Gemäß dem Patentanspruch 1 ist diese Aufgabe bei einer Vorrichtung der eingangs genannten Art dadurch gelöst, dass aus Stahlmaterialien gebildete Komponenten, die sowohl mit dem Fluid als auch mit der Umgebungsluft oder Stickstoff in Kontakt sind, chemisch vernickelt sind, dass Komponenten, die vollständig mit dem Fluid in Kontakt sind, insbesondere statisch verbaut sind und Spalte oder Abdichtungen zum benachbarten Bauteil aufweisen, zinkphosphatiert sind, dass Komponenten, die vollständig mit dem Fluid in Kontakt und zumindest in einem Betriebszustand von dem Fluid vollständig umspült sind, blank gelassen sind und dass aus Aluminiummaterialien gebildete Komponenten eloxiert sind.According to claim 1, this object is achieved in a device of the type mentioned above in that components formed from steel materials, which are in contact with both the fluid and the ambient air or nitrogen, are chemically nickel-plated components that are completely with the Fluid are in contact, in particular are statically installed and have gaps or seals to the adjacent component are zinkphosphatiert that components that are completely in contact with the fluid in contact and at least in an operating state of the fluid completely blank, are blank and made of aluminum materials formed components are anodized.
Die Verträglichkeit der Vorrichtung mit HFC-Fluid lässt sich nicht nur durch entsprechende Oberflächenbeschichtungen der zum Bau benutzten Komponenten erreichen, sondern kann auch bei schon vorhandenen Vorrichtungen durch Umrüstung realisiert werden, indem vorhandene Baugruppen HFC-tauglich gemacht werden, beispielsweise durch Zinkphosphatieren oder indem verzinkte Bauteile entzinkt und neu vernickelt werden.The compatibility of the device with HFC fluid can be achieved not only by appropriate surface coatings of components used for construction, but can also be implemented in already existing devices by retrofitting existing assemblies are made HFC suitable, for example by zinc phosphating or by galvanized components to be descaled and re-nickeled.
Mit Vorteil kann die Anordnung so getroffen sein, dass zumindest ein Ventil in einem Ventilblock als weitere Komponente eingebaut ist.Advantageously, the arrangement can be made such that at least one valve is installed in a valve block as a further component.
Der Ventilblock kann aus einem Aluminium-Werkstoff bestehen und auf seiner der Umgebung zugewandten Außenseite eloxiert sein.The valve block may be made of an aluminum material and anodized on its outer side facing the environment.
Bei Oberflächen der Komponenten, die vollständig von dem Fluid umspült sind, kann zur Vermeidung von Flächenkorrosion für die jeweilige Komponente vorgesehen sein, Aluminiummaterialien blank zu belassen oder zu eloxieren sowie Stahlmaterialien blank zu belassen oder zu zinkphosphatieren oder zu vernickeln sowie nichtrostende Edelstahlmaterialien einzusetzen.In the case of surfaces of the components which are completely surrounded by the fluid, to avoid surface corrosion for the respective component it may be provided to leave aluminum materials bare or to anodize and to leave steel materials bare or zinc-phosphated or nickel-plated and to use stainless stainless steel materials.
Hinsichtlich der Spaltkorrosion, d.h. der verstärkten, auf elektrochemischer Reaktion beruhenden Korrosion in Spalten oder Rissen zwischen zwei Körpern, kann bei Oberflächen der Komponenten, die eine elektrische Potentialdifferenz zwischen einem Spalt und einem Außenspaltbereich aufweisen und Dichtelemente zum Abdichten des Spaltes gegenüber dem Außenspaltbereich verwenden, zur Vermeidung von Spaltkorrosion für die jeweilige Komponente vorgesehen sein, Aluminiummaterialien zu eloxieren, Stahlmaterialien chemisch zu vernickeln, wobei der Phosphorgehalt in der Beschichtung mindestens 10 % aufweist, oder nichtrostenden Edelstahl einzusetzen.With regard to crevice corrosion, i. the enhanced, based on electrochemical reaction corrosion in crevices or cracks between two bodies can, for surfaces of the components having an electric potential difference between a gap and an outer gap area and sealing elements for sealing the gap relative to the outer gap area, to avoid crevice corrosion for the respective component be provided to anodize aluminum materials to chemically nickel steel materials, wherein the phosphorus content in the coating has at least 10%, or to use stainless steel.
Bei Oberflächen der Komponenten ohne eine elektrische Potentialdifferenz zwischen einem Spalt und einem Außenspaltbereich, zwischen denen kein Fluidaustausch stattfindet, und mit Nutverläufen in der jeweiligen Komponente, die zwei benachbarte Fluidräume mit dem Fluid gegeneinander abdichten, und mit zumindest einer nur eingeschränkt bewegbaren oder stationär angeordneten Komponente, kann zur Vermeidung von Spaltkorrosion für die jeweilige Ventilkomponente vorgesehen sein, Aluminiummaterialien zu eloxieren sowie zinkphosphatierte Stahlmaterialien einzusetzen.In the case of surfaces of the components without an electrical potential difference between a gap and an outer gap region, between which there is no fluid exchange, and with groove courses in the respective component, which seal two adjacent fluid spaces with the fluid against each other, and with at least one only limited movable or stationary component, may be provided to avoid crevice corrosion for the respective valve component, anodize aluminum materials and zinc-phosphated steel materials use.
Bei Oberflächen der Komponenten, die eine elektrische Potentialdifferenz zwischen Spalt und Außenspaltbereich aufweisen, kann bei Austausch von Fluid zwischen dem Spalt und dem Außenspaltbereich und mit Nutverläufen in zumindest einer Komponente, die zwei benachbarte Fluidräume gegeneinander abdichten, und mit mindestens einem bewegbaren Bauteil, zur Vermeidung von Spaltkorrosion für die jeweilige Komponente vorgesehen sein, Aluminiummaterialien blank zu belassen sowie Stahlmaterialien blank zu belassen.In the case of surfaces of the components which have an electrical potential difference between gap and outer gap region, fluid can be exchanged between the gap and the outer gap region and with groove profiles in at least one component which seal two adjacent fluid spaces against each other and with at least one movable component Crevice corrosion for the respective component be provided to leave bare aluminum materials and leave bare steel materials.
Ferner ist zur Vermeidung von Kontaktkorrosion die Oberfläche des Ventilblocks als der weiteren Komponente größer zu wählen als die Oberflächen der in den Ventilblock eingesetzten Komponenten im Bereich ihres Eingriffs in den Ventilblock.Furthermore, in order to avoid contact corrosion, the surface of the valve block as the further component is to be selected larger than the surfaces of the components inserted into the valve block in the region of their engagement in the valve block.
Hinsichtlich der zum Korrosionsschutz vorgesehenen Beschichtungen ist die Anordnung mit Vorteil so getroffen, dass die Schichtdicke des eloxierten Aluminiummaterials mindestens 10 µm, des chemisch vernickelten Stahlmaterials mindestens 10 µm und des zinkphosphatierten Stahlmaterials etwa 5 µm beträgt.With regard to the coatings provided for corrosion protection, the arrangement is advantageously such that the layer thickness of the anodized aluminum material is at least 10 μm, the chemically nickel-plated steel material is at least 10 μm and the zinc-phosphated steel material is approximately 5 μm.
