Air-Cooled Series R Rotary Liquid Chiller ™ Model RTAC 140 to 500 Tons (60 Hz) 140 to 400 Tons (50 Hz) Built For the Industrial and Commercial Markets August 2002 RLC-PRC006-EN
Introduction You… Figure 1 — Cutaway of RTAC Air-Cooled Chiller Like its chillers, Trane wants its relationships with customers to last. Trane is interested in maintaining long term, loyal relationships. This perspective means the point in time that a customer purchases a chiller is the beginning of a relationship, not the end. Your business is important, but your satisfaction is paramount. 4 Designed by Customers…. 1 Trane’s RTAC was designed with the end user’s requirements in mind.

Features and Benefits Figure 2 — Cutaway of a compressor Excellent Reliability… A buildings environment is expected to be comfortable. When it is, no one says a word. If it’s not… that’s a different story. The same is true with chillers. No one ever talks about chillers, yet alone compressors, until they fail, and tenants are uncomfortable and productivity is lost. Trane’s helical rotary compressors have a first year reliability rate of over 99%, which means our chillers stay running when you need them.
Features and Benefits Simple Installation • Compact Physical Size. The Trane Model RTAC chiller averages a 20% reduction in physical footprint, while the greatest change is actually 40% smaller when compared against the previous design. This improvement makes the RTAC the smallest air-cooled chiller in the industry and a prime candidate for installations that have space constraints.
Features and Benefits Superior Control with Tracer™ Chiller Controllers The Adaptive Control™ microprocessor system enhances the air-cooled Series R chiller by providing the very latest chiller control technology. With the Adaptive Control microprocessor, unnecessary service calls and unhappy tenants are avoided. The unit is designed not to trip or unnecessarily shut down.
Features and Benefits High Efficiency/Performance Option This option provides oversized heat exchangers for two purposes. One, it allows the unit to be more energy efficient. Two, the unit will have enhanced operation in high ambient conditions. Access Protection A coated wire mesh that covers the access area under the condenser coils. Low Temperature Brine The hardware and software on the unit are factory set to handle low temperature brine applications (less than 40°F/4.4°C).
Application Considerations Important Certain application constraints should be considered when sizing, selecting and installing Trane air-cooled Series R chillers. Unit and system reliability is often dependent upon proper and complete compliance with these considerations. When the application varies from the guidelines presented, it should be reviewed with your local Trane sales engineer. Unit Sizing Unit capacities are listed in the performance data section.
Application Considerations Leaving Water Temperature Limits Trane air-cooled Series R chillers have three distinct leaving water categories: standard, low temperature, and ice making. The standard leaving solution temperature range is 40 to 60°F/4.4 to 15.6°C. Low temperature machines produce leaving liquid temperatures less than 40°F/4.4°C. Since liquid supply temperature setpoints less than 40°F/4.
Application Considerations Ice Storage Provides Reduced Electrical Demand An ice storage system uses a standard chiller to make ice at night when utilities charge less for electricity. The ice supplements or even replaces mechanical cooling during the day when utility rates are at their highest. This reduced need for cooling results in big utility cost savings. Another advantage of ice storage is standby cooling capacity.
Application Considerations Short Water Loops The proper location of the temperature control sensor is in the supply (outlet) water connection or pipe. This location allows the building to act as a buffer and assures a slowly changing return water temperature. If there is not a sufficient volume of water in the system to provide an adequate buffer, temperature control can be lost, resulting in erratic system operation and excessive compressor cycling.
Selection Procedure The chiller capacity tables cover the most frequently encountered leaving liquid temperatures. The tables reflect a 10°F/5.6°C temperature drop through the evaporator. For other temperature drops, apply the appropriate Performance Data Adjustment Factors from Table A-1. For chilled brine selections, contact your local Trane sales engineer.

Human Interfaces The Trane air-cooled Model RTAC chiller offers two easy-to-use operator interface panels, the EasyView and the DynaView. Controls Standalone Controls Figure C1 — DynaView Operator Interface Standard Features • External Auto/Stop — A jobsite provided contact closure will turn the unit on and off. EasyView is a coded display that allows the user to access the current leaving water temperature, its setpoint, and any recent diagnostics.
Controls Easy Interface to A Generic Building Management System Controlling the air-cooled Series R chiller with building management systems is state-of-the-art, yet simple with either the LonTalk Communications Interface for Chillers (LCI-C) or Generic Building Management System Hardwire Points. Simple Interface with Other Control Systems Microcomputer controls afford simple interface with other control systems, such as time clocks, building automation systems, and ice storage systems.

Controls Ice Making Systems Controls An ice making option may be ordered with the air-cooled Series R™ chiller. The unit will have two operating modes, ice making and normal daytime cooling. In the ice making mode, the air-cooled Series R chiller will operate at full compressor capacity until the return chilled fluid temperature entering the evaporator meets the ice making setpoint. This ice making setpoint is manually adjusted on the unit’s microcomputer.
