The idea of using a low-temperature environment to prevent food spoilage has been around for centuries. The creation of the familiar home appliance resulted from a series of innovations by chemists, engineers, and inventors over the span of the 18th and 19th centuries. The American inventors Oliver Evans, Jacob Perkins, and John Gorrie are credited with developing the earliest versions of the modern refrigerator in the early 1800s. Later that century, the work of German engineer Carl von Linden allowed chemical refrigerant to be stored efficiently, paving the way for mass production of refrigerators.

Early Efforts at Food Preservation

Human cultures have long known that cold temperatures can protect valuable foodstuffs from bacteria and other factors that may render them inedible. Preservative methods such as salting and drying were also effective, but these were not well suited to all kinds of food. Before mechanical refrigeration was widely available, many cultures used well-insulated buildings called icehouses for food storage, using winter ice and snow as natural coolants. These structures date to the second millennium BC in Europe and Asia, and the names of the engineers who designed them have been lost to history.

The First Refrigerators

Icehouses were used well into modern times, particularly in rural areas where electricity and appliances were expensive or unavailable. In the early 1800s, American engineer Thomas Moore created a home version of the icehouse, a portable insulated chamber cooled by block ice. Moore coined the term "refrigerator" to describe his invention, although it came to be more commonly known as the "icebox." Iceboxes had the same general shape and function as modern-day refrigerators and some people still use this name. In many areas, a local delivery person, colloquially known as an "iceman" in the U.S., would bring fresh ice blocks to neighborhoods in a cart or truck.

In the 1750s, Scottish physicist William Cullen discovered that some chemical reactions would draw heat away from a particular area, creating a pocket of cold. Cullen, unconcerned with the practical applications of his discovery, did not realize he had found the basis for modern refrigeration. Around the same time that Thomas Moore invented the icebox, Oliver Evans designed, but did not build, a machine to make use of Cullen’s chemical process. It was not until 1834 that scientist Jacob Perkins built and patented the first functioning refrigerator. Perkins, a major figure in American engineering, also tinkered with heating and cooling systems for the home and is sometimes called the father of refrigeration.

Ten years later, U.S. physician John Gorrie was seeking a steady source of ice to lower the body temperature of patients suffering from yellow fever. The ice delivery methods common at the time were insufficient for his purposes so, working from Evans’ original design, he built a refrigeration unit that was more practical and efficient than the one created by Perkins. This was the model for the modern refrigerator. As a result, Evans, Perkins, and Gorrie can effectively share credit for this now-essential device.

The Refrigeration Process

Mechanical cooling systems depend on chemicals called refrigerants. As the refrigerant moves through the appliance, it is compressed, which raises its temperature. That heat is released from the back of the refrigerator; as the heat is dissipated, the refrigerant condenses but stays at that high pressure. The refrigerant then moves through an expansion valve, where the pressure drops and it turns back into a gas. As it changes from liquid to gas, its temperature falls, cooling the air. Fans and motors circulate this cooled air within an insulated area.

The first refrigerators used liquid refrigerants like ether, but in 1876, Carl von Linden discovered an improved method of liquefying gas. This made the mass production of refrigeration devices practical, paving the way for their widespread sale and use in the 20th century.

There were still severe problems with the design, however. Early refrigeration units used highly toxic gases such as ammonia, sulfur dioxide, and methyl chloride. The chambers containing these gases sometimes leaked, resulting in several fatal home accidents in the early 1900s. Appliance manufacturers realized that a safer cooling element was needed, which led to the discovery of synthetic refrigerants called chlorofluorocarbons (CFCs). Also known collectively as Freon®, they became the standard refrigerant worldwide in the decades that followed.

Freon® was not a perfect solution either, however. In the 1970s, scientists discovered that CFCs contribute to the depletion of the Earth’s natural ozone layer. Ozone depletion, which increases the damaging health effects of solar radiation, was soon understood as a major environmental crisis. World governments banned the use of CFCs in the 1980s, although it would be decades before all the devices that employed them would be out of service. Modern refrigerators use safer alternative refrigerants, and their highly efficient machinery typically requires smaller amounts of chemicals than were used by older units.

I need to know who exactly invented the very first refrigerator.

By anon951711 — On May 17, 2014

The "modern refrigerators" use propane or similar gases. Although they're both hydrocarbons, the ether is a lot more dangerous. Of course, that's like saying that thrown knives are less dangerous than stray bullets.

By anon350754 — On Oct 08, 2013

Thomas Elkin patented it in 1897 so his version could chill a human corpse.

By anon321804 — On Feb 24, 2013

Look up Thomas Elkins or John Standard.

By anon233567 — On Dec 07, 2011

Who really invented the very first fridge?

By anon155466 — On Feb 23, 2011

but who invented the very first refrigerator?

By anon155159 — On Feb 22, 2011

There is no mention of a woman, Florence Parpart, who is listed as inventing the refrigerator in 1914.

By anon139788 — On Jan 05, 2011

I just learned some awesome stuff.

By anon131964 — On Dec 04, 2010

this website really helped for a huge part of a grade i got.

By anon127599 — On Nov 16, 2010

I think that this website was a lot of help to me but i just want to know who the single inventor is. I'm so confused. All of the web sites i go to won't give me a straight answer but you guys really made it easy to understand.

By anon114197 — On Sep 27, 2010

this was great info and i bet it will give me an a+ but if it doesn't i will let you know. i hope this is what i am looking for!

By anon92559 — On Jun 28, 2010

what does it mean by "until it was leaked to damage to the ozone layer"?

By anon92379 — On Jun 28, 2010

I agree with #12. I just wanted to know who designed what is the forerunner of the modern day fridge we find in our homes. Not ice boxes or cooling methods, etc. And if you think this is frustrating, just try to find out who invented the toilet!

By anon85953 — On May 23, 2010

Sorry mate, John Standard's contribution wasn't mentioned because he is a black man.

By anon84258 — On May 14, 2010

Good site. helped me some, but i was looking for modern, oh well. still good. thanks.

By anon82311 — On May 05, 2010

this is so confusing because i just want to know the one person who got credit for designing and making the first actual working refrigerator.

By anon80878 — On Apr 29, 2010

Why is there no mention of John Standard?

By anon80835 — On Apr 28, 2010

But where was it invented?

By anon77998 — On Apr 16, 2010

I love this website, but I really thought Jacob Perkins invented the refrigerator! I think I will rethink because I think you are right!

By anon75743 — On Apr 07, 2010

This website really helped my prepare for my merit badge university.

By anon72749 — On Mar 24, 2010

Wow this website gave me all the information that i needed to know! Wowzers. Now i can finish my project that i had due in class! Thanks for whoever did this, it was a really big help! ~Add~

By anon52820 — On Nov 17, 2009

this website rocks. --Shaundra

By anon25198 — On Jan 25, 2009

Worth mentioning is John Standards' contribution to the improvements to the design of the refrigerator in June 1891. U.S. Patent # 455,891.
