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.

Overview

EN 62552-3:2020 - published by CLC and based on IEC 62552-3:2015 - defines test methods and measurement procedures for the energy consumption and volume of household and similar refrigerating appliances. This part focuses on how to determine energy-use components (steady‑state, defrost/recovery, auxiliaries) and how to combine them into an annual energy estimate for different climates and usage patterns. The standard reflects updates for modern product configurations, electronic controls and computer-based test-room data acquisition.

Key topics and requirements

• Energy component breakdown: Energy tests are split into components (steady‑state operation, defrost & recovery, auxiliary loads) so regional authorities can apply local weightings to estimate annual consumption.
• Ambient test temperatures: Energy consumption is measured at two specified ambient temperatures - 16 °C and 32 °C - with a special 25 °C procedure for low‑noise appliances.
• No thermal mass in compartments: Tests exclude test packages/thermal mass; compartment temperatures are based on average air temperature sensors, with revised sensor positions for unfrozen compartments.
• Defrost and recovery: Detailed procedures for measuring defrost energy, representative defrost adders and correcting load‑processing tests where defrosts occur; guidance on defrost controller types (elapsed time, compressor run‑time, variable).
• Load processing efficiency test: New test to quantify the energy impact of user‑related processing (e.g., door openings, loading).
• Volume determination: Updated annexes specify methods for measuring internal volume across compartments and ice-makers.
• Wine storage appliances: New performance and energy tests added to accommodate wine storage products.
• Regional function for annual energy: Formulae and examples for assembling daily energy results into annual consumption (European regional function provided).
• Traceability & data quality: Internal checks and updated data‑collection requirements for high‑quality, reproducible energy measurements.
• Compliance links: Explicit relationship to EU ecodesign and energy labelling regulations (Reg. (EU) 2019/2019 and 2019/2016).

Practical applications

• Product development: optimize refrigeration system design, defrost strategy and control algorithms for energy efficiency.
• Compliance testing: demonstrate conformity with ecodesign and energy labelling requirements.
• Certification and type‑approval: provide standardized test data for energy labels and market surveillance.
• Comparative performance testing: enable consistent, reproducible comparisons between models and regions.
• Lab test procedures: adopt updated sensor placement, data acquisition and test-room setups.

Who uses this standard

• Appliance manufacturers and design engineers
• Accredited testing laboratories and certification bodies
• Regulatory authorities and market surveillance authorities
• Energy consultants and test‑room operators

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

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”

