Introduction The Trane Model RTAC Air-Cooled Helical-Rotary Chiller is the result of a search for higher reliability, higher energy efficiency, and lower sound levels for today s environment. In an effort to reduce energy consumed by HVAC equipment and to continually produce chilled water, Trane has developed the Model RTAC chiller with higher efficiencies and a more reliable design than any other air-cooled chiller available on the market today. The Model RTAC chiller uses the proven design of the Trane helicalrotary compressor, which embraces all of the design features that have made the Trane helical-rotary compressor liquid chillers such a success since 1987. What Is New The RTAC offers high reliability coupled with greatly improved energy efficiency, vastly reduced physical footprint, and improved acoustical performance, due to its advanced design, low-speed, directdrive compressor, and proven Series R performance. The major advantages of the Series R, Model RTAC are: 99.5% reliability rate Smaller physical footprint Lower sound levels Higher energy efficiency Designed specifically for operating with environmentallysafe HFC-134a. The Series R Model RTAC helicalrotary chiller is an industrial-grade design, built for both the industrial and commercial markets. It is ideal for schools, hospitals, retailers, office buildings, and industrial applications. Figure 1 - Model RTAC size 350 American Standard Inc. 2002

Features and Benefits The Series R Helical-Rotary Compressor Unequaled reliability. The next generation Trane helical-rotary compressor is designed, built, and tested to the same demanding and rugged standards as the Trane scroll compressors, the centrifugal compressors, and the previous generation helicalrotary compressors used in both air- and water-cooled chillers for more than 15 years. Years of research and testing. The Trane helical-rotary compressor has amassed thousands of hours of testing, much of it at severe operating conditions beyond normal commercial airconditioning applications. Proven track record. The Trane Company is the world s largest manufacturer of large helicalrotary compressors used for refrigeration. Over 300,000 compressors worldwide have proven that the Trane helicalrotary compressor has a reliability rate of greater than 99.5% in the first year of operation unequalled in the industry. Resistance to liquid slugging. The robust design of the Series R compressor can ingest amounts of liquid refrigerant that normally would severely damage reciprocating compressor valves, piston rods, and cylinders. Fewer moving parts. The helicalrotary compressor has only two rotating parts: the male rotor and the female rotor. Unlike reciprocating compressors, the Trane helical-rotary compressor has no pistons, connecting rods, suction and discharge valves, or mechanical oil pump. In fact, a typical reciprocating compressor has 15 times as many critical parts as the Series R compressor. Fewer moving parts leads to increased reliability and longer life. Direct-drive, low-speed, semihermetic compressor for high efficiency and high reliability. Field-serviceable compressor for easy maintenance. Suction-gas-cooled motor. The motor operates at lower temperatures for longer motor life. Five minute start-to-start and two minute stop-to-start anti-recycle timer allows for closer water-loop temperature control. 4

Features and Benefits Improved Acoustical Performance Sound levels are reduced significantly by addressing two major sources: the compressor and the refrigerant piping. First, the compressor has been specifically designed to minimize sound generation. Second, the refrigerant components and piping have been optimized to reduce sound propagation throughout the system. Superior Efficiency Levels: The Bar Has Been Raised The standard-efficiency Trane Model RTAC has COP levels up to 2.90 kw/kw [9.9 EER] (including fans), while the premium-efficiency, or high-efficiency, units leap to COP levels of 3.10 kw/kw [10.58 EER] (including fans). The modern technology of the RTAC with the efficient direct-drive compressor, the unique evaporator design, the electronic expansion valve, and the revolutionary Tracer Chiller Controls, has permitted Trane to achieve these efficiency levels, unmatched in the industry. Precise Rotor Tip Clearances Higher energy efficiency in a helicalrotary compressor is obtained by reducing the rotor tip clearances. This next-generation compressor is no exception. With today s advanced manufacturing technology, clearances can be controlled to even tighter tolerances. This reduces the leakage between high- and low-pressure cavities during compression, allowing for more efficient compressor operation. Figure 2 - Cutaway of a compressor Capacity Control and Load Matching The combination patented unloading system on Trane helicalrotary compressors uses the variable unloading valve for the majority of the unloading function. This allows the compressor to modulate infinitely, to exactly match building load and to maintain chilled-water supply temperatures within ± 0.3 C [±0.5 F] of the set point. Reciprocating and helicalrotary chillers that rely on stepped capacity control must run at a capacity equal to or greater than the load, and typically can only maintain water temperature to around ± 1 C [±2 F]. Much of this excess capacity is lost because overcooling goes toward removing building latent heat, causing the building to be dried beyond normal comfort requirements. When the load becomes very low, the compressor also uses a step unloader valve, which is a single unloading step to achieve the minimum unloading point of the compressor. The result of this design is optimized part-load performance far superior to single reciprocating compressors and step-only helical-rotary compressors. 5

