Meilleures pratiques Haier Carrier’s Sustainable Ice Making Technology Creates Optimal Conditions for Record-Setting Performances at National Speed Skating Oval in Beijing
In February 2022, the National Speed Skating Oval (NSSO), also called the "ice ribbon," held its inaugural international competition in Beijing with athletes setting 10 new records and a world record in speed skating. Qingdao Haier Carrier Refrigeration Equipment Co., Ltd. (Haier Carrier) introduced the transcritical carbon dioxide (CO2) ice making system for the NSSO. Haier Carrier is a joint venture established in 2001 by Haier Group and Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions. To create higher-quality ice, the NSSO utilized carbon dioxide (CO2 ) as a natural refrigerant for its ice-making technology, a historic first for the indoor ice venue. Speed skating requires extremely flat ice surfaces. The smaller the difference in temperature between ice and the surface, the flatter the ice. The new technology can control ice temperature variances within 0.5 degrees. To ensure the ice surface remains in peak condition, it must be resurfaced six to seven times a day during competitions. Carrier's transcritical CO2 ice making system takes less than 10 minutes to ensure that the ice surface is restored to competition standards. The NSSO covers an area of about 12,000 square meters, almost equal to the size of a track field. The ice making system uses Carrier’s high-capacity PowerCO2OL solution and consists of several high-capacity racks with 4 MW max cooling capacity running on natural refrigerant CO2, which has a low global warming potential (GWP) of 1 and near-zero carbon emissions. With more than 30% energy savings compared to a standard system, Carrier’s transcritical technology achieves optimized energy efficiency. In post-event operation, it can save nearly two million kilowatt- hours of electricity each year, making the ice rink an environmentally sustainable venue. Carrier’s transcritical CO2 technology is also used in all types of high-energy applications such as medium and large warehouses, distribution centers and food processing sites.

Meilleures pratiques New ‘Smart Store’ paves the way for 21st century supermarkets
New “Smart Store” will work as Danfoss’ test center for energy efficiency technology. ‘The Smart Store’ is expected to be approximately 50% more energy efficient compared to a typical supermarket with a first-generation CO2 refrigeration system. - Runs off sustainable energy sources - Reuses the excess heat created by cooling cases, reducing supermarket heating costs by up to 90% - Not only operates as a functioning supermarket, but is also a development center for testing new technology Scalable technologies The installations and technologies in the supermarket are scalable. They can be applied in the smallest store up to the biggest hypermarket. The supermarket cooling (refrigeration and comfort cooling) systems run exclusively on natural refrigerants (CO2). CO2-based refrigerants do not deplete the ozone layer and have the lowest possible Global Warming Potential (GWP) score. In addition, CO2 refrigerants outperform traditional HFC-systems when it comes to energy efficiency in different weather conditions. The supermarket is equipped with a heat recovery unit capturing excess heat from the cooling systems to provide space heating for the entire store as well as the surrounding community through the district heating network. The heat recovery unit, can by re-using the excess heat from the cooling system, reduce the external heat requirement with up to 89,7%. Furthermore, the energy pack can supply additional heating and cooling when needed. Smart energy systems applied 100 KW solar panels on the roof help to optimize store operations. On sunny days, solar energy can be accumulated in the freezers. Turning the temperature in the freezers further down from e.g., -18 to -25 help accumulate solar energy ( while reducing battery storage). When the solar panels are less efficient due to no sun the temperature rises back to normal settings. Co-developing with customers The supermarket has two separate refrigeration systems installed that run independently of each other. Therefore, operations of a supermarket continue while Danfoss co-develops new solutions with customers. And when future applications are being tested, the cooling cabinets and freezers stay cool. …
