Walk-in cold rooms - Definition, thermal insulation performance and test methods - Part 1: Prefabricated cold room kits
This European Standard applies to prefabricated walk-in cold room kits and components. It provides test or calculation methods to assess thermal insulation performances under normal end-use conditions.
Performance characteristics of walk-in cold rooms are to be assessed in terms of thermal insulating properties, in order to give a basis on which assessing energy consumption related properties of walk-in cold rooms, and of their components.
Performance characteristics are to be assessed for every single component of the walk-in cold room, and for the assembled walk-in cold room as a whole.
The normal end-use conditions of a walk-in cold room are considered to be:
- installation inside an existing building;
- not exposed to external weather conditions.
Begehbare Kühlräume - Begriffe, Wärmedämmleistung und Prüfverfahren - Teil 1: Fertigbauteile für Kühlräume
Diese Europäische Norm ist anwendbar auf vorgefertigte Bausätze und Bauteile von begehbaren Kühlräumen. Sie legt Prüf- oder Berechnungsverfahren zur Bewertung des Wärmedämmverhaltens unter normalen Bedingungen der Endnutzung fest.
Um eine Grundlage für die Bewertung der energieverbrauchsrelevanten Eigenschaften von begehbaren Kühlräumen und deren Bauteilen zu schaffen, sind die Leistungskenngrößen von begehbaren Kühlräumen hinsichtlich ihrer wärmedämmenden Eigenschaften zu bewerten.
Bewertet werden die Leistungskenngrößen für jedes einzelne Bauteil des begehbaren Kühlraumes sowie Leistungskenngrößen des begehbaren Kühlraumes als Ganzes.
Als normale Umgebungsbedingungen der praktischen Anwendung eines begehbaren Kühlraumes sind zu berücksichtigen:
- Aufstellung innerhalb eines vorhandenen Gebäudes;
- der Kühlraum ist nicht den äußeren Wetterbedingungen ausgesetzt.
Chambres froides - Définition, performances d’isolation thermique et méthodes d’essai - Partie 1 : Kits de chambres froides préfabriquées
La présente Norme européenne s’applique aux kits de chambres froides préfabriquées et à leurs composants. Elle fournit des méthodes d’essai ou de calcul pour évaluer les performances d’isolation thermique dans les conditions normales d’utilisation finale.
Les caractéristiques de performance des chambres froides sont à déterminer en termes de propriétés d’isolation thermique, afin de fournir une base sur laquelle évaluer les propriétés liées à la consommation d’énergie des chambres froides et de leurs composants.
Les caractéristiques de performance sont à évaluer pour chaque composant individuel de la chambre froide et pour la chambre froide assemblée dans son ensemble.
Les conditions normales d’utilisation finales d’une chambre froide sont :
- l’installation à l’intérieur d’un immeuble existant ;
- non exposée aux conditions climatiques extérieures.
Dostopne hladilnice - Definicije, toplotnoizolacijske lastnosti in preskusne metode - 1. del: Montažne hladilnice
Ta evropski standard se uporablja za montažne dostopne hladilnice in njihove sestavne dele. Določa preskusne ali računske metode za oceno učinkovitosti toplotne izolacije.
Učinkovitost dostopnih hladilnic se ocenjuje na osnovi lastnosti toplotne izolacije, ki so podlaga za ugotavljanje lastnosti, povezanih s porabo energije v dostopnih hladilnicah in njihovih sestavnih delih.
Ocenjuje se učinkovitost za vsak posamezni del dostopne hladilnice in za montirano dostopno hladilnico kot celoto.
Ta evropski standard vsebuje tudi navodila za namestitev.

Introduction
The drafting of this European Standard was driven by the necessity to compare the systems placed on
the market on the base of the minimum thermal insulation requirements and to establish the average
level of energy consumption for a future minimum energy performance standard definition, with
reference to the EU policy on increasing energy efficiency of energy related products (Directive
2009/125/EC) in the frame of the EU “20-20-20” targets. It also aims to identify the reference standards
for calculation, measurement of insulation properties, to identify the best practice rules for elimination
of thermal bridges, assembly techniques and provisions to be taken in order to ensure the best level of
insulation and power consumption.
