The Beijing Winter Olympics ice venues will use the lowest-carbon carbon dioxide refrigerant in Olympic history. What are its high-tech components?

The new carbon dioxide refrigerant used in the Beijing Winter Olympics is the most environmentally friendly and lowest-carbon refrigerant.

Carbon dioxide refrigerant will be used in the four venues of the Winter Olympics. When this concept was first presented to the Olympic Committee, it was highly praised by the Olympic Committee. This is not only a technological Innovation is also a strong protection of the environment. The working principle of carbon dioxide refrigerant is to evaporate liquid carbon dioxide and absorb heat to complete the process of refrigeration and ice making. In this way, the cooling effect is not only good, but also the cooling is very uniform. There will be no different temperatures in various parts. This is very important for on-ice events. Sometimes a small inappropriateness can affect an athlete's performance.

Carbon dioxide refrigerant is the most environmentally friendly refrigerant. It is natural and environmentally friendly, and is different from commonly used refrigerants that can destroy the ozone layer. Moreover, the heat emitted from liquid carbon dioxide to refrigeration can be reused, saving a lot of energy. The reduced carbon emissions are approximately the annual emissions of 4,000 cars, which is equivalent to planting 1,200 more trees. Today, when the problem of global warming is getting increasingly serious, carbon emissions are becoming more and more important to the public, and this new technology we proposed will undoubtedly show the world that our country attaches great importance to environmental protection.

The development of science and technology is for people to have a better life. However, the current development of the world economy is based on the destruction of the environment. Therefore, environmental protection and low carbon will be the focus of all enterprises in the future* **The same goals pursued. We have set a precedent, and we hope that all countries in the world will have the awareness to protect the environment and a sense of crisis. Only in this way can the world be a better place.
