b. ones having a closed top face and three of the side faces composed of translucent material,
c. ones having a height of over 1,650 mm or with a total motor rated power consumption of over 300 watts, whose refrigeration unit being installed at the upper part of its main body,
d. ones that do not generate air curtain, which refers to airflow for reducing effects of surrounding temperature, etc. on the inside of the showcase (the same applies to “e”.), or that generate air curtain and have the maximum external depth dimension of 800 mm or more, among those having a closed top face and at least one of the side faces open all the time,
e. ones generating air curtain on the top and either having the average inside temperature of 15°C, being the cold air-natural convection type or having two display compartments, which refer to compartments for displaying items stored inside while keeping them cold,
f. ones manufactured for an orderer in accordance with housing dimensions, air blower, refrigerating unit or heater capacity, insulation performance, or lighting performance specifications defined based on the orderer's instructions, annual shipment volume of which is less than 10 units.
Energy Consumption Efficiency
Energy consumption efficiency shall be annual energy consumption (kWh/year) measured by a method stipulated in Appendix JA, JIS B 8631-2 (2011).
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.