Features and Benefits Compact Physical Size The Trane Model RTAC 120 to 200 chiller averages a 20% reduction in physical footprint, 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. All physical sizes were changed without sacrificing the side clearances needed to supply fresh airflow without coil starvation the tightest operational clearances in the industry. Close Spacing Installation The air-cooled Series R chiller has the tightest recommended side clearance in the industry, 1.2 meters, but that is not all. In situations where equipment must be installed with less clearance than recommended, which frequently occurs in retrofit applications, restricted airflow is common. Conventional chillers may not work at all. However, the air-cooled Series R chiller with the Adaptive Control microprocessor will make as much chilled water as possible given the actual installed conditions, stay online during any unforeseen abnormal conditions, and optimize its performance. Consult your sales engineer for more details. Factory Testing Means Trouble-Free Start-up All air-cooled Series R chillers are given a complete functional test at the factory. This computer-based test program completely checks the sensors, wiring, electrical components, microprocessor function, communication capability, expansion valve performance, and fans. In addition, each compressor is run-tested to verify capacity and efficiency. Where applicable, each unit is factory preset to the customer s design conditions. An example would be the leavingliquid temperature set point. The result of this test program is that the chiller arrives at the job site fully tested and ready for operation. Factory-Installed and Tested Controls and Options Speed Installation All Series R chiller options, including main power-supply disconnect, low ambient control, ambient temperature sensor, low ambient lockout, communication interface and ice-making controls are factory installed and tested. Some manufacturers send accessories in pieces to be field installed. With Trane, the customer saves on installation expense and has assurance that ALL chiller controls and options have been tested and will function as expected. 6

Features and Benefits Figure 3 - Ice storage demand cost savings LOAD MN 6 A.M. NOON 6 P.M. MN ICE CHILLER Superior Control with Tracer Chiller Controls 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 does not nuisance-trip or unnecessarily shut down. Only when the Tracer chiller controls have exhausted all possible corrective actions, and the unit is still violating an operating limit, will the chiller shut down. Controls on other equipment typically shut down the chiller, usually just when it is needed the most. For Example: A typical five-year-old chiller with dirty coils might trip out on highpressure cutout on a 38 C [100 F] day in August. A hot day is just when comfort cooling is needed the most. In contrast, the air-cooled Series R chiller with an Adaptive Control microprocessor will stage fans on, modulate the electronic expansion valve, and modulate the slide valve as it approaches a highpressure cutout, thereby keeping the chiller on line when you need it the most. System Options: Ice Storage Trane air-cooled chillers are wellsuited for ice production. The unique ability to operate at decreased ambient temperature while producing ice results in approximately the same amount of work for the compressor. An aircooled machine typically switches to ice production at night. Two things happen under this assumption. First, the leaving brine temperature from the evaporator is lowered to around -5.5 to -5 C [22 to 24 F]. Second, the ambient temperature has typically dropped about 8.3 to 11 C [15 to 20 F] from the peak daytime ambient. This effectively places a lift on the compressors that is similar to daytime running conditions. The chiller can operate in lower ambient at night and successfully produce ice to supplement the next day s cooling demands. The Model RTAC produces ice by supplying ice storage tanks with a constant supply of glycol solution. Air-cooled chillers selected for these lower leaving-fluid temperatures are also selected for efficient production of chilled fluid at nominal comfort-cooling conditions. The ability of Trane chillers to serve double duty in ice production and comfort cooling greatly reduces the capital cost of ice-storage systems. When cooling is required, ice-chilled glycol is pumped from the ice storage tanks directly to the cooling coils. No expensive heat exchanger is required. The glycol loop is a sealed system, eliminating expensive annual chemical treatment costs. The air-cooled chiller is also available for comfortcooling duty at nominal cooling conditions and efficiencies. The modular concept of glycol icestorage systems, and the proven simplicity of Trane Tracer controls, allow the successful blend of reliability and energy-saving performance in any ice-storage application. The ice-storage system is operated in six different modes, each optimized for the utility cost at a particular time of day. 1. Provide comfort cooling with chiller 2. Provide comfort cooling with ice 3. Provide comfort cooling with ice and chiller 4. Freeze ice storage 5. Freeze ice storage when comfort cooling is required 6.Off 7

