11. Electric Freezers

1) Target Scope:

Electric freezers stipulated under JISC9801, which use thermo-elements, produced for industrial use, and absorption types are excluded.

2) Energy Consumption Efficiency:

Energy consumption efficiency is annual power consumption (kWh/year) measured as specified in JIS C9801 15, power consumption tests.

3) Category and Target Values:

Category	Standard energy consumption efficiency calculation formula
Natural convection type	E = 0.281V + 353
Forced circulation type	E = 0.281V + 353

Remarks:

E and V express the following numerical values:
E: Standard energy consumption efficiency (unit: kWh/year)
V: Adjusted internal volume (the figure acquired first by multiplying rated internal volume of the freezer by either 2.15 for three-star type freezers, 1.85 for two-star type freezers, or 1.55 for one-star type freezers, and then by adding the result to rated internal storage volume for other than freezers) (unit: liter)

4) Target Fiscal Year:

2004

5) Energy Conservation Effects:

Approximately 30% improvement in efficiency compared to 1998 levels by 2004.

6) Display Items:

Product name and type, rated internal volume, energy consumption efficiency, frame dimensions, manufacturer's name, product body

7) Place of Display:

Manufacturers or importers that manufacture or import fewer than 2,000 electric refrigerators and fewer than 300 freezers in total are excluded.
