Who invented the refrigerator?

The invention of refrigerator comes from the wisdom of a group of people. The invention of refrigerator can be traced back to:

1 and 1834, jacoby Perkins, an American, found that the evaporation of some liquids can produce refrigeration effect, which laid the foundation for the invention of refrigerator.

2. 1862, john harrison, a printer, washed metal type with ether, and also noticed the cooling effect of the substance, and sold this discovery. At that time, the first batch was produced and listed. Harrison also established the first refrigeration workshop in a brewery in Bendigo, Victoria. /kloc-at the end of 0/9, only the rich who build an ice bank can enjoy this benefit. What most people expect is a refrigerator.

3. 1873, German chemist and engineer Karl von Linde invented a refrigerator with nitrogen as refrigerant. Linde first applied his invention to a brewery and designed and manufactured an industrial refrigerator. Later, he improved the industrial refrigerator and did it very carefully. 1879, manufactured the world's first home refrigerator with artificial refrigeration.

4. 1920, Willis H. Carrier, an engineer in a flat-panel printing factory in Brooklyn, new york, designed a system that can control temperature and humidity. The cellar owner and the manager of the milk company storing fur further improved the mechanical refrigerator technology as needed. During the First World War, some smaller household refrigerators appeared. This is a new invention, which is noisy and easy to leak. In fact, it just installed a motor and a rotating belt in the old "ice box" shell, which made it look like an experiment.

1923, when Quidel Danfray was a branch of general motors, it introduced a new mechanical refrigerator component and assembled it into a refrigerator. FreyGuide refrigerator is designed to put the "ice box" for storing perishable food and refrigeration machinery into a special cabinet. This device is quiet, convenient and compact.

At this point, a new refrigerator style was born, and brand names were everywhere.
