It requires a specific combination of heat exchanger, compressor, and motor performance to achieve the lowest system kW/ton. YORK chiller technology matches chiller system components to provide maximum chiller efficiency under actual – not just theoretical – operating conditions.  \nREAL-WORLD ENERGY PERFORMANCE  \nJohnson Controls pioneered the concept of “Real-World Energy” to illustrate the energysaving potential of focusing on chiller performance during off-design conditions. Off-design is not only part load, but full load operation as well, with reduced entering condenser water temperatures (ECWTs) . This is where chillers operate 99% of the time, and where operating costs add up.  \nThe YORK YK chillers are the only chillers designed to operate on a continuous basis with cold ECWT and full condenser flow at all load points, taking full advantage of RealWorld conditions. This type of operation benefits the cooling tower as well by reducing the cycling of the fan motor and ensuring good coverage of the cooling fill.  \nYORK YK chillers offer the most efficient Real-World operation of any chiller, meaning lower operating costs and an excellent return on your chiller investment.  \nOPEN-DRIVE DESIGN  \nHermetic motor burnout can cause catastrophic damage to a chiller. The entire chiller must be cleaned, and the refrigerant replaced. YORK YK centrifugal chillers eliminate this risk by utilizing air-cool","cbCaifBGFS12V2rb","https://ap.wps.com/l/cbCaifBGFS12V2rb","pdf",6409680,118,"English","# Introduction\n# Sustainability Focus\n# Equipment Overview\n# OPTIVIEW Control Center\n# Accessories and Modifications\n# Application Data\n# Dimensions\n# Weights\n# Guide Specifications\n# SI Metric Conversion","[{\"question\":\"Why is YORK YK chiller efficiency described as dependent on matched components?\",\"answer\":\"Actual efficiency depends on a specific combination of heat exchanger, compressor, and motor performance.
