FEATURE: Johnson Controls launch Magnetic Bearing Centrifugal Chiller

JCI _new YZ Chiller with low GWP refrigerant

Johnson Controls have launched the YORK YZ Magnetic Bearing Centrifugal Chiller, the first chiller fully optimised with a next generation low GWP refrigerant, R1233zd.

Chosen for its efficiency, safety, availability, low environmental impact and cost, non-flammable R1233zd(E) has an ultra-low GWP of 1 and is readily available from refrigerant manufacturers.

Laura Wand, Vice President, Chiller Solutions, Building Technologies & Solutions at Johnson Controls, emphasised Johnson Control’s history of chiller innovation and how the YORK YZ will benefit their customers.

“We have long led the industry in delivering chiller innovations…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, optimising 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 chiller 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 chiller operates with entering condenser water temperature as low as 40OF (4.5OC), providing enhanced performance in every operating condition and the widest operating envelope in the industry. The York YZ chiller uses an optimised 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 economiser, which simplifies the system, requires less mechanical room space and saves money on components, piping, controls and maintenance.

Bill Jackson, President, Global Products, Building Technologies & Solutions at Johnson Controls also emphasised Johnson Control’s history of chiller innovation, as well as how the chiller’s environmentally friendly and optimised features benefits their customers.

“We continue to deliver industry-leading chiller options that best meet the needs of our current and continually expanding customer base around the world…the YZ is another fantastic platform system that equips our customers with environmentally friendly performance in an optimised solution.”

The YORK YZ chiller will be on display internationally over the next four months starting with the AHR Expo in Chicago in two weeks, followed by Italy at the Mostra Convegno Expocomfort in March, followed by China at the China Refrigeration & Heating Expo in April, and here in Australia at ARBS.