Features and Benefits Tracer optimization software controls operation of the required equipment and accessories to easily move from one mode of operation to another. For example: even with ice-storage systems, there are numerous hours when ice is neither produced nor consumed, but saved. In this mode, the chiller is the sole source of cooling. For example, to cool the building after all ice is produced but before high electric aldemand charges take effect, Tracer sets the air-cooled chiller leavingfluid set point to its most efficient setting and starts the chiller, chiller pump, and load pump. 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 the ice and the 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. When ice is produced, Tracer will lower the air-cooled chiller leaving-fluid set point and start the chiller, ice and chiller pumps, and other accessories. Any incidental loads that persists while producing ice can be addressed by starting the load pump and drawing spent cooling fluid from the ice storage tanks.

The current-carrying parts are shrouded in order to prevent accidental contact. 9

Application Considerations Figure 4 - GPM Out of Range 10 C 7.6 L/s 13.7 C 7.6 L/s CV pump 7.5 L/s 10 C 2.5 L/s Important Certain application constraints should be considered when sizing, selecting, and installing Trane aircooled Series R chillers. Unit and system reliability is often dependent on properly and completely complying with these considerations. When the application varies from the guidelines presented, it should be reviewed with your local sales engineer. Unit Sizing Unit capacities are listed in the performance data section. Intentionally oversizing a unit to ensure adequate capacity is not recommended. Erratic system operation and excessive compressor cycling are often a direct result of an oversized chiller. In addition, an oversized unit is usually more expensive to purchase, install, and operate. If oversizing is desired, consider using two units. Water Treatment Dirt, scale, products of corrosion, and other foreign material will adversely affect heat transfer between the water and system components. Foreign matter in the chilled-water system can also increase pressure drop and, consequently, reduce water flow. Proper water treatment must be determined locally, depending on the type of system and local water characteristics. Neither salt nor brackish water is recommended for use in Trane air-cooled Series R 10 C 5 L/s 15.6 C 5 L/s CV Pump 5 L/s Load chillers. Use of either will lead to a shortened chiller life. Trane encourages the employment of a reputable water-treatment specialist, familiar with local water conditions, to assist in this determination and in the establishment of a proper watertreatment program. Effect of Altitude on Capacity Air-cooled Series R chiller capacities given in the performance data tables are for use at sea level. At elevations substantially above sea level, the decreased air density will reduce condenser capacity and, therefore, unit capacity and efficiency. Ambient Limitations Trane air-cooled Series R chillers are designed for year-round operation over a range of ambient temperatures. The air-cooled Model RTAC chiller will operate in ambient temperatures of 0 to 46 C [32 to 115 F]. Selecting the high-ambient option will allow the chiller to operate in ambient temperatures of 52 C [125 F], and selecting the lowambient option will increase the operational capability of the water chiller to ambient temperatures as low as -18 C [0 F]. For operation outside of these ranges, contact the local sales office. Water Flow Limits The minimum water flow rates are given in Tables G1 - G16. flow rates below the tabulated values will result in laminar flow and cause freeze-up problems, scaling, stratification, and poor control. The maximum evaporator water flow rate is also given in the general data section. Flow rates exceeding those listed may result in excessive tube erosion. Flow Rates Out of Range Many process cooling jobs require flow rates that cannot be met with the minimum and maximum published values within the Model RTAC evaporator. A simple piping change can alleviate this problem. For example: a plastic injection molding process requires 5.0 L/s [80 gpm] of 10 C [50 F] water and returns that water at 15.6 C [60 F]. The selected chiller can operate at these temperatures, but has a minimum flow rate of 7.6 L/s [120 gpm]. The following system can satisfy the process. Flow Control Trane requires the chilled water flow control in conjunction with the Air- Cooled Series R Chiller to be done by the chiller. This will allow the chiller to protect itself in potentially harmful conditions. 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 4.4 to 15.6 C [40 to 60 F]. Low-temperature machines produce leaving-liquid temperatures less than 4.4 C [40 F]. Since liquid supply temperature set points less than 4.4 C [40 F] result in suction temperatures at or below the freezing point of water, a glycol solution is required for all lowtemperature machines. Ice-making machines have a leaving-liquid temperature range of -6.7 to 15.6 C [20 to 60 F]. Ice-making controls include dual set point controls and safeties for ice making and standard cooling capabilities. Consult your local sales engineer for applications or selections involving low temperature or ice making machines. The maximum water temperature that can be circulated through an evaporator when the unit is not operating is 42 C [108 F]. 10

