R1234ze chiller for data centre cooling

United states of america: Johnson Controls has introduced the launch of its York YVAM air-cooled magnetic bearing centrifugal chiller with lower GWP refrigerant R1234ze for hyperscale and colocation facts centre cooling.

The YVAM’s magnetic-bearing technological innovation lets the procedure to operate very efficiently at small carry disorders. This usually means free of charge-cooling coils are not required to provide performances comparable to air-cooled chillers with integral water-side economisers.

According to Johnson Controls, when in comparison to conventional air-cooled screw chillers, the YVAM can strengthen performance by 49% in non-standard section load worth (NPLV) in standard information centre circumstances,

“The pioneering layout of the York YVAM chiller was specified for the exceptional needs of mission important purposes, that includes business-main performance, simplified design and style and small harmonics,” mentioned Chris Paraskevakos, Johnson Controls’ vice president of product management, chillers and used machines. 

The YVAM chiller uses a variable-velocity push with energetic front-conclude to reduced strength consumption and full harmonic distortion. This indicates the magnetic driveline is noticeably quieter than common air-cooled chiller drivelines that use screw compressors, Johnson Controls claims. Comprehensive-load seem is said to be only 65dBA at a distance of 10m. The machine’s lubrication-no cost layout also eliminates the complexity of subsystems and decreases the prices of plan upkeep and program checks.

To maximise uptime, the YVAM functions quick start technological know-how with integral UPS backup, allowing the chiller to return to comprehensive load in as little as 3 minutes soon after electricity is restored.
