Household refrigerating appliances - Characteristics and test methods - Part 3: Energy consumption and volume

IEC 62552-3:2015 specifies the essential characteristics of household and similar refrigerating appliances cooled by internal natural convection or forced air circulation, and establishes test methods for checking these characteristics. This part of IEC 62552 describes the methods for the determination of energy consumption characteristics and defines how these can be assembled to estimate energy consumption under different usage and climate conditions. This part of IEC 62552 also defines the determination of volume. - All parts of the standard have been largely rewritten and updated to cope with new testing requirements, new product configurations, the advent of electronic product controls and computer based test-room data collection and processing equipment. - For more efficient analysis and to better characterise the key product characteristics under different operating conditions, the test data from many of the energy tests in Part 3 (this part) is now split into components (such as steady state operation and defrost and recovery). The approach to determination of energy consumption has been completely revised, with many internal checks now included to ensure that data complying with the requirements of the standard is as accurate as possible and of high quality. - Part 3 (this part) now provides a method to quantify each of the relevant energy components and approaches on how these can be combined to estimate energy under different conditions on the expectation that different regions will select components and weightings that are most applicable when setting both their local performance and energy efficiency criteria while using a single set of global test measurements. - For energy consumption measurements in Part 3 (this part), no thermal mass (test packages) is included in any compartment and compartment temperatures are based on the average of air temperature sensors (compared to the temperature in the warmest test package). There are also significant differences in the position of temperature sensors in unfrozen compartments. - The energy consumption test in Part 3 (this part) now has two specified ambient temperatures (16°C and 32°C). - A load processing energy efficiency test has been added in Part 3 (this part). - Tests (both performance (Part 2) and energy (Part 3 (this part)) have been added for wine storage appliances.

Appareils de réfrigération à usage ménager - Caractéristiques et méthodes d'essai - Partie 3: Consommation d'énergie et volume

L'IEC 62552-3:2015 spécifie les caractéristiques essentielles des appareils de réfrigération à usage ménager et similaires, refroidis par convection naturelle interne ou par circulation d'air forcé, et établit les méthodes d'essai pour la vérification de ces caractéristiques. La présente partie de l'IEC 62552 décrit les méthodes de détermination des caractéristiques de consommation d'énergie et définit comment elles peuvent être assemblées pour estimer la consommation d'énergie dans différentes conditions d'utilisation et climatiques. La présente partie de l'IEC 62552 définit également la détermination du volume. Les normes IEC 62552-1, IEC 62552-2 et IEC 62552-3 annulent et remplacent la première édition de l'IEC 62552 publiée en 2007. Les normes IEC 62552-1, IEC 62552-2 et IEC 62552 3 constituent ensemble une révision technique et incluent les modifications techniques majeures suivantes apportées à l'IEC 62552:2007: - Toutes les parties de la norme ont été largement réécrites et mises à jour pour tenir compte des nouvelles exigences d'essai, des nouvelles configurations du produit, de l'apparition de nouvelles commandes de produit électronique et d'équipements informatiques de collecte et de traitement de données de salle d'essai. - La Partie 3 (la présente partie) fournit désormais une méthode permettant de quantifier chacune des composantes énergétiques pertinentes, ainsi que les approches permettant de les combiner pour évaluer l'énergie dans différentes conditions, en partant du principe que les différentes régions vont choisir les composantes et pondérations les plus applicables lors de l'établissement des critères de performances et d'efficacité énergétique tout en utilisant un seul ensemble de mesures d'essai globales. - Pour les mesures de la consommation d'énergie dans la Partie 3 (la présente partie), aucune masse thermique (paquets d'essai) n'est incluse dans un compartiment, les températures de compartiment reposant sur la moyenne des capteurs de température de l'air (comparée à la température du paquet d'essai le plus chaud). La position des capteurs de température dans les compartiments non congelés présente également des différences importantes. - L'essai de consommation d'énergie dans la Partie 3 (la présente partie) s'appuie désormais sur deux températures ambiantes spécifiées (16 °C et 32 °C). - Un essai d'efficacité d'énergie de traitement de charge a été ajouté dans la Partie 3 (la présente partie). - Un essai d'efficacité d'énergie de fabrication de glace du type à réservoir a été ajouté dans la Partie 3 (la présente partie). - Les méthodes de mesure de la surface et du volume de stockage des étagères ne sont plus incluses. Dans la Partie 3 (la présente partie) la mesure du volume a été révisée pour donner le volume interne total avec uniquement les composants nécessaires au bon fonctionnement du système de réfrigération considéré comme étant en place. - Des essais (de performances (Partie 2) et d'énergie (Partie 3 (la présente partie)) ont été ajoutés pour les appareils de stockage du vin.

