Heat exchangers - Air cooled liquid coolers ('dry coolers') - Test procedures for establishing the performance

This European Standard applies to remote forced convection air cooled liquid coolers, within which no change in the liquid phase occurs.
This European Standard does not apply to liquid coolers, designed primarily for installation within the machinery compartment of packaged products.
Its purpose is to establish uniform methods to test and ascertain the following:
-   Product identification;
-   Capacity;
-   Air flow rate;
-   Liquid side pressure drop;
-   Energy requirements.
This European Standard does not cover technical safety aspects.

Wärmeübertrager - Luftgekühlte Flüssigkeitskühler ('Trockenkühltürme') - Prüfverfahren zur Leistungsfeststellung

Diese Europäische Norm gilt für luftgekühlte Flüssigkeitskühler für getrennte Aufstellung, bei denen keine Änderung der Flüssigphase stattfindet.
Diese Europäische Norm gilt nicht für Flüssigkeitskühler, die hauptsächlich für den Einbau in den Maschinen-raum vorgefertigter Kältemaschinen vorgesehen sind.
Zweck ist die Festlegung einheitlicher Verfahren, um Folgendes zu prüfen und sicherzustellen:
-   Produktkennzeichnung;
-   Leistung;
-   Luftdurchfluss;
-   Druckabfall auf der Flüssigkeitsseite;
-   Energieanforderungen.
Sicherheitstechnische Gesichtspunkte sind nicht Gegenstand dieser Europäischen Norm.

Echangeurs thermiques - Refroidisseurs de liquide à convection forcée ('aéroréfrigérant sec') - Procédures d’essai pour la détermination de la performance

La présente Norme européenne s’applique aux refroidisseurs de liquide à convection forcée installés à distance, pour lesquels aucun changement de phase n’intervient dans le liquide.
La présente Norme européenne ne s’applique pas aux refroidisseurs de liquide conçus à l’origine pour être montés dans des installations complexes.
Son objet est de définir des méthodes uniformes d’essai et de contrôler des points suivants :
-   l’identification du produit ;
-   la puissance thermique ;
-   le débit d’air ;
-   la perte d’énergie mécanique côté liquide ;
-   les exigences énergétiques.
La présente Norme européenne ne traite pas des questions techniques de sécurité.

Prenosniki toplote - Zračno hlajeni hladilniki tekočin - Postopki preskušanja za ugotavljanje lastnosti

Standard EN 1048 se uporablja za zračno hlajene hladilnike tekočin s prisilno konvekcijo, znotraj katerih ne pride do spremembe tekočega stanja. Ta evropski standard se ne uporablja za hladilnike tekočin, izdelane predvsem za vgradnjo v strojni del zapakiranih izdelkov. Njegov namen je določiti enotne metode za preskušanje in določiti naslednje: – identifikacijo izdelka; – kapaciteto; – pretok zraka; – padec tlaka na strani tekočine; – energetske zahteve. Ta evropski standard ne obravnava tehničnih varnostnih vidikov.
