• Direct cool type is IEC62552 harmonized, but there are many countries no using the latest standard
• Forced cool type, there is no harmonized test method and each
The refrigerator energy efficiency has not been harmonized in the world.
yp ,country use its own standard
• Only Japan use the standard which reflect actual usage
• It is not possible to evaluate the refrigerator energy saving performance and technology
Many energy labels for energy saving performance
EU China JapanUS Australia Korea India
Many energy labels for energy saving performance

Problem in developing economies on refrigerator performance international standard
Refrigerator performance international standard does not
take products in the developing economies into account
• Standard has been developed in Europe
• Not taken into account different culture, climate, etc
• Products produced in developing economies do not conform to the latest international standards
IEC activities are not active in developing economies
IEC activities are not active in developing economies
• Participants in IEC meeting from developing economies are not enough
• Without proposal from developing economies, Europe will keep the present status
• Need more participants to be balanced with Europe

OLD STORY IN JAPAN
1979 JIS C9607 Two ambient temperatures

1993 JIS C9607 One ambient temperature
No door openings
No ice make Harmonizedwith ISO, discrepancy 100% i 1998
JP announced to ratify the WTO-TBT agreement in 1994
100% in 1998
1999 JIS C9801 One ambient temperature
Door openings No ice make Discrepancy 200% in 2004
2006 JIS C9801 Two ambient temperatures
Door openings and load input
Ice make No discrepancy with actual use
Example of Test Results
Units : kWh/year
More than 3 times maximum, old JIS marked value against actual,
now new JIS value is very similar to actual value

Concept of proposed method
• The method is to make only once door open and put
6. Proposed IEC amendment on energy consumption test method
The method is to make only once door open, and put
the water load in so that the frost accumulation to the
evaporator has been created
• The present test method of stable and defrost has
been unchanged but the test of load input has been
been unchanged, but the test of load input has been
added. By this method any kind of refrigerators in the
world can be evaluated

Survey of actual use of refrigerator
• 18 location in Japan, one year surveyed actual use
• Ambient temperature, inner temperature, energy consumption door open/close ice making were measuredconsumption, door open/close, ice making were measured
instrument
Suggestion : Each country had better make survey like this for determination of factor "a”
12
• SC59M agreed to revise energy consumption test method
• Consists of three parts but publish as one contains three parts
• Pay attention to energy consumption and other performance test
IEC TC59/SC59M results and future plan
Pay attention to energy consumption and other performance test
IEC62552 Part1 definition and test conditions

Try to make refrigerator performance international standard amendment to be fair and correct
• To evaluate forced convention type refrigerator correctly
7. Future problems and proposal
• Take into account actual use for energy consumption test method
• Consider the amendment taken into account different conditions, such as climate, actual usage, etc
More participants into IEC activity from developing economies• Increase the chance of participants from developing economies• Improve the ability to make proposal to solve problems
• More participants to be balanced with Europe
Participants will develop their certification scheme;
In a summary, what would emerge from the Project are:
8. ERIA Project on Refrigerator
& proposed Policy Recommendation
- test laboratories’ testing capability up, - national committees’ discussion capability up on latest
standards’, - regulators’ implementation capability up of the high level
standards
By adaptation of the standards which reflect actual usage, the
countries participated can contribute to the reduction of CO2
By extension to the product safety, the un-safe products will be wiped out from the markets
15
Each economy shall recognize that the introduction of energy labeling scheme in the wide range of the electrical appliances would contribute to the reduction of CO2
Review of current refrigerator energy standard and labeling scheme shall be conducted in each economy to confirm that they reflect
Expected Policy Recommendation
shall be conducted in each economy to confirm that they reflect actual energy consumption at home
Each economy shall recognize that the all the IEC standards have been developing rapidly and it is recommendable to use the latest standards to avoid the technical barriers in trade
Review of current participating situation in IEC activities shall be conducted in each economy to confirm that if any inconvenience might happen to the existing electrical appliances by the recent
g pp g pp ydevelopment of the standards. Each economy shall join the IEC activities of household appliance performance standards in order to reflect the economy’s common features, technologies and usages
After each economy become capable to conduct household appliance performance testing independently, try to establish the common household appliance energy labeling in the future
The progress of the IEC standardization on household refrigerating appliances
