8-2 Measuring Power Consumption
Power consumption measurements of the refrigerator are measured in the Chamber, where temperature and
humidity are kept constant. In the neighboring
picture, the chamber is maintained at a
temperature of 25℃ and a humidity of 70% and
the power consumption is measured by
matching the right and left shipment notches
while the refrigerator is unloaded. Energy
consumption is calculated as follows:
There could be a discrepancy between actual
energy consumption and the energy consumption
