CO2 and R-449A will be used in Beijing’s skating competition venues
According to China’s State Council Information Office, the country is committed to hosting a green Olympic and Paralympic Winter Games. As such, Beijing 2022 has not only made quality ice rinks suitable for respective sports in the competition venues but has also stayed eco-friendly in ice-making.
Behind the process are two types of refrigerants — carbon dioxide (R-744) and R-449A — which the organizing committee chose following careful deliberation and consultation with experts from home and abroad. Of the nine ice rinks in the seven competition venues for Beijing 2022, five used CO2 in ice-making and the other four used R-449A. It is the first time natural CO2 refrigeration system has been used at the Olympic Games.
