• 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

International standard for test procedure on define

define energy efficiency - shall take into account

realistic simulation of the actual use harmonized

international system of energy consumption

international system of energy consumption

classes including labeling scheme

SMB ： Standardization Management Board

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

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
