IntroductionFORM 201.21-EG1 (711)YORK YCAV Air Cooled Screw Liquid ChillersJohnson Controls has a proud history of innovation in both compressor design and variable-speeddrive (VSD) technology. The Latitude TM air-cooled chiller uses the best of modern screw compressordesign and manufacturing techniques and combines them with the latest in a long line of chillervariable-speed drives. The result is superior control and industry leading efficiency at real worldconditions. In addition, by slowing the speed of the chiller to match system requirements at off-designconditions, the chiller sound output is reduced when it is the most sensitive to neighbors – eveningsand weekends.With the introduction of the YORK YCAV model air-cooled chiller, system designers are given theLatitude to design around the traditional benefits of air-cooled chillers and still offer building ownersenergy efficient system design. In the past, the choice to use an air-cooled chiller came with theexpectation of compromise, where simplicity of design and maintenance were traded for performanceand efficiency. Now combining the best of both worlds can provide a design that truly delivers thelowest total cost of ownership.JOHNSON CONTROLS3
