Haiyan-based Air Com (Zhejiang) General Equipment Co Ltd in Jiaxing, East China's Zhejiang province, serves as the supplier of fluid reservoirs for the National Speed Skating Oval, a symbolic venue for the Beijing 2022 Winter Olympics.

In response to the call for zero-carbon emissions, low-energy, heat recovery, and non-pollution, the National Speed Skating Oval is the first of its kind in the world to adopt "transcritical" CO2 refrigeration systems.

Fluid reservoirs are the core components of the CO2 refrigeration system and are key to maintaining the system's stable operation.

The CO2 refrigeration system at the National Speed Skating Oval has been functioning well, and in a few days, speed skating competitions will be held at the venue where 14 gold medals will be given out.

Air Com, founded in 2021, is a subsidiary of Italy-based Baglioni Group, a renowned pressure vessel supplier in Europe. It generated 130 million yuan ($20.53 million) in output last year.
