3 1. Global demand of refrigerators and Problems of Global performance standards 2008~2009 by world economic crisis, the demand decreased but Asia ratio became the largest Global demand of refrigerator ( M unit ) Demand Output Demand and output, area ratio ( 2007 ) NA EU JP CN Asia, others 14% 5% 31% % NA EU JP CN Asia, others 10% % 20% 40% 60% 80% 100% The refrigerator energy efficiency has not been harmonized in the world. 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 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 US Japan Australia Korea India 2

4 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 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 2. Japanese proposal to IEC on energy consumption test method Two ambient temperature, door open once and put water load in IEC (2007) ISO (2005) Japan proposal at Munich Proposal (2008) AS/NZS (1997) AHAMHRF-1 (2004) KS C9305 (1999) CNS 2062 (1995) CNS 9577 (1989) JIS C 9801 (2006) Ambient temperature 25 or 32 C 16 & 32 C 32 C 32.2 C 30 C 15 & 30 C Target tem perature Fresh food C +4 C +4 C +3 C +7.2 C +3 C +4 C Freezer * -6 C -6 C -9 C -9.4 C -6 C Freezer ** -12 C -12 C -15 C -15 C -12/-15 C -12 C Freezer *** -18 C -18 C -18 C -18 C Load input Test package (solid) *Water load No load No load No load Test package, pet bottle Door open/close None Yes None None None Yes *Water load became option at Kyoto meeting 3

Discrepancy problem on energy consumption value in Japan Target of energy consumption and improvement results - top runner - OLD STORY IN JAPAN Labeled value has achieved a lot more than the target value Average en nergy consumption (k kwh/year) Source: METI Average energy consumption weighted by the labeled value % % Actual Target Actual Actual Target Actual Refrigerator and Freezer Refrigerator-freezer 5

7 Discrepancy between labelled value and actual use value OLD STORY IN JAPAN Consumer organization made tests at actual used home Several times more tested value obtained against labeled value mption (kwh/year) energy consu Actual use Labeled value -JIS- A1 A2 A3 A4 A5 A6 Existing Survey A (JCA, July 2004) Source: METI Refrigerator total energy consumption has not been correct OLD STORY IN JAPAN All Japan refrigerator energy consumption was mistaken; 2004 about 1.3TWh estimated, but actually nearly doubled, 2.8TWh Total energy con nsumption (TWh) Total energy consumption by year Actual use estimated Labeled value calculated-jis TWh = Wh Produced 旧 JIS according での設計 to Old JIS Dish wash/ dry 1.6% Cloth dryer 2.8% House power use, CO2 emission results Electric toilet 3.9% Electric carpet 4.3% Others 20.2% TV 9.9% Air conditioner 25.2% Mt-CO2 Refrigerator 16.2% Light 16.1% 130% 6

Development of energy consumption test method which reflects actual usage JIS C 9801 revised- OLD STORY IN JAPAN 1979 JIS C9607 Two ambient temperatures Door openings No ice make Not harmonized with ISO JP announced to ratify the WTO-TBT agreement in JIS C9607 One ambient temperature 1999 JIS C9801 One ambient temperature No door openings No ice make Harmonized with ISO, discrepancy 100% in 1998 Door openings No ice make Discrepancy 200% in JIS C9801 Two ambient temperatures Door openings and load input Ice make No discrepancy with actual use Example of Test Results More than 3 times maximum, old JIS marked value against actual, now new JIS value is very similar to actual value Units : kwh/year Manufacturers A B C D Number of doors/ capacity 3 doors/ 384 liters 4 doors/ 357 liters 5 doors/ 457 liters 4 doors/ 425 liters Inverter None None Equipped Equipped Old JIS indicated values Actual measurement values Revised JIS measurement values

Proposed IEC amendment on energy consumption test method Concept of proposed 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 added. By this method any kind of refrigerators in the world can be evaluated 10

12 Load input : none Water load input Door open/close 1 minute Load input : yes P GLOBAL = P 1 + P 2 + a x delta P 4 hours after defrost heater OFF Freezer temperature delta P = P 3 -P 1 P 1 P 2 P 3 Average freezer temperature Operated condition Load input P 1 Stable no P 2 Pre-cool, defrost, recovery no P 3 Load input, temperature recovery yes Direct cool P IEC =P 1 Same test t method as present Forced cool P IEC =P 1 + P 2 IEC62552 Direct cool P GLOBAL =P 1 + a x(p 3 -P 1 ) Forced cool P GLOBAL = P 1 + P 2 +a x(p 3 -P 1 ) Load input test method which reflect actual use a: variable by each country 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 measured Suggestion : Each country had better make survey like this for determination of factor "a instrument 11

15 7. Future problems and proposal Try to make refrigerator performance international standard amendment to be fair and correct To evaluate forced convention type refrigerator correctly 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 8. ERIA Project on Refrigerator In a summary, & proposed what would Policy emerge Recommendation from the Project are: Participants will develop their certification scheme; - 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 14

16 Expected Policy Recommendation 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 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 development 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 Thank you Hiroshi Sasaki Jun Nakamura JEMA 15
