Johnson Controls Introduces YORK YZ Magnetic Bearing Centrifugal Chiller

MILWAUKEE. Wis. – Johnson Controls introduces the YORK YZ Magnetic Bearing Centrifugal Chiller, the first chiller fully optimized for ultimate performance with a next-generation low-global warming potential refrigerant—R-1233zd(E). Chosen for its efficiency, safety, availability, low environmental impact and cost, nonflammable R-1233zd(E) has an ultra-low GWP of 1 and is readily available from refrigerant manufacturers.

Johnson Controls used a holistic approach to system design and engineering, optimizing every component around a carefully selected next generation refrigerant for ultimate performance. The YORK YZ chiller uses an integral, variable speed drive and advanced magnetic-bearing technology that features a single-moving assembly suspended in a magnetic field that does not require lubrication. This technology requires 80 percent fewer moving parts than traditional oil- or refrigerant-lubricated drivelines. The result is enhanced reliability, reduced maintenance and improved efficiency. Compared to traditional fixed-speed oil-bearing chillers, the YZ delivers up to 35 percent annual energy savings.

The YZ chiller can deliver significant energy savings and lower operating costs by taking advantage of the off-design conditions where chillers operate 99 percent of the time. The YZ operates with entering condenser water temperature as low as 40 F (4.5 C), providing enhanced performance in every operating condition and the widest operating envelope in the industry. The YORK YZ uses an optimized single-stage design to provide industry-leading real-world energy efficiency. The chiller can also operate with condenser temperatures below the evaporator temperatures, eliminating the need for a water-side economizer, which simplifies the system, requires less mechanical room space and saves money on components, piping, controls and maintenance.

To view the YZ chiller, visit the Johnson Controls booth at the AHR Expo, Jan. 22-24. The chiller will also be on display at Mostra Convegno Expocomfort in March and China Refrigeration & Heating in April.
