The first refrigerators were very different from the refrigerators we use today. They were usually large, expensive, and only available to wealthy households or businesses.
The first refrigerators used a variety of cooling methods, including ice, ammonia, and ether. Some early refrigerators had a compartment that was filled with ice, which would then cool the surrounding air. Others used a compressor system that circulated coolant through pipes to cool the air inside the refrigerator.

The first refrigerators also had a much smaller capacity than modern refrigerators, with only enough space to store a few days' worth of food. They were often made of wood or metal, with thick insulation to help keep the cold air inside.
Overall, the early refrigerators were a significant improvement over storing food with ice alone, but they were far less efficient and convenient than the refrigerators we have today.
The world has changed in many different ways since the first refrigerators were invented. The technology has changed from ice to gas, from home use to commercial markets, and from traditional glass bottles to reusable plastic ones. The most important thing about these inventions is that they allowed us all access to fresh, healthy food in easy-to-access environments like supermarkets or convenience stores - without having to go out and hunt for it yourself!

The "Fahrenheit thermometer"

In 1765, German physicist Daniel Fahrenheit invented a device known as the "Fahrenheit thermometer." The first version of this invention was made from platinum and mercury. It was later replaced by an improved version made from platinum, brass and silver. It has been used in various countries since then; however, it is most famous for being part of its namesake's name (which he chose because of its similarity to his father's name).

The first practical self-contained refrigerator

Ida McKinley Noble built the first practical self-contained refrigerator in 1893. She used it to store food during a picnic she took her mother on an outing through Kansas City's zoo. At the time, refrigerators were not common household appliances and people didn't have access to them in their homes. This meant that most foods needed to be kept cold at all times - especially during summer months when temperatures reached the 90s Fahrenheit.
In fact, there weren't even any commercial fridges until the early 1900s!

The first modern refrigerator

In 1911, German-American inventor Heinrich Hertz built and operated one of the first refrigerators in Massachusetts. He was a mechanical engineer and inventor who had been working on his own development of an electric motor compressor since 1898.
In 1900 he set up his own company to manufacture electric motors for refrigeration systems. Heinrich Hertz's first refrigerator was powered by an internal combustion engine that generated electricity using electrolysis (the process of splitting ions from water). This type of compressor was much smaller than the ones used today. Still, it used a lot of power because it required both heat from an external source such as gas or electricity as well as cooling water from inside itself that could come either directly through pipes or indirectly through evaporation.

Fridge for trucks

In 1914, William Caffery created an electric refrigeration unit for ice cream trucks. This led to many new innovations in cooling technology.
While William Caffery is credited with inventing a refrigerated truck. The first refrigerated truck was actually invented by Frederick McKinley Jones in 1935.
Jones was an African American inventor and engineer who is known for his work in the field of refrigeration. In addition to the refrigerated truck, he also invented the first portable air-cooling unit for military field hospitals during World War II. Jones was awarded over 60 patents during his lifetime and is considered to be one of the most prolific inventors of the 20th century.
