Power consumption is "larger" refrigerator nameplate ratings are false?

Many consumers for refrigerator nameplate on tagging in consumption, doubt, that there is a refrigerator electricity consumption is a phenomenon with xubiao, indeed some consumers have been tested, some refrigerator electricity consumption is very large, more than a nameplate on callout numbers, this is why?

First, the user of the ambient temperature is much higher than 25 ° c.

The ambient temperature is higher, the outside heat conduction on refrigerator box, convection, radiation, the faster the temperature inside the tank goes faster, that would require the work to the fridge would lower the temperature, thus working time in the fridge too long, the corresponding power consumption increases. In contrast, the power consumption of the refrigerator in the summer, in winter the high power consumption low.

Second, users in the measurement process is often switch, and the door is closed, and these factors will enable the internal temperature rise in the fridge, resulting in increased working hours in the fridge, so power consumption is increasing.

Third, the user is used to measure the power consumption of electricity meters have a precision, the measured results exist certain error, for example: users of electricity meters accuracy is 1.5 or 5.0, then test results for test of error and multiply by 1.5% or 5.0%.

Fourth, the user of the food in the refrigerator, can also cause relatively long working hours in the fridge, start stop number, because the food in the refrigerator to cool for role in curbing the rise in temperature in the fridge.

Refrigerator in the factory are done professional testing, so we do not recommend that users in the non-professional conditions own measuring the power consumption of the fridge.
