New chiller delivers up to 35 percent annual energy savings, reduced maintenance costs and widest operating envelope in industry
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 (GWP) 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.
“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 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.
“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.”
The YZ chiller brings together groundbreaking YORK® innovations 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.
