technology creates ice and snow. In the Winter Olympics, ice and snow are the absolute protagonists. However, the Winter Olympics requires very strict ice and snow for competition. In order to meet the competition requirements, scientific and technological assistance is essential. In addition to the well-known carbon dioxide transcritical direct refrigeration technology, in order to maintain the smoothness of the ice surface, the temperature was adjusted until the researchers added black technology to the ice-making car. The ice-making car in Beijing Winter Olympics adopts advanced digital refrigeration equipment, and realizes "accurate ice making" by controlling equipment parameters, thus ensuring the smoothness and temperature of the ice surface and creating good ice conditions for athletes. There are 6 skiing events in the 15 disciplines of the Winter Olympics.

Snow-making equipment

funa machine is an electrical device that can quickly convert a large amount of liquid water into high-pressure atomized ice crystals, which is mainly used in funa, artificial ski resorts and fire fighting. Funa machine is not affected by climate, so long as it can keep a certain amount of water, it can make snow.

The photos taken by magic eye, a timing device

, can solve the battle of winning or losing that the referee at the finish line can't judge with the naked eye. The accuracy of "magic eye" is extremely high, surpassing all previous equipment.
