Despite the latest technology, one counts refrigerator still one of the largest consumers of electricity in the home today. One reason for this, of course, is that the refrigerator is constantly cooling down food. Every time the refrigerator door is opened, warmer room air enters the interior. This then has to be cooled down again, which ultimately increases power consumption. It is therefore advisable to calculate the energy consumption of household appliances.

How to calculate the power consumption of your refrigerator

  • In the advertising of refrigerators, an electricity consumption per year is often stated. You can safely forget this information. In the small print it is usually also stated that the actual energy consumption depends on the use of the refrigerator.
  • In order to calculate the actual power consumption, you must find out about the power consumption of the device on the type plate of your refrigerator. There you will find information about 120 W. This means that the refrigerator has a power consumption of 0.12 KW / h in one hour.
  • Now it is the case that the cooling unit is not permanently in operation. As a rule, the cooling compressor only runs for a few minutes in the refrigerator and then switches off again. Of course, no energy is consumed when the unit is not running.
  • Therefore, you would theoretically have to use a stopwatch to stop the times when the compressor in the refrigerator is running. You would have to do this over several hours. Then you know exactly how many minutes the refrigerator has used electricity within a few hours.
    • Reduce power consumption in the refrigerator - this is how it works

    The refrigerator is in operation day and night, around the clock. If your fridge ...

  • Since it is a rather cumbersome proposition, it is much easier to calculate power consumption with a power meter. These devices you can get it for a few euros in any hardware store and sometimes even in discount grocery stores.
  • You pull the plug of the refrigerator out of the socket and plug in the power consumption meter. Then plug the refrigerator's mains plug into the socket of the measuring device.
  • After a day you can see how much electricity the refrigerator has consumed within 24 hours.
