What inspired the refrigerator was invented

1. The world's first refrigerator was born in 1918 and was designed and manufactured by E.J. Coberland, an engineer from Carl Viyun Rannath Company in the United States.

In the years, American engineer Jacob Perkins invented the world's first compression refrigeration device, which was the prototype of the modern compression refrigeration system. In the same year, Perkins received the first patent for a freezer issued by the British Siege State.

The refrigerator is now one of the essential appliances in every home, and it is a must-have product for our food insurance, drug insurance, and refrigeration. It can be said that the extensive use of refrigerators has made our food more abundant, life more convenient, and social efficiency has been greatly improved, so how did such an excellent product appear, and who invented the refrigerator?

Through the understanding of low-temperature preservation, in 1822, the British inventor Faraday discovered the theory that when a liquid vaporizes into gas, it will absorb a large amount of heat and rapidly reduce the surrounding temperature. Through the in-depth practice and research of this theory, this theory has become the main theoretical basis for the invention of refrigerators later.

Based on the above theory, the German Karl von Linde invented the refrigeration machine for ammonia refrigeration, and later he improved the refrigerator to make it smaller and became the first refrigerator. This refrigerator mainly relies on steam power, and after its release, more than 12,000 units were sold in Germany and the United States.

However, we are currently using fluorine-free refrigerators, the inventor of this refrigerator is difficult to say who is specific, the earliest fluorine-free refrigerator in history was invented by Fulong Household Appliances Company in 1993. Therefore, the inventor of the fluorine-free refrigerator can only be the legal person of Fulong Company. I believe you know who invented the refrigerator.

The widespread use of refrigerators was not after the invention of the steam refrigerator, but long after its invention. Steam refrigerators are difficult to use widely because the power is steam, and the steam engine is huge, so the refrigerator has undergone many improvements later. These include the change of power to electricity, the change of refrigerant to the invention of the fluorine-free refrigerator.

After many improvements, refrigerators are gradually entering every home.

After more than 100 years of invention and improvement of the refrigerator, he is the crystallization of the wisdom of chemists and engineers, although the refrigerator seems to be very ordinary, but the efforts of scientists behind it and the value it brings are immeasurable, so please cherish the refrigerator at home.

The refrigerator has become an indispensable item in most households, which can be used to preserve food and enhance its shelf life. And as the time of invention and the inventor of the first refrigerator, not many people know. So when was the refrigerator invented, and how to choose a refrigerator, do you understand?

1. When was the refrigerator invented.

The first refrigerator was invented in 1923, using an electric motor and a compressor to work together, developed by Swedish engineers. In 1925, the patent for the refrigerator was purchased by an American company to develop the first household refrigerators, and refrigerators began to enter people's lives.

Second, how to choose a refrigerator.

1. When buying a refrigerator, you need to carefully see whether the outer surface of the refrigerator is damaged, whether the refrigerators are deformed, and you must know that a small defect will affect the later use. Then check the condenser and capillary behind the refrigerator to make sure that it has no external injuries and that the pipes are not flattened, so as to enhance the service life of the refrigerator.

2. Pay attention to the refrigerator door seal to see if it can be closed tightly, at this time, you can use a paper strip to clamp it at the door crack of the refrigerator door, and then close the refrigerator door. If the note will fall, it means that there is a problem with the door seal, and you must not choose it.

3. The refrigerator will be designed with a lighting bulb to facilitate the use of the refrigerator at night, when the refrigerator door is opened, the lighting will be lit up, and after the refrigerator is closed, the lighting will be extinguished. If the lamp is damaged, it will inevitably affect the future use. Then observe the compressor of the refrigerator to see if it can be used normally.

About when the refrigerator was invented, and how to buy a refrigerator, I will introduce it here, do you understand? The purchase of refrigerators requires attention to many small details, and the purchase of the best refrigerator can ensure normal use in the later stage and is not easy to be damaged.
