9 Fascinating Facts About the Electric Technology of Refrigerators

Refrigerators have come a long way since the first ones were created in the early 1800s. In those days, they were large and used ammonia to keep things cold. Today’s electro(électro) refrigerators are much more advanced, using electric technology to keep our food cold and fresh. There are all sorts of fascinating facts about refrigerator technology that you may not know. Here are nine of them!

Did You Know?

  1. The first refrigerators were actually used to keep food cool in the summer months? It wasn’t until 1876 that a man named Carl von Linde invented the machine that could create ice, making it possible to keep food cold all year round.
  2. Refrigerators work by using a substance called Freon. This gas is compressed and then passed through coils, which makes it expand and cool down. The Freon is then turned back into a liquid, and the cycle starts all over again.
  3. The average refrigerator has about 15 miles of electrical wiring inside of it! That’s enough to stretch from New York City to Philadelphia.
  4. Your fridge is actually one of the most energy-efficient appliances in your home. It uses about the same amount of electricity as a 100-watt light bulb.
  5. The coldest part of your fridge is actually near the bottom. That’s where the air is circulated to keep things nice and chilly.
  6. Most modern refrigerators have a built-in filter that helps to remove impurities from the water and ice you dispense. This helps to improve the taste and quality of your food and drinks.
  7. If you’ve ever wondered why there’s a little hole in the door of your fridge, it’s actually there to help equalize the pressure inside and outside the appliance. This helps to prevent moisture build-up, which can lead to freezer burn.
  8. Your refrigerator actually has its own computer system that helps it to run more efficiently. This system monitors things like the temperature inside the fridge and the amount of time the door has been open.
  9. The average lifespan of a refrigerator is about 14 years. So if your fridge is starting to show its age, you may want to start shopping for a new one soon!


We hope you found these facts about refrigerator technology fascinating! Earlier,  we mentioned that refrigerators had come a long way since the early 1800s. In just 200 years, this essential appliance has undergone a dramatic transformation. Electric refrigerators are better than ever, and make sure that you choose the perfect one for your home.
