l. ones manufactured for an orderer in accordance with housing dimensions, compressor freezing capacity or insulation performance specifications defined based on the orderer’s instructions, annual shipment volume of which is less than 50 units.
Energy Consumption Efficiency
[Home-use freezers]
●Categories & Target Standard Values (1)
Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in JIS C 9801 (2006).
●Categories & Target Standard Values (2)
Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in JIS C 9801-3 (2015).
[Business-use freezers ]
●Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in JIS B 8630 (2009).
Categories & Target Standard Values
In the target fiscal year and each subsequent fiscal year, for each category, the weighted average value obtained by weighting energy consumption efficiency with shipment volume shall not be above the target standard value which is a weighted average value obtained by weighting standard energy consumption efficiency*1 with shipment volume.
*1: Values obtained from the standard energy consumption efficiency calculation formulas and rounded to the nearest integers. |

(1) Freezers whose target fiscal year is FY2010 and each subsequent fiscal year (until FY2020)
Category | Standard energy consumption efficiency calculation formula | ||
---|---|---|---|
Category name | Cooling type | Rated internal volume | |
A | Cold air-natural convection type | ― | E1 = 0.844V1 + 155 |
B | Cold air-forced circulation type | Up to 300 liters | E1 = 0.774V1 + 220 |
C | Over 300 liters | E1 = 0.302V1 + 343 |
Remarks: | E1 and V1 express the following numerical values. |
E1: Standard energy consumption efficiency (unit: kWh/year) | |
V1: Adjusted internal volume It shall be a value obtained first by multiplying the rated internal volume of a freezing compartment by either 2.20 for three-star type, 1.87 for two-star type, or 1.54 for one-star type, and then rounded to the nearest integer. (unit: liter) |