Application Considerations Figure 5 - Temperature Out of Range 15.6 C 7.6 L/s 21 C 7.6 L/s 15 C 5.4 L/s CV Pump 15.6 C 2.2 L/s 35 C 2.2 L/s Leaving-Water Temperature Out of Range Many process cooling jobs require temperature ranges 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 laboratory load requires 7.6 L/s [120 gpm] of water entering the process at 29.4 C [85 F] and returning at 35 C [95 F]. The accuracy required is higher than the cooling tower can give. The selected chiller has adequate capacity, but has a maximum leaving-chilled-water temperature of 15.6 C [60 F]. In the example shown, both the chiller and process flow rates are equal. This is not necessary. For example, if the chiller had a higher flow rate, there would be more water bypassing and mixing with warm water. Supply-Water Temperature Drop The performance data for the Trane air-cooled Series R chiller is based on a chilled-water temperature drop of 6 C [10.8 F]. Chilled-water temperature drops from 3.3 to 10 C [6 to 18 F] may be used as long as minimum and maximum water temperature, and minimum and maximum flow rates, are not violated. Temperature drops outside this range are beyond the optimum range for control, and may adversely affect the microcomputer s ability to maintain an acceptable supply-water temperature range. Further, 35 C 5.4 L/s CV Pump 35 C 7.6 L/s 29.4 C 7.6 L/s Load temperature drops of less than 3.3 C [6 F] may result in inadequate refrigerant superheat. Sufficient superheat is always a primary concern in any direct-expansion refrigerant system and is especially important in a package chiller where the evaporator is closely coupled to the compressor. When temperature drops are less than 3.3 C [6 F], an evaporator runaround loop may be required. Variable Flow in the 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. The most obvious cost savings result from eliminating the secondary distribution pump, which in turn avoids the expense incurred with the associated piping connections (material, labor), electrical service, and variable-frequency drive. Building owners often cite pumprelated energy savings as the reason that prompted them to install a VPF system. With the help of a software analysis tool such as System Analyzer, TRACE, or DOE-2, you can determine whether the anticipated energy savings justify the use of variable primary flow in a particular application. It may also be easier to apply variable primary flow in an existing chilledwater plant. Unlike the decoupled design, the bypass can be positioned at various points in the chilled-water loop and an additional pump is unnecessary. The evaporator in the Model RTAC can withstand up to 50 percent water flow reduction as long as this flow is equal to or above the minimum flow-rate requirements. The microprocessor and capacity control algorithms are designed to take a maximum of 10 percent change in water flow rate per minute. 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. If the chiller is unable to operate, one or two days of ice may still be available to provide cooling. In that period of time, the chiller can be repaired before building occupants feel any loss of comfort. The Trane Model RTAC chiller is uniquely suited to low-temperature applications like ice storage because of the ambient relief experienced at night. This allows the Model RTAC chiller to produce ice efficiently, with less stress on the machine. Simple and smart control strategies are another advantage the Model RTAC chiller offers for ice-storage applications. Trane Tracer building management systems can actually anticipate how much ice needs to be made at night, and operate the system accordingly. The controls are integrated right into the chiller. Two wires and preprogrammed software dramatically reduce field installation cost and complex programming. 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 returnwater temperature. If there is not a sufficient volume of water in the system to provide an adequate 11

