Refrigerator Myths

There is a classic myth that the colder you let your fridge run, the faster the food inside will cool. It seems like a myth about air conditioners. But what is the truth? Let’s explore five common myths about refrigerators.

• Setting Your Fridge to a Colder Setting Cools Food Faster
  Adjusting your fridge to a colder setting doesn’t necessarily cool down your recently stored groceries any faster. It can make the compressor work harder and consume more energy. For consistent cooling, it’s best to distribute food evenly and not overload the fridge.
• Refrigerators Work by Producing Cold Air
  Actually, refrigerators work by removing the warm air inside them. They don’t “produce” cold air; they take away the heat, which in turn keeps the inside cool. It’s all about heat transfer!
• You Don’t Need to Clean Your Fridge If It’s Cold Inside
  Cold doesn’t equate to clean! Over time, food particles and spills can lead to mold or odors. Regular cleaning ensures your fridge remains sanitary and your food stays fresh.
• Food in the Freezer Can Last Indefinitely
  While freezing food significantly slows down spoilage and bacterial growth, it doesn’t stop it entirely. Over time, the quality and flavor of frozen items can degrade. It’s always a good idea to label and date frozen foods to keep track.
• Hot Food Will Spoil If You Put It Directly in the Fridge
  Actually, it’s best to cool hot foods a bit before refrigerating to prevent increasing the overall temperature inside, but you don’t need to wait until the food is at room temperature. Delaying refrigeration can increase the risk of bacterial growth. Just be mindful of not overloading the fridge with too much hot food at once.

Refrigerator FAQ

Do you know that you have to wait until you use a new fridge? This is something I never knew, and it surprised me when I read about it. Here are some of the most frequently asked questions about fridges on the internet.

• Who invented the first refrigerator?
  Jacob Perkins laid the early foundation of artificial cooling in the 1830s, but numerous pioneers contributed to the journey of the refrigerator.
• How long to wait to put food in a new fridge?
  After positioning a fresh fridge, give it 2-4 hours to settle. Post activation, ensure it runs for a few hours to stabilize its cooling before adding edibles.
• How does a refrigerator work?
  A fridge’s principle revolves around extracting warmth from its interior and expelling it externally. A sequence involving parts like the compressor and evaporator achieves this.
• How does a refrigerator ice maker work?
  An inbuilt mechanism fills a tray with water, freezes it, and upon solidification, a gentle warming element alongside a rotating gear dislodges the ice into a collection area.
• How much electricity does a refrigerator use per month?
  While consumption varies, many household fridges typically drain between 100 and 200 kWh monthly. Individual models might differ.
