Refrigerating systems and heat pumps - Flexible pipe elements, vibration isolators, expansion joints and non-metallic tubes - Requirements, design and installation
This document describes requirements, design and installation of flexible pipe elements (e. g. metallic flexible pipe, metallic flexible tube, vibration isolator, expansion joint) and non-metallic tube used in the refrigerant circuits of refrigerating systems and heat pumps.
It also describes the requirements to qualify the tightness of non-metallic tubes (e.g. plastic) used in evaporating and/or condensing sides of refrigerating systems and heat pumps.
It does not apply to flexible pipes that are only occasionally stressed beyond the elastic limit, e. g. during repair work, or to joints which are free to rotate or hinge.
Kälteanlagen und Wärmepumpen - Flexible Rohrleitungsteile, Schwingungsabsorber, Kompensatoren und Nichtmetall-Schläuche - Anforderungen, Konstruktion und Einbau
Dieses Dokument gilt für flexible Rohrleitungsteile (z. B. biegsames Metall-Rohr, Metall-Schlauch,
Schwingungsabsorber, Kompensator) und für Nichtmetall-Schläuche in Kältemittelkreisläufen von Kälteanlagen
und Wärmepumpen.
Es legt auch Anforderungen zur Bestimmung der Dichtigkeit von Nichtmetall-Schläuchen (z. B. Kunststoff)
fest, die in Verdunstungs- und/oder kondensierenden Seiten von Kälteanlagen und Wärmepumpen angewendet
werden.
Es gilt nicht für biegsame Rohre, die nur gelegentlich über ihre Elastizitätsgrenze hinaus beansprucht werden,
z. B. bei Reparaturen, oder für drehbar gelagerte Verbindungen oder Rohrgelenke.
Systèmes de réfrigération et pompes à chaleur - Eléments flexibles de tuyauterie, isolateurs de vibration, joints de dilatation et tubes non métalliques - Exigences, conception et installation
Le présent document décrit les exigences, la conception et l’installation des éléments flexibles de tuyauterie,
(par exemple, tuyauterie flexible métallique, tuyaux flexibles métalliques, isolateurs de vibration, joints de
dilatation) ainsi que les tubes non métalliques utilisés dans les circuits de fluides frigorigènes des systèmes de
réfrigération et pompes à chaleur.
Elle décrit également les exigences pour qualifier l’étanchéité des tubes non métalliques (par exemple en
plastique) utilisés côté condenseurs et/ou évaporateurs des systèmes de réfrigération et pompes à chaleur.
Elle ne s’applique pas aux tuyauteries flexibles qui ne subissent qu’occasionnellement des contraintes au-delà
de la limite d’élasticité, comme par exemple lors de travaux de réparation, ou aux joints qui tournent ou
pivotent librement.
