How did the ice maker come about

The early written records of the preservation of ice cubes should come from China. In the late Spring and Autumn Period, there were records of taking ice from the "cellar" and adding rice wine to drink it. The so-called "cellar", which is the ice cellar. Because most human settlements in ancient China had four distinct seasons, when lakes and rivers froze in winter, people would take ice from them and store them in ice cellars. Take it out for use in hot summer.

And it was China who invented Compressor Refrigerator technology in the first place. As early as the Tang Dynasty, there were records of making ice with saltpeter. The main component of saltpeter is potassium nitrate. When potassium nitrate is dissolved in water, it will absorb a lot of heat. People at that time used this feature to make ice cubes. Modern air-conditioning refrigeration and even ice-making technology originated in America in the mid-nineteenth century.

In order to provide air-conditioning for his high-fever patients, a doctor at that time used the physical principle that air absorbs heat when expanding, and used a steam engine as a power source to invent the initial air conditioner. The doctor did not later develop a new industry based on this invention, but the idea was carried forward by other engineers, and another French engineer developed a more complete refrigerator.

Therefore, in the North-South period of the United States, this invention achieved great development because of the airtight transportation of ice from the north to the south. Since then, mankind has entered the era of large-scale refrigeration.
