CEN/TC 44/WG 4 - Walk-in cold rooms

This document provides test or calculation methods to assess thermal insulation performances for customized walk-in cold rooms and components under normal end-use conditions.
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;
- internal side of panels subject to temperatures within the indicative range −40 °C ≤ T ≤ 12 °C;
- external side of panels subject to temperatures within the indicative range −8 °C ≤ T ≤ 30 °C; temperatures below 0 °C, or higher than 20 °C, can be reached if the walk-in cold room is located inside not air-conditioned premises.
NOTE In case the customized walk-in cold room working at positive storage temperature is used as a food processing room or a clean room, the standard is applied.

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.