Application Considerations buffer, temperature control can be lost, resulting in erratic system operation and excessive compressor cycling. A short water loop has the same effect as attempting to control using the building return water. Typically, a two-minute water loop is sufficient to prevent a short water loop. Therefore, as a guideline, ensure that the volume of water in the evaporator loop equals or exceeds two times the evaporator flow rate per minute. For a rapidly changing load profile, the amount of volume should be increased. To prevent the effect of a short water loop, the following item should be given careful consideration: a storage tank or larger header pipe to increase the volume of water in the system and, therefore, reduce the rate of change of the return water temperature. Applications Types Comfort cooling Industrial process cooling Ice or thermal storage Low-temperature process cooling. 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. Locating the equipment away from structures will also prevent sound reflection, which can increase levels at property lines, or other sensitive points. When physically isolating the unit from structures, it is a good idea to not use rigid supports, and to eliminate any metal-to-metal or hard material contact, when possible. This includes replacing spring or metal weave isolation with elastomeric isolators. Figure 6 illustrates isolation recommendations for the RTAC. Figure 6 - Unit isolation recommendations 12

Selection Procedure The chiller capacity tables cover the most frequently encountered leaving-liquid temperatures. The tables reflect a 6 C [10.8 F] temperature drop through the evaporator. For other temperature drops, apply the appropriate performance data adjustment factors. For chilled brine selections, contact your local sales office. To select a Trane air-cooled Series R chiller, the following information is required: Selection Procedure SI Units 1 Design load in kw of refrigeration 2 Design chilled-water temperature drop 3 Design leaving-chilled-water temperature 4 Design ambient temperature flow rates can be determined by using the following formula: L/s = kw (capacity) x 0.239 temperature drop ( C) To determine the evaporator pressure drop we use the flow rate (L/s) and the evaporator water pressure drop Figure P-1. 5 The final unit selection is: Quantity (1) RTAC 140 Cooling capacity = 492.9 kw Design ambient temperature 35 C Entering chilled-water temperatures = 12 C Leaving chilled-water temperatures = 7 C Chilled-water flow rate = 23.51 L/s water pressure drop = 37 kpa Compressor power input = 159.3 kw Unit COP = 2.85 kw/kw Contact the local sales engineer for a proper selection at the given operating conditions.

Controls Figure 7 - Easy View Figure 8 - Dyna View Safety Controls A centralized microcomputer offers a higher level of machine protection. Because the safety controls are smarter, they limit compressor operation in order to avoid compressor or evaporator failures, thereby minimizing nuisance shutdowns. Tracer Chiller Controls directly senses the control variables that govern the operation of the chiller: motor current draw, evaporator pressure, condenser pressure. When any one of these variables approaches a limit condition at which the unit may be damaged or shut down on a safety, Tracer Chiller Controls takes corrective action to avoid shutdown and keep the chiller operating. It does this through combined actions of compressor slide-valve modulation, electronic expansionvalve modulation, and fan staging. Tracer Chiller Controls optimizes total chiller power consumption during normal operating conditions. During abnormal operating conditions, the microprocessor will continue to optimize chiller performance by taking the corrective action necessary to avoid shutdown. This keeps cooling capacity available until the problem can be solved. Whenever possible, the chiller is allowed to perform its function: make chilled water. In addition, microcomputer controls allow for more types of protection, such as over and under voltage! (option) Overall, the safety controls help keep the building or process running and out of trouble. Stand-alone controls Interfacing to stand-alone units is very simple: 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. Tracer Chiller Control human interfaces The Trane air-cooled Series R Model RTAC chiller offers two easy-to-use operator interface panels, the EasyView, and the DynaView. Standard Features External Auto/Stop A job-site-provided contact closure will turn the unit on and off. Chilled Waterflow Interlock A job-site-provided contact closure from a chilled-water pump contactor, or a flow switch, is required and will allow unit operation if a load exists. This feature will allow the unit to run in conjunction with the pump system. External Interlock A job-site-provided contact opening wired to this input will turn the unit off and require a manual reset of the unit microcomputer. This closure is typically triggered by a job-siteprovided system such as a fire alarm. Chilled Water Pump Control Unit controls provide an output to control the chilled-water pump(s). One contact closure to the chiller is all that is required to initiate the chilled-water system. Chilled water pump control by the chiller is a requirement on all the Air-Cooled Series R Chillers. 42

