Beijing, the city of two Olympics, won the bid for the key project of Winter Olympics in 2022, the CO2 trans-critical direct cooling ice-making system of the National Speed Skating Oval, the ice-making and dehumidification system project of the Olympic curling competition venues, which will continue the Olympic Games after the 2008 Summer Olympic Games and contribute to the ice and snow industry of the motherland.

The National Speed Skating Oval, also known as the "Ice Ribbon", is the only new ice competition venue in the Beijing Olympic Winter Games. The main stadium covers an area of about 80,000 square meters and can accommodate 12000 spectators. The interior of the National Speed Skating Oval is specially designed with full ice surface, and the 12,000 square meters of ice surface built by Pan-China Sports and Consortium is the largest in Asia.

After completion, the National Speed Skating Oval will be a green and environmentally friendly intelligent venue. With the support of the Internet of Things and big data technology, it will meet the three-star standard of green buildings. In the "Ice Ribbon" project, Pan-China Sports and Consortium will adopt advanced CO2 transcritical direct expansion unit and direct cooling ice-making technology, and at the same time, it will be equipped with a full-ice ice-making control system. It can accurately control the temperature, thickness and stability of the ice surface in different areas, and the waste heat generated in the refrigeration process can be recycled for stadium heating, athletes'shower, ice melting and dehumidification. Such a fantastic and smart "Ice Ribbon" is expected to be completed by the end of 2020.

The National Aquatics Centre, also known as the Water Cube, is one of the major competition venues for the Beijing 2008 Olympic Games.
