2022 Beijing Winter Olympics ice venues will use environmentally friendly advanced refrigeration technology

2022 Beijing Winter Olympics ice venues will use environmentally friendly advanced refrigeration technology

On July 30, a press conference on the construction of venues for the 2022 Beijing Winter Olympics and Paralympics was held in Beijing. It is reported that the 2022 Beijing Winter Olympics will use 8 ice stadiums and 10 ice surfaces. Except for the first figure skating training hall that uses the original refrigeration system because the ice surface has not been modified, the other 7 stadiums have 9 ice surfaces. Environmentally friendly refrigerant is used.

Among them, four venues, the National Speed Skating Stadium, the Capital Gymnasium, the First Short Track Speed Skating Training Hall and the Wukesong Ice Hockey Training Hall, use a carbon dioxide transcritical direct refrigeration system. The carbon dioxide transcritical direct refrigeration system is the most advanced, environmentally friendly, and energy-saving refrigeration technology in the world. This is the first time in the history of the Winter Olympics.

In addition, the National Aquatics Center, National Stadium and Wukesong Sports Center adopt traditional refrigeration systems due to the actual needs of post-match use, and the refrigerant uses environmentally friendly refrigerant R449A.