Controls Alarm Indication Contacts Four factory-installed contacts with the following preset default assignments: Alarm Chiller running Maximum capacity Chiller limit. Additional Features that May Be Added (require some optional factoryinstalled hardware) Ice-making card Tracer communication card Chilled water and remote currentlimit set point card. Note: All wiring outside the unit is supplied at the job site. 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. This means you have the flexibility to meet job requirements while not having to learn a complicated control system. This setup has the same standard features as a stand-alone water chiller, with the possibility of having additional optional features. What are LonTalk, Echelon, and LonMark? 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, unlike BACNet used at the system level. LonTalk Communications Interface for Chillers (LCI-C) LonTalk Communications Interface for Chillers (LCI-C) provides a generic automation system with the LonMark chiller profile inputs/outputs. The inputs/ outputs include both mandatory and optional network variables. Note: LonMark network variable names are in parentheses when different from chiller naming convention. Chiller Inputs: Chiller Enable/Disable Chilled Liquid Setpoint (Cool Setpoint) Current Limit Setpoint (Capacity Limit Input) Ice Making (Chiller Mode) Chiller Enable/Disable Allows for chiller to be started or stopped depending on if certain operating conditions are met. Chilled Liquid Setpoint Allows for the external setting independent of the front panel setpoint to adjust the leaving water temperature setpoint. Current Limit Setpoints Allows for the external setting independent of the front panel setpoint to limit the capacity level of the chiller. Ice Making Provides interface with ice making control systems. Please refer to page 9 for more information. Chiller Outputs: On/Off o Active Setpoint Average Percent RLA (Actual Capacity Level) Active Current Limit Setpoint (Capacity Limit) Leaving Chilled Water Temperature Entering Chilled Water Temperature Alarm Descriptor Chiller Status 43

The input/outputs are as follows: Chiller hardwire inputs include: Chiller enable/disable Circuit enable/disable External chilled water setpoint - option External current limit setpoint - option Ice making enable - option External Chilled Water Setpoint - option Allows the external setting independent of the front panel setpoint by one of two means: a) 2-10 VDC input, or b) 4-20 ma input External Current Limit Setpoint - option Allows the external setting independent of the front panel setpoint by one of two means: a) 2-10 VDC input, or b) 4-20 ma input Chiller hardwire outputs include: Compressor running indication Alarm indication (Ckt1/Ckt 2) Maximum capacity Ice making status Alarm Indication Contacts The unit provides three single-pole/ double-throw contact closures to indicate: a) Compressor on/off status b) Compressor running at maximum capacity c) Failure has occurred (Ckt 1/Ckt 2) These contact closures may be used to trigger jobsite supplied alarm lights or alarm bells. Ice Making Control - option Provides interface with ice making control systems. 44

Controls Tracer Summit Controls Interface with the Trane Integrated Comfort System (ICS) Trane Chiller Plant Control The Tracer Chiller Plant Manager building management system provides building automation and energy management functions through stand-alone control. The Chiller Plant Control is capable of monitoring and controlling your entire chiller plant system. Application software available: Time-of-day scheduling Demand limiting Chiller sequencing Process control language Boolean processing Zone control Reports and logs Custom messages Run time and maintenance Trend log PID control loops And of course, the Trane Chiller Plant Control can be used on a stand-alone basis or tied into a complete building automation system. When the air-cooled Series R chiller is used in conjunction with a Trane Tracer Summit system, the unit can be monitored and controlled from a remote location. The air-cooled Series R chiller can be controlled to fit into the overall building automation strategy by using time-of-day scheduling, timed override, demand limiting, and chiller sequencing. A building owner can completely monitor the air-cooled Series R chiller from the Tracer system, since all of the monitoring information indicated on the microcomputer can be read on the unit controllers Tracer system display. In addition, all the powerful diagnostic information can be read back at the Tracer system. Best of all, this powerful capability comes over a single twisted pair of wires! Air-cooled Series R chillers can interface with many different external control systems, from simple stand-alone units to icemaking systems. Each unit requires a single-source, three-phase power supply and a 115-volt power supply. The 115-volt supply handles the freeze protection for the evaporator heaters. A single twisted pair of wires tied directly between the air-cooled Series R chiller and a Tracer Summit system provides control, monitoring, and diagnostic capabilities. Control functions include auto/stop, adjustment of leaving-water-temperature set point, compressor operation lockout for kw demand limiting, and control of ice-making mode. The Tracer system reads monitoring information such as entering- and leaving-evaporatorwater temperatures and outdoor air temperature. Over 60 individual diagnostic codes can be read by the Tracer system. In addition, the Tracer system can provide sequencing control for up to 25 units on the same chilled-water loop. Pump sequencing control can be provided from the Tracer system. Tracer ICS is not available in conjunction with the external set point capability. Required Options 1 Tracer Interface Additional Options that May Be Used Ice-Making Control External Trane Devices Required Tracer Summit, Tracer 100 System or Tracer Chiller Plant Control 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 icemaking mode, the air-cooled Series R chiller will operate at full compressor capacity until the return chilled-fluid temperature entering the evaporator meets the icemaking set point. Two input signals are required to the air-cooled Series R chiller for the ice-making option. The first is an auto/stop signal for scheduling, and the second is required to switch the unit between the ice-making mode and normal daytime operation. The signals are provided by a remote job site building-automation device such as a time clock or a manual switch. In addition, the signals may be provided over the twisted wire pair from a Tracer system, or a LonTalk Communication Interface but will require the communication boards provided with the Ice Making Control Option. Additional Options That May Be Used Failure Indication Contacts Communications Interface (For Tracer Systems) Chilled-Water Temperature Reset 45

