The Origins Of Ice History

- May 17, 2017-

The earliest written records of storing ice should be from China. In the late spring and Autumn period, there is a record from the "cellar room" to take ice and drink wine. The so-called "cellar room" is Bing Jiao. Because most of the ancient Chinese people inhabited areas of four distinct seasons, winter lakes and rivers freeze, people will take ice from it, and then save in Bing Jiao. It is used in the hottest summer.

And the earliest invention of ice-making technology is also China. Early in the Tang Dynasty, there are saltpeter ice-making records. The main ingredient in saltpeter is potassium nitrate, which absorbs a lot of heat when the potassium nitrate dissolves in water, when people use this feature to make ice cubes.

and modern air-conditioning refrigeration and even ice-making technology is originated in the middle of the 19th century in the Americas. A doctor at that time in order to give his high fever patients to provide air-conditioning, the use of air expansion will absorb the physical principle of heat, using the steam engine as the source of power, the invention of the earliest air-conditioning. The doctor did not rely on the invention to develop a new industry, but the idea was built by other engineers, and another French engineer developed a more sophisticated cooler. In the American Civil War, this invention has gained tremendous development because of the blockade of the southern ice transport in the north. Since then, mankind has entered the era of large-scale refrigeration.
