Johnson Controls Launches New Magnetic Bearing Chiller

Johnson Controls has launched YORK YVAM air-cooled magnetic bearing centrifugal chiller working with the ultra-low international warming potential refrigerant, R-1234ze, for hyperscale and colocation information heart cooling.  

The chiller is an environment friendly possibility for information heart functions, as a result of its magnetic-bearing expertise permits the system to function very effectively at low elevate situations. This implies the chiller doesn’t want free cooling coils to ship efficiency corresponding to air-cooled chillers with integral water-side economizers.​ In comparison with conventional air-cooled screw chillers, the YVAM can enhance effectivity by 49% in non-standard half load worth in typical information heart situations. 

The chiller makes use of a variable-speed drive with lively front-end to decrease vitality consumption and whole harmonic distortion. This implies the magnetic driveline is considerably quieter than conventional air-cooled chiller drivelines that use screw compressors. Full-load sound is barely 65 dBA at a distance of 10 meters. The machine’s lubrication-free design additionally eliminates the complexity of subsystems and reduces the prices of routine upkeep and system checks.  

Knowledge facilities and different mission essential amenities require continuous cooling. An influence failure might jeopardize operations and result in expensive downtime and efficiency penalties. To maximise uptime, the YORK YVAM options fast begin expertise with integral uninterruptible energy provide backup, permitting the chiller to return to full load in as little as three minutes after energy is restored.
