The Xiecheng air-bearing centrifugal chiller is a water chiller unit designed with a centrifugal compressor supported by air bearings at its core. The entire series of Xiecheng air-bearing chillers meet the National Standard Energy Efficiency Grade I. Under standard working conditions, the COP can reach 7.0, and the comprehensive part-load performance coefficient can reach 11.0, featuring dual Grade I energy efficiency of GOP/IPLV. With a perfect design and high-efficiency components, the air-bearing centrifugal chiller has an energy efficiency ratio about 50% higher than that of ordinary screw units, about 25% higher than that of traditional centrifugal or VRF units, and about 6% higher than that of magnetic suspension units.
