Hailiang Business Hotel in Zhuji replaced its existing R22 heat pumps with six ITOMIC 65kW (18.5TR) units.
The country says it has also implemented an HFC import/export licensing system as of November 1, 2021.
As one of the world’s biggest users of f-gases, China’s acceptance of the amendment is important for the phase down of HFCs.
Two systems installed in existing stores were forecast to save 25% in energy consumption compared to previous R22 systems.
The transcritical system will provide 1.1MW (312.8TR) of cooling capacity for the speed and figure skating rink at the Beijing Capital Indoor Stadium.
Transcritical systems in Suzhou and Wuxi are being used to meet the increasing demand for natural refrigerant-based systems in the country.
A major user of CO2 in Japan, Lawson employs both transcritical CO2 and hydrocarbon cooling at Shanghai store.
Installed at a CSF Market store in Beijing last year, the energy-efficient system is performing reliably, according to Panasonic at ChinaShop 2019.