Water connections are grooved pipe for Victaulic couplings. Each shell includes a vent, a drain, and fittings for temperature control sensors, and is insulated with 19mm [3/4 inch] Armaflex II (or equivalent) insulation (K=0.26). heaters with thermostats are provided to protect the evaporator from freezing at ambient temperatures down to -29 C [20 F]. Condenser and Fans Air-cooled condenser coils have aluminum fins mechanically bonded to internally-finned seamless copper tubing. The condenser coil has an integral subcooling circuit. Condensers are factory proof- and leak-tested at 35 bars [500 psi]. Direct-drive vertical-discharge airfoil ZephyrWing condenser fans are dynamically balanced. Three-phase condenser fan motors with permanently-lubricated ball bearings are provided. Standard units will start and operate from 0 to 46 C [32 to 115 F] ambient. (High ambient option above 40 C). Compressor and Lube Oil System The helical-rotary compressor is semi-hermetic, direct drive, 3000 rpm, with capacity-control slide valve, a load/unload valve, rolling element bearings, differential refrigerant pressure oil pump, and oil heater. The motor is a suctiongas-cooled, hermetically sealed, two-pole squirrel-cage induction motor. Oil separator and filtration devices are provided separate from the compressor. Check valves in the compressor discharge and lube oil system, and a solenoid valve in the lube system, are provided. Refrigeration Circuits Each unit has two refrigerant circuits, with one or two helicalrotary compressors per circuit. Each refrigerant circuit includes a mechanical filter, liquid-line shutoff valve, liquid-line sight glass, charging port, and an electronic expansion valve. Fully modulating compressors and electronic expansion valves provide variable capacity modulation over the entire operating range. (Optional compressor suction service valve). Unit Controls All unit controls are housed in a weather-tight enclosure, with removable plates to allow for customer connection of power wiring and remote interlocks. All controls, including sensors, are factory-mounted and tested prior to shipment. Microcomputer controls provide all control functions including startup and shutdown, leaving-chilled-water temperature control, compressor and electronic expansion-valve modulation, fan sequencing, anti-recycle logic, automatic lead/lag compressor starting, and load limiting. The unit control module, utilizing the Adaptive Control microprocessor, automatically takes action to avoid unit shutdown due to abnormal operating conditions associated with low refrigerant pressure, high condensing pressure, and motor current overload. Should the abnormal operating condition continue until a protective limit is violated, the unit will be shut down. Unit protective functions include loss of chilled-water flow, evaporator freezing, loss of refrigerant, low refrigerant pressure, high refrigerant pressure, reverse rotation, compressorstarting and -running overcurrent, phase loss, phase imbalance, phase reversal, and loss of oil flow. The Easy View digital display indicates the chilled-water set point and the leaving-chilled-water temperature. 55

Mechanical Specifications In addition, the Dyna View indicates the current limit set point, the evaporator and condenser refrigerant pressures, and electrical information. Both standard and optional displays can be viewed on the unit without opening any control panel doors. Standard power connections include main three-phase power to the compressors, condenser fans, control power transformer, and freeze protection on the evaporator heaters. Starters Starters are housed in a weathertight enclosure with hinged doors to allow for customer connection of power wiring. Wye-Delta closed transition starters (33% of LRA inrush) are standard. 56