Endorsement notice
The text of IEC 62552-3:2015 was approved by CENELEC as a European Standard with agreed common
modifications.
1 Modification to the Introduction
Add the following paragraph:
"This standard was developed in relationship with Regulations (EU) 2019/2016 of 11.3.2019 on energy
labelling and (EU) 2019/2019 of 1.10.2019 on ecodesign for refrigerating appliances."
2 Modification to Clause 3, "Terms, definitions and symbols"
Add the following definition:
"3.1.Z1
low noise refrigerator
refrigerating appliance without vapour compression and with airborne acoustical noise emission lower than
27 A-weighted decibel referred to 1 pico Watt [dB(A) re 1 pW]"
3 Modification to Clause 5, "Target temperatures for energy determination"
Add the following subclause:
"5.Z1 Controllability of temperatures in a compartment
The standard does generally not include tests for the controllability of temperatures in a compartment (i.e.
how well the temperature is kept constant during changing environmental conditions without the user having
to adjust temperature control settings). The exception is the chill compartment for which a chill compartment
temperature control test has been included in Annex ZA."
4 Modifications to Clause 6, "Determination of energy consumption"
In 6.8.5, "Total energy consumption", delete the sentence "E expressed as an integrated energy value
aux
over a year".
Replace the seventh and eighth paragraph and Formula (4) with:
"The total annual energy consumption of a refrigerating appliance E (except for low noise refrigerating
total
appliances) can be given by:
E fE E+ E
{ }
total daily16°C , daily32°C aux
(4)
where
f is a regional function to give the annual energy based on daily energy at 16 °C and 32 °C. In
this standard this function is defined as:
f{E , E } = ( Day × E ) + (Day × E )
daily16°C daily32°C 16°C Daily16°C 32°C Daily32°C
where Day = Day = 365/2 days = 182,5 days;
16°C 32°C
see Annex I for examples by taking into account D = D = 365/2 d = 182,5 days;
16°C 32°C
E
aux is the annual energy from ambient controlled anti-condensation heater(s) as described in
Annex F. See I.5 for an example how to calculate this auxiliary.
The E shall be calculated in according the following equation:
total
E= 182,5× E +×182,5 EE+
total daily16°°C daily32 C aux
For low noise refrigerating appliances, the energy consumption shall be determined as provided for in
Formula 4, but at an ambient temperature of 25 °C instead of at 16 °C and 32 °C.
=
E , expressed in kWh/24h and rounded to three decimal places for the calculation of the AE is then as
daily
follows:
E = E25
daily
where E25 is E at an ambient temperature of 25 °C and derived by interpolation of the energy tests at the
T
target temperatures listed in Table 1."
5 Modification to Annex A, “Set up for Energy testing”
Replace the first paragraph of A.2.6.5, "Position of the temperature sensor in automatic ice-makers" with:
"An automatic ice-maker bin shall have a single temperature sensor located in the position specified as
follows for all energy tests:"

Δt is the additional compressor run time in h as determined in accordance with C.3.3 for
drj
the defrost and recovery period j commencing at the end of period X"
7 Modifications to Annex C, “Defrost and recovery energy and temperature
change”
In C.3.3, "Case DF1 calculation of values" add the following after the NOTE:
"During a load processing efficiency test, it is possible that one or more defrosts occur for which a
correction shall be made. This correction is based on splitting the defrost and recovery energy in a fixed
part and the energy used by the defrost heater:
Fixed defrost adder is:

E is the energy used by the defrost heater during the defrost and recovery period j in Wh."
df-adder,j
In C.4, "Number of valid defrost and recovery periods", add the following note at the end:
"NOTE Z1 The defrost heater energy ΔEdf-adder,j and incremental defrost and recovery energy ΔEdf,i for new appliances
and appliances that have not been operated for some time could be initially low until the defrost heater energy stabilizes."
In C.5, "Calculation of representative defrost energy and temperature", replace Formula 22 with:

8 Modifications to Annex D, “Defrost interval”
In D.2, "Elapsed time defrost controllers", replace Note 2 with:
"NOTE 2 The same timers could be used as compressor run time controllers or as elapsed time controllers,
depending on how they are configured in the refrigerating appliance."
Replace the entire subclause of D.3, "Compressor run time defrost controllers" with:
"For these controllers, the defrost interval is defined by the compressor run time (or on time in hours) (or
in some cases the compressor run time plus the maximum time allocated for defrost heater operation).
These controllers are only applicable to single speed compressors. The defrost interval is therefore
approximately inversely proportional to the total heat load on the refrigeration system (ambient
temperature and user loads plus any internal heat loads). The most common defrost run time controllers
range from 6 h to 12 h of compressor run time. Typically this would result in defrost intervals of the order
of 12 h to 30 h (elapsed time) at elevated ambient temperatures and somewhat longer defrost intervals
at lower ambient temperatures.
NOTE 1 The same timers could be used as compressor run time controllers or as elapsed time controllers,
depending on how they are configured in the refrigerating app
