Johnson Controls introduced the YORK YVAM air-cooled, magnetic-bearing, centrifugal chiller operating with the ultralow-global warming potential (GWP) refrigerant, R-1234ze, for hyperscale and colocation data center cooling.
The YVAM chiller is one of the most efficient options for data center applications, because its magnetic-bearing technology allows the system to operate very efficiently at low-lift conditions. This means the chiller doesn’t need free cooling coils to deliver performance comparable to air-cooled chillers with integral water-side economizers. Compared to traditional air-cooled screw chillers, it can improve efficiency by 49% in nonstandard part-load value (NPLV) in typical data center conditions.
