One of the biggest energy expenses in our apartment is our refrigerator. Unlike the router and other electronics, we never unplug our fridge. Although some people go fridge-less, I will just minimize the energy used by our fridge. In order to do this, I looked up the correct temperature settings for a fridge and freezer.
I measured the temp in my fridge and found that it varied between 33 – 38 degrees F based on where the thermometer was located. The sources say that anywhere between 32-40 degrees is acceptable, so I will not make any changes to my fridge. Now for the freezer: multiple sources recommended 0 degrees F and a few sources even said up to 3 degrees was fine. Our freezer was at -2. Therefore, I happily went to look at the temperature controls. Hmmm. Now I had a problem. There’s only 1 temperature knob for the whole thing! No separate knobs for the fridge/ freezer. What kind of engineer designed that?
Since the temperature change was a flop, I also decided to follow a few other tips to make my fridge more efficient: Keep the fridge and freezer pretty full so cold air is retained when the door is opened, but still leave room for air flow. Also, I dusted the condenser coils on the back of the fridge. If those are clean, they will be most efficient at exchanging heat with the surrounding air. Even though I wasn’t able to save energy with my freezer, at least I know that my fridge is the proper temp and I’m following a few other tips to use less energy.
