CG-PRC012-EN 4 The standard ARI rating condition (54/44°F and 85°F/3.0 gpm per ton) and IPL V are ARI certified. All other ratings, including the following, are outside the scope of the certification program and are excluded: • Glycol. • 50 Hz. • Condenserless models CCAF .
5 CG-PRC012-EN Leading in Efficiency and Reliability with State-Of-The-Art Scroll Compressor T echnology Efficiency The energy efficiency of the scroll chiller results in energy costs lower than any other comparable chiller .
CG-PRC012-EN 6 T rane Scroll Compressor — Maximum Efficiency with Enhanced Reliability General The scroll compressor has two scrolls. The top scroll is fixed and the bottom scroll orbits. Each scroll has walls in a spiral shape that intermesh. Inlet-First Orbit As the bottom scroll orbits, two refrigerant gas pockets are formed and enclosed.
7 CG-PRC012-EN Options Hot Gas Bypass: Hot gas bypass option allows unit operation below the minimum step of unit unloading. The regulator valve, along with all associated refrigerant piping and electrical wiring, are factory installed and tested on one refrigeration circuit.
CG-PRC012-EN 8 Controls Human Interfaces The T rane water-cooled 20-60 ton scroll CGWF chiller offers an easy-to-use operator interface panel, the DynaView .
9 CG-PRC012-EN Controls Easy Interface to A Generic Building Management System Controlling the scroll CGWF chiller with building management systems is state- of-the-art, yet simple with either the LonT alk Communications Interface for Chillers (LCI-C) or Generic Building Management System Hardwire Points.
CG-PRC012-EN 10 Controls T racer Summit controls — Interface With The T rane Integrated Comfor t System (ICS) T rane Chiller Plant Control The T racer Summit Chiller Plant Building Management System with Chiller Plant Control provides building automation and energy management functions through stand-alone control.
11 CG-PRC012-EN Controls Keeping Operators Informed A crucial part of efficiently running a chiller plant is assuring that the operations staff is instantly aware of what is happening in the plant.
CG-PRC012-EN 12 Unit Location Units should be installed indoors where exposure to rain or water splash is minimal. A level foundation or flooring must be provided which will support at least 150 percent of the operating weight of the unit. The chiller foundation must be rigid to reduce vibration transmission to a minimum.
