In ancient times, in India, Egypt, Greece, and Rome, the wealthy citizens used snow cellars into the ground to keep the ice transported from mountains that could be stored for several months. It is from where the idea of Refrigerators can be traced!
Let us go behind the story of modern-day refrigerators:
1. The main reason for having a refrigerator is to “cool-down” the food. Cold temperatures help food stay fresh longer, thus preserving it.
2. The idea behind refrigeration is to prevent bacteria from nomming on your food. The aim is to stop the decomposition of food.
3. The idea for the refrigerator had come from an American inventor, Oliver Evans.
4. Jacob Perkins is known as the Father of Refrigerator who worked with Evans. He also received a patent for a vapour-compression cycle (using liquid ammonia in 1835) with the title: Apparatus and Means for Producing Ice, and in Cooling Fluids.
5. Nonetheless, the first commercially successful domestic refrigerator was presented in late 1916 by the Kelvinator Company of Detroit, now owned by Electrolux.
6. Do you know, October 30th is celebrated as a Haunted Refrigerator Night!
8. The largest refrigeration unit in the world is the Hadron Collider which is 27-kilometers long and uses 9300-magnets. Also, over 10,000 tonnes of liquid nitrogen for cooling is used in this Collider.
9. One of the most expensive fridges in the market is La Cambusa by an Italian Brand, Meneghini. The fridge costs more than $45,000!
We have come a long way since the traditional icebox. Today, you have a variety of choices for refrigerators. Regardless of what we have, one thing remains the same: “for them to last, we need to take care of them.”
