Refrigerators are a staple in most homes, and their popularity is only increasing as time goes on. Though the refrigerator has been around for over a hundred years, people are still reliant on its ability to keep food cold.
In this article, we will explore the history of refrigeration, how refrigerators work, and different types of refrigerators so that you can make an informed decision when it comes time to purchase one for your home. Let's dive deep into this topic.
The history of refrigeration
In 1834, Jacob Perkins, an American living in London, developed the world's first working vapor-compression refrigeration system. His prototype system used a pump to create a partial vacuum over a container of diethyl ether, which boiled and condensed on the walls of the container. The boiler was then cooled by cooling water, and the condensed ether was drawn off for use as a refrigerant.
While this fridge was the first step to creating a working compression refrigerator, it didn't succeed commercially.
Refrigerators for home usage were first produced in 1913. In 1923, Frigidaire launched the initial self-contained unit. This spelled the beginning of the end for iceboxes. After that, it was one improvement after another.

How the modern refrigerator works
As a modern appliance, the refrigerator works using the laws of thermodynamics. When you open the door, cold air rushes out and warm air rushes in. The compressor then works to cool the warm air back down to the desired temperature.
The compressor is what makes the noise that you often hear coming from your fridge. It is a pump that pressurizes refrigerant gas and circulates it through the system. As the refrigerant evaporates, it pulls heat away from whatever it is cooling and blows warm air out of the fridge.
The evaporator coils are what get cold when you turn on your fridge. They are filled with a liquid refrigerant, which expands and vaporizes when it comes into contact with the warm air inside your fridge. This process sucks the heat out of the air and cools it down.
The expansion valve is a small, throttle-like device that regulates the flow of refrigerant into the evaporator. It is important because it prevents the refrigerant from vaporizing too quickly, which can cause damage to the compressor.
Finally, the condenser coils are what release the heat that has been pulled out of the fridge. These coils are located on the back of the fridge, and they release heat into the air through convection.
Different types of refrigerators
There are many different types of refrigerators on the market today, each with its own set of benefits and drawbacks.
- Side-by-side: Side-by-side refrigerators are a popular choice for many homeowners because they offer ample storage space and are easy to organize. However, they can be difficult to keep clean because of all the nooks and crannies, and they often cost more than other types of refrigerators.
- Top freezer: Top freezer refrigerators are one of the most popular types on the market because they are affordable and spacious. However, it can be difficult to reach items that are stored in the back, and they often require more energy to operate than other types of refrigerators.
- Bottom freezer: Bottom freezer refrigerators offer the benefit of having the most used items at eye level. They are also generally more energy-efficient than top freezer models. However, they can be more expensive, and they often have less storage space than other types of refrigerators.
- Compact: Compact refrigerators are a good choice for small spaces or people who don't need a lot of storage space. However, they can be more expensive than other types of refrigerators, and they often don't have all the features that larger models do.
- French door: French door refrigerators are becoming increasingly popular because they offer the benefit of having both a bottom freezer and a side-by-side model. They can be expensive, but they offer a lot of storage space and features.
- Undercounter: Undercounter refrigerators are a good choice for people who want to save space. They can be installed under a counter or in a cabinet, and they often come with features like ice makers and water dispensers. However, they can be more expensive than other types of refrigerators, and they often don't have as much storage space.
- Portable: Portable refrigerators are a good choice for people who want the flexibility to move their fridges around. They are small and lightweight, and they can be plugged into any standard outlet. However, they often don't have all the features that larger models do.
How to choose a refrigerator for your needs
