Johnson Controls Building Technologies & Solutions is once again thinking big prior to the AHR Expo show, with the release of the YORK® YZ Magnetic Bearing Centrifugal Chiller, described as the first chiller fully optimized for ultimate performance with a next generation low-global warming potential (GWP) refrigerant—R-1233zd(E).
The nonflammable R123zd(E) refrigerant was chosen for its efficiency, safety, availability, low environmental impact and cost, and nonflammable quality. R-1233zd(E) has an ultra-low GWP of 1 and is readily available from refrigerant manufacturers.
The announcement was made during a special webcast with Bill Jackson, president, Global Products, Building Technologies & Solutions at Johnson Controls; Laura Wand, vice president, Chiller Solutions, Building Technologies & Solutions at Johnson Controls; and Daniela Bilmanis, product and strategy manager for the YZ chiller.
“We have long led the industry in delivering chiller innovations,” said Laura Wand, vice president, Chiller Solutions, Building Technologies & Solutions at Johnson Controls. “With the new YORK® YZ, we have engineered the world’s most efficient low-GWP line of centrifugal chillers. Our broad range cooling capacity will serve our customers’ many diverse application needs.”
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 40F (4.5C), 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.
“We continue to deliver industry-leading chiller options that best meet the needs of our current and continually expanding customer base around the world,” said Bill Jackson, president, Global Products, Building Technologies & Solutions at Johnson Controls. “The YZ is another fantastic platform system that equips our customers with environmentally friendly performance in an optimized solution. Thank you to our YORK® Chiller team for leading the way.”
Sources report the YZ chiller brings together groundbreaking YORK® innovations that have been refined over decades of real-world use, to create "a revolution in chiller design and optimization." It represents a solution from the chiller experts, who like to think of the YORK® YZ chiller as tomorrow’s chiller, available today.
