YORK® YZ Magnetic Bearing Centrifugal Chiller, a fully-optimized chiller, is built with next-generation low-global warming potential (GWP) refrigerant to increase energy efficiency. The YORK® YZ provides centrifugal-chiller energy efficiencies as low as 0.1kW/ton, and less in off-design conditions where typical fixed-speed chillers experience performance issues. It has the potential to reduce annual electricity consumption by an average of 35 percent. The YORK® YZ was designed with a holistic approach to system design, with engineering optimization for every component around R-1233zd—a next generation, low-pressure refrigerant—and is a unique combination of advanced technologies, including a variable-speed magnetic bearing compressor, high-speed hermetic induction motor, falling film evaporator, adaptive capacity control logic and cloud-based analytics.
