Energy Efficiency Testing System with 2 Test Benches 6 Black Corners for Electric Rice Cookers
Overview:
This testing laboratory provides test conditions for energy efficiency testing of rices cookers, meets following standard requirements:
GB 12021.6-2008 (2017) Minimum allowable values of energy efficiency and energy efficiency grades for electric rice cookers.
Heating efficiency calculation for electric rice cookers:
Where:
η Heating efficiency, accurate to one decimal place
1.16 Constant, dimensionless
λ Correction factor. For specimen which is heated by electromagnetic induction, λ value is 1.15, which is heated by the electric heating element, λ value is 1.0; which inner pot material is non-metal product, λ value is 1.13; which inner pot material is non-metal and is heated by electromagnetic induction, λ value of 1.15.
G The amount of water before the test, unit is KG
t2 Maximum water temperature after the test, unit is Celsius (℃), accurate to one decimal place
t1 Initial water temperature before the test, unit is Celsius (℃), accurate to one decimal place
E Power consumption, unit is watt hours (W.h), accurate to two decimal places
