What is the ice-making process of the ice rink in the Winter Olympics? In order to meet the competition of the Winter Olympics, it was rebuilt and expanded on a large scale, inherited the concept of green technology, and added the ice-making function on the basis of the original facilities. In the museum, there will be two competitions: short track speed skating and figure skating. The skating rink in the museum can be converted into multi-function to meet the needs of the competition. The ice in the skating rink is made of the most advanced carbon dioxide ice-making technology in the world.
Carbon dioxide ice making technology is the most advanced ice making method at present. This time, carbon dioxide technology is the most advanced and environmentally friendly technology in the world. The ice made in this way can keep the temperature difference of the ice surface within 0.5 degrees, and the environmental protection utilization rate of heat energy is also very high. According to statistics, it can save more than one million kwh of electricity every year, which fully embodies environmental protection and green. Compared with the traditional ice-making method, this ice-making method has more uniform refrigeration, can also improve energy saving by 30%, avoids the different temperatures of different parts in traditional ice-making, and can carry out site conversion faster and more effectively.
Compared with the traditional built-in skating rink, this Winter Olympics also adopted clean and low-carbon carbon carbon dioxide transcritical direct cooling ice-making technology for the first time, which improved the energy efficiency by more than 20%. The curling project that needs the most space also needs a professional ice machine to complete. The venue of curling competition needs to be hand-made on the concrete floor with an ice machine. First, the first layer of ice with higher hardness is poured out evenly, and then painted to make the ice rink look pure white. Curling track requires high accuracy of scoring, and all lines such as pedal, baseline, frontcourt throwing line and center line must not be deviated, otherwise athletes and referees will misjudge during the competition, which is a very delicate work. When it's over, the track will be replenished with water. It takes three to four hours to repair each floor, and two to three days to completely repair it. Finally, an absolutely flat upper ice surface without bubbles and impurities will be formed.
