'invention se rapporte à la compression de vapeur sous forme d'un fluide frigorigène R718 avec ou sans ajout d'additifs sous la forme d'une solution aqueuse dans des machines à déplacement rotatif, en particulier pour la technologie de réfrigération, de climatisation et de pompe à chaleur. Afin d'éviter une surcompression ou une sous-compression, ce qui altère l'efficacité, de manière aussi optimale que possible pendant toutes les opérations et dans la continuation du document DE 10 2020 000 350.8 lors de l'adaptation du rapport volumique interne effectif aussi simplement que possible par le biais de disques iV (3), selon l'invention pour chaque disque iV (3.j), au moins 3 actionneurs (6.j) agissent de telle sorte que l'empilement de disques iV (3.s) à déplacer soit déplacé le long de l'axe neutre (AN ) avec un support à partir d'actionneurs à contre-palier (6.w), dans chaque cas par le biais d'une paire de broches de guidage de position (4) ; afin d'éviter des forces d'adhérence élevées entre les disques iV, des faces de contact étagées (KF) sont fournies en tant qu'éléments d'étanchéité.
