Features and Benefits World Class Energy Efficiency The importance of energy efficiency cannot be understated. Fortunately, ASHRAE has created a guideline emphasizing its importance. Nonetheless, energy is often dismissed as an operational cost over which the owner has little control.That perception results in missed opportunities for energy efficiency, reduced utility bills, and higher profits. Lower utility bills directly affect profitability. Every dollar saved in energy goes directly to the bottom line.
Features and Benefits Condenser coils Trane's condenser coils are manufactured with the same philosophy as the compressors; they're built to last. Even though manufacturing processes have allowed thinner and thinner materials in their assembly, with obvious material and manufacturing savings,Trane's coil material did not change with the RTAC generation of air cooled chillers.
Features and Benefits Unit Performance Testing The AHRI Certification Program has had a certification program covering air-cooled water chillers for many years. With this in mind, customers may ask, "Do I need to factory performance test my chiller?" Trane began promoting factory performance tests for water-cooled water chillers in 1984 for the same reasons it is valid today for air-cooled water chillers, to show we stand behind the products we design and build.
Application Considerations Important Certain application constraints should be considered when sizing, selecting and installingTrane aircooled 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 localTrane sales engineer. Unit Sizing Unit capacities are listed in the performance data section.
Application Considerations temperature or ice making machines.The maximum water temperature that can be circulated through an evaporator when the unit is not operating is 108°F (42°C). Flow Rates Out of Range Many process cooling jobs require flow rates that cannot be met with the minimum and maximum published values for the Model RTAC evaporator. A simple piping change can alleviate this problem. For example: A plastic injection molding process requires 80 gpm (5.
Application Considerations Figure 2. Temperature out of range system layout Variable Flow in the Evaporator An attractive chilled water system option may be a variable primary flow (VPF) system. VPF systems present building owners with several cost saving benefits that are directly related to the pumps.
Application Considerations Staggering the chiller set points is another control technique that works well for preferentially loading Chiller 1. If the cooling load is less than 50 percent of the system capacity, Chiller 1 would be able to satisfy the entire call for cooling. As system loads increase, Chiller 2 is started to meet any portion of the load that Chiller 1 can not meet. Figure 3.
Application Considerations Typical Unit Installation Outdoor HVAC equipment must be located to minimize noise and vibration transmission to the occupied spaces of the building structure it serves. If the equipment must be located in close proximity to a building, it could be placed next to an unoccupied space such as a storage room, mechanical room, etc. It is not recommended to locate the equipment near occupied, sound sensitive areas of the building or near windows.
Application Considerations When electrical demand is high, the ice pump is started and the chiller is either demand limited or shut down completely.Tracer controls have the intelligence to optimally balance the contribution of ice and chiller in meeting the cooling load. The capacity of the chiller plant is extended by operating the chiller and ice in tandem.Tracer rations the ice, augmenting chiller capacity while reducing cooling costs.

Controls LCD Touch Screen Display The standard DynaView display provided with theTrane CH530 control panel features an LCD touch screen that is navigated by file tabs.This is an advanced interface that allows the user to access any important information concerning setpoints, active temperatures, modes, electrical data, pressure, and diagnostics. It uses full text display available in 19 languages.
Controls Stand Alone Controls Single chillers installed in applications without a building management system is simple to install and control: only a remote auto/stop for scheduling is required for unit operation. Signals from the chilled water pump contactor auxiliary, or a flow switch, are wired to the chilled water flow interlock. Signals from a time clock or some other remote device are wired to the external auto/stop input.
Controls LonTalk is a communications protocol developed by the Echelon Corporation.The LonMark association develops control profiles using the LonTalk communication protocol. LonTalk is a unit level communications protocol. LonTalk Communications Interface for Chillers (LCI-C) provides a generic automation system with the LonMark chiller profile inputs/outputs.

Mechanical Specifications General Units are leak and pressure tested at 390 psig high side, 250 psig low side, then evacuated and charged. All Air-Cooled Series R Chillers are factory tested prior to shipment. Packaged units ship with a full operating charge of oil and refrigerant. Unit panels, structural elements and control boxes are constructed of galvanized steel and mounted on a welded structural steel base.
Options include loss of chilled water flow, evaporator freezing, loss of refrigerant, low refrigerant pressure, high refrigerant pressure, reverse rotation, compressor starting and running over current, phase loss, phase imbalance, phase reversal, and loss of oil flow. A digital display indicates chilled water setpoint and leaving chilled water temperature as standard. While current limit setpoint, evaporator and condenser refrigerant pressures, and electrical information are an option.
Options Low Ambient Option The low ambient option provides special control logic, oil coolers, and variable frequency drives on the condenser fan circuits to permit low temperature startup and operation down to 0°F (-18°C). High Ambient Option The high ambient option consists of special control logic and oil coolers to permit high ambient (up to 125°F [51°C]) operation.This option offers the best performance when coupled with the high efficiency performance option.
Options Coil Protection Louvered panels protect the condenser coils only. Compressor Sound Enhancement Factory installed weatherproof compressor enclosure to reduce compressor sound levels. Condenser Corrosion Protection Copper fins and CompleteCoat are available on all size units for corrosion protection. Job site conditions should be matched with the appropriate condenser fin materials to inhibit coil corrosion and ensure extended equipment life.
