The word refrigerator comes from the Latin word for “cold,” frigus.
A refrigerator is a household appliance that consists of a thermally insulated compartment and a heat pump ( either mechanical or chemical) that transfers heat from the inside of the fridge to its outside environment so as to keep the inside of the fridge cool. The name “refrigerator” is derived from the Latin verb refrigero which means “to cool, to refresh”.
Why Was The Refrigerator Invented?
The refrigerator was invented to keep food fresh.
In 1834, an American inventor named Jacob Perkins was issued a British patent for a vapor-compression refrigeration system. This was the first time that a machine had been used to create ice artificially. It wasn’t until 1876, however, that the first practical refrigerator was invented.
In 1876, an American inventor named Alexander Twinning was issued a patent for a ice-making machine. This machine used a vapor-compression refrigeration system to create ice. It wasn’t until 1884, however, that the first practical refrigerator was invented.
In 1884, an American inventor named John Gorrie was issued a patent for a ice-making machine. This machine used a vapor-compression refrigeration system to create ice. It was the first machine to use this type of refrigeration system.
How Does A Refrigerator Work?
A refrigerator works by using a compressor to cool the air inside.
A refrigerator
Is one of the most important appliances in your home. It keeps your food cold and your drinks refreshing. But have you ever wondered how does a refrigerator work?
The basic principle behind a refrigerator is that it removes heat from the air inside the fridge and transfers it to the air outside. This process is known as heat transfer.
Inside your fridge, there is a closed loop system of Freon gas. This gas is compressed and then expands, which causes it to absorb heat from the air inside the fridge. The Freon then travels to the coils on the back of the fridge, where it releases the heat to the air outside.
This process is repeated over and over again, and it is the reason why your food stays cold and your drinks remain refreshing.
Now that you know the basics of how a refrigerator works, let’s take a look at a real-life example.
Imagine that you have a can of soda in your fridge. The can is cold because the air inside the fridge is cold. The Freon gas inside the fridge is constantly removing heat from the air and transferring it to the outside air.
Now, imagine that you open the door of the fridge. The cold air inside the fridge starts to escape and the warmer air from outside starts to enter.
At this point, the Freon gas is not able to remove enough heat from the air to keep the inside of the fridge cold. As a result, the temperature inside the fridge starts to rise.
To prevent this from happening, the fridge has a mechanism that kicks in when the door is opened. This mechanism increases the speed at which the Freon gas is compressed and circulated. This allows the fridge to remove more heat from the air and keep the inside of the fridge cold.
So, the next time you are enjoying a cold drink from your fridge, remember that it is the Freon gas inside the fridge that is working hard to keep it cold.
FAQ
Why Do We Need A Refrigerator?
What Are The Benefits Of Having A Refrigerator?
1. Preserving food: A fridge can help to preserve food by keeping it fresh for longer. This is because the fridge slows down the growth of bacteria and other microorganisms that can cause food to spoil.
2. Chilling drinks: A fridge can also be used to chill drinks, such as beer, wine, and soda. This is especially convenient during hot weather.
3. Making ice: A fridge can be used to make ice, which can be used for drinks or for cooling food.
4. Organizing food: A fridge can help to organize food, since it can be used to store food in an organized manner.
5. Saving space: A fridge can save space in a kitchen since it can be used to store food and drinks that would otherwise take up counter or cupboard space.
Conclusion
The name “refrigerator” is derived from the fact that this appliance uses a cooling process to keep food fresh. This process was first used in the early 1800s, and the term “refrigerator” was first used in the mid-19th century.