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 appliance.
If the run time controller is not accessible (or where it is not clear whether the controller is a run time
controller) or where the laboratory is not able to directly measure the controller operation and does not know
its run time, the value for the proxy run time shall be measured by testing as set out below. Any routine
energy tests or other tests may be used for this purpose.
Each measurement shall be undertaken over a whole defrost control cycle and tests shall be undertaken
in at least two different ambient temperatures in order to verify that it is a run time controller and to estimate
the value of t . The period selected shall comply with the following requirements:
prt
— The first defrost shall qualify as a valid defrost as specified in C.3;
— the test period shall include at least part of the subsequent defrost and recovery period that is initiated
automatically without any intervention (defrost heater on).
The estimated proxy run time of the compressor run time defrost controller for a given set of test data that
complies with these requirements is given by:
t tt+
prt, j crt,,j dh j
(25)
where
t is the estimated proxy run time of the compressor run time defrost controller for the test period
prt,j
starting with defrost and recovery period j in h;
t is the measured compressor run time in h from the initiation of defrost heater operation for
crt,j
defrost and recovery period j to the initiation of defrost heater operation for the subsequent
defrost and recovery period j + 1;
t is the time from the start of the defrost heater on until the compressor restarts in h during
dh,j
defrost and recovery period j where the timer advances during the heater operation;
otherwise a value of zero if the timer does not advance during the heater operation.
A common configuration is that the defrost heater is allocated a fixed maximum time of operation in the
timer defrost controller (for example 20 min). The actual heater on time will vary depending on the frost load
for the specific defrost. So the time between the heater off and the compressor on may vary, but the total
time from heater on to compressor on should be constant in this configuration. Where the laboratory has
any doubt about the appliance configuration, it is assumed that the defrost timer does not advance when
the defrost heater is on, so that only compressor on time is counted and the value of t is set to zero in
dhj
Formula (25).
Additional routine tests undertaken at other ambient temperatures and/or temperature control settings,
including user related loads such as door openings and small processing loads should be reviewed to
assess defrosting behaviour. The observed defrost interval should be consistent with the measured proxy
run time, otherwise it shall be classified as a variable defrost controller.
NOTE 2 These tests can be used to detect whether the run time controller is over-ridden by some other control
mechanism during normal use conditions.
To qualify as a compressor run time defrost controller, the coefficient of variation (standard deviation divided
by the mean) of the measured values for either compressor proxy run time t or compressor run time alone
prt,j
t shall be less than 5 % for the defrost intervals examined. Where the product does not comply with this
crt,j
requirement, it shall be classified as a variable defrost controller. The value of t used in subsequent
prt
calculations shall be the average of all measured values of t .
prt,j
Once confirmed, the proxy run time can be used to calculate the actual defrost interval (in elapsed time)
for any temperature control setting, ambient temperature and load processing condition, as a function
of the compressor run time. For all refrigerating appliances with compressor run time defrost controllers,
the percentage run time shall be reported for steady-state conditions in Annex B and the extra compressor
run time (in h) shall be calculated for defrost and recovery periods (in Annex C, Formula (21). The defrost
interval for each test condition and temperature control setting is given by:
tt−∆
prt dr t −∆t
crt dr
t
df
CRt CRt
SS SS
(26)
where
==
=
t is the estimated defrost interval (elapsed time) for each temperature control setting and
df
ambient temperature under test in h, including the impact of defrost and recovery
t is the representative measured proxy run time of the compressor run time defrost controller
prt
(in h) in accordance with Formula (25)
CRt is the compressor run time (as a percentage) during the steady-state operation for each
SS
temperature control setting and ambient temperature under test as determined in B.3.3
or B.4.3
Δt is the representative incremental compressor run time (in hours) for defrost and recovery
dr
in accordance with C.5 in accordance with Formula (25)
t is the representative time from the start of the defrost heater on until the compressor restarts
dh
in h during a defrost and recovery period where the timer advances during the heater
operation, otherwise a value of zero
t
crt is the representative compressor run time in h from the initiation of one defrost heater
operation until the initiation of the next defrost heater operation (this can be determined from
rearranging Formula (25).
NOTE Z1 The exclusion of heater on time t and t is the default assumption for calculations in Formula (25) and
dh,j dh
Formula (26). If the defrost timer does not advance during the defrost heater operation or if the laboratory is unsure,
then the value of tdh,j and tdh is set to be zero for both equations. It is essential to apply consistently heater on time tdh,j
and t in Formula (25) and Formula (26)."
dh
In D.4.2, "Variable defrost controllers – declared defrost intervals", replace the first bullet of third paragraph
with:
"— Δt shall not exceed 12 h at an ambient temperature of 32 °C (elapsed time)."

13 Addition of Annex ZA, “Chill compartment temperature control test”
Add the following Annex ZA:
"
Annex ZA
(normative)
Chill compartment temperature control test
A chill compartment shall be able to control its average temperature within a certain range without user-
adjustments of its control. This shall be checked during a set of temperature control tests which consists of
two parts: reference tests at 32 °C and verification tests at 16 °C. All temperature control tests shall be
performed as prescribed for the energy consumption tests. The controller setting of the chill compartment,
if present, shall be the same for all temperature control tests.
Note Z1 In general all or part of the temperature control tests can also be used for the energy consumption
determination.
Determine the reference chill compartment temperature T by performing one or more reference tests
ccma,ref
at 32 °C ambient. T is the interpolated value of T according Annex E and all reference tests shall be
ccma,ref ccma
valid tests for interpolation subject to the following conditions:
a) If the temperature control of the chill compartment is not adjustable by the user, the chill compartment
is tested in the condition as delivered.
b) If the temperature control of the chill compartment is accessible to the user (e.g. visible control on the
display or by following manufacturer instructions), it is set to a position which leads to an interpolated
temperature of T at or as close as possible below the target temperature (+2 °C) .
ccma
The interpolation can be to the target temperature(s) of any controlled compartment present, with the
exception of the chill compartment as the controller setting shall be the same for each reference test.
Perform one or more verification tests at 16 °C ambient temperature with the same temperature control
setting of the chill compartment as applied at 32 °C. Other control settings shall be such that the controlled
compartments are within 4 K of their target temperature, with the exception of the fresh food compartment,
where, if present, the fresh food compartment temperature T shall be in the range from 2 °C to 6 °C.
ma
For each of these verification tests, T shall be within T ± 1,5 K. An example of a temperature control
ccma ccma,ref
diagram is given in Figure Z1. In case any of the verification tests is not complying with this requirement,
the compartment shall not be classified as a chill compartment.
It is allowed to perform the reference tests for determining T at 16 °C ambient temperature and perform
ccma,ref
the verification tests at 32 °C.
