European foreword
This document (prEN 4855-03:2024) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 4855-03:2020.
The main changes compared to the previous edition are as follows:
— removed “Only galley chilling equipment with a freeze function will be considered” from the scope;
— removed “For this energy consumption index, only equipment with a freeze function will be
considered.” from note in 3.2;
— added measurement of the storage volume to 5.1;
— clarified test medium in 5.6;
— rewritten operational conditions to allow for units without freeze mode in 5.8;
— reduced total amount of storage capacity filled by test medium in 6.1 from 100 % of storage volume
to 30 % allowing for air to circulate between test media and provide for realistic load situation;
— swapped 6.2 and 6.3;
— clarified the definition of end of Pull-Down-Time in 6.3;
— definition of usable inner volume according to actual volume rather than number of media
insertable in 7.2;
— reestablishment of reference values required due to procedure changes;
— updated values for scaled reference kerosene consumption in 7.2;
— updated values for reference inner equipment volume and reference Pull-Down-Time in 7.3.
Introduction
During aircraft operations the food storage in the cabin is mandatory to maintain the catering on board.
There exist different equipment types to cool, freeze or chill any foods or drinks. To meet the target to
determine an energy efficiency index for galley chilling equipment (freezer, refrigerators and beverage
chillers) the purpose of this document is to standardize the test procedure and efficiency calculations
for this equipment.
1 Scope
This document specifies a test procedure to identify performance characteristics and a weight rating of
a galley chilling equipment used on aircraft. Furthermore it specifies the calculation procedure to
determine an energy consumption index and a performance index. The effect of the chilling equipment
on food quality is not addressed in this document.
