YORK Launches Air-Cooled Variable Speed Drive Screw Chiller
Johnson Controls has launched its air-cooled variable speed drive screw chiller in the United States to use ultra-low-global warming potential refrigerant R-1234ze.
The YORK YVAA Style B Air-Cooled Screw Chiller, an evolution of the first-generation YVAA, is engineered to drive efficiency now and meet or exceed future regulatory requirements. The R-1234ze refrigerant has a zero-ozone depletion potential and a GWP of seven, which is well below the Environmental Protection Agency’s SNAP requirement, making the YVAA Style B a future-forward solution for hydrofluorocarbon phase-down requirements.
In addition to the use of ultra-low-GWP R-1234ze, the product features next-generation condenser coils to minimize refrigerant quantity and further reduce its carbon footprint. A newly designed compressor optimizes part-load efficiency to deliver a significant reduction in annual energy consumption. Series flow evaporators coupled with falling film technology help achieve market-leading performance.
The chillers can operate from a wide range of -10 F to 130 F ambient temperatures. It can reach capacity ranges spanning from 100 TR to 400 TR for comfort cooling applications, and 200 TR to 500 TR compatible with data center mission critical requirements.
