2017/11/26
On April 12, 2017, on the first day of the China Refrigeration (CRH) expo, Haier Commercial Air Conditioner released a magnetic bearing centrifugal chiller with the largest cooling capacity of 4,200 tons in the industry and the largest cooling area of 100,000 m2.
 
Haier started to develop magnetic bearing centrifugal chillers in 2006. In the past 11 years, it has constantly expanded the capacity of its chiller from 80 tons in 2006 to 900 tons in 2011, and then to 2,200 tons in 2015, which was the largest in the industry at that time. Finally, the 4,200-ton capacity was reached in 2017, setting a new technical record.
 
Thanks to key technologies, namely oil-free, zero friction operation, inverter, and two-stage sub-cooling, the product has reached a high integrated part load value (IPLV) of 13.18 and energy savings of 50%.
