Dalian Bingshan Group provided top-quality refrigeration equipment and high-standard technical services for three ice sports venues during the 9th Asian Winter Games in Harbin, Heilongjiang province, from Feb 7 to 14.

"We have continuously iterated and upgraded equipment like ice-making units. Compared to serving the 2022 Beijing Winter Olympics, our products have seen significant improvements in compactness, energy efficiency and control systems," stated Li Shuang, an expert from Bingshan Group, which is based in Dalian, Liaoning province.

Li explained that the company's direct refrigeration ice-making units allow the refrigerant to directly cool the ice surface, which separates them from commonly used secondary refrigeration ice-making units.

"Under matching conditions, our units can reduce energy consumption by 15 to 20 percent," he said.

Moreover, this technology ensures better uniformity in ice surface temperature and hardness, providing a more stable playing surface for athletes, he added.

With a history spanning 95 years, the company is a leading enterprise in China's refrigeration and air conditioning industry.

It constructed the country's first artificial ice sports venue in 1968 and was involved in projects like the Ice Cube for the 2022 Beijing Winter Olympics and the Wukesong sports center.

In 2023, Bingshan Group upgraded the ice rink technology used during the Winter Olympics and constructed China's first zero-carbon ice rink, the Bingxiong ice sports center in Shahekou district, Dalian.

It demonstrated the application of energy-saving technologies such as a 60 percent energy-saving five-in-one cold and heat comprehensive utilization technology and rooftop photovoltaic power generation technology.
