Features and Benefits Application Versatility and High Performance • Screw compressor technology and the electronic expansion valve provide reliable performance in an expanded range of operating temperatures. •Tight water temperature control extends to operation of multiple chillers in parallel or series configurations, offering further system design flexibility for maximum efficiency. • Advanced design enables chilled water temperature control to +/- 0.5°F (.
Features and Benefits State-of-the-Art, Precision Control • Microprocessor-based CH530 controls monitor and maintain optimal operation of the chiller and its associated sensors, actuators, relays, and switches, all of which are factory-assembled and extensively tested. • Easy interface with computers hosting Tracer Summit™ building automation/ energy management systems allows the operator to efficiently optimize comfort system performance and minimize operating costs.
Options Insulation All low temperature surfaces are covered with factory installed 3/4 inch (19.05 mm) Armaflex II or equal (k=0.28) insulation, including the evaporator and water boxes, suction line, and motor housing. 3/8" foam insulation is used on the liquid level sensor and gas pump assembly, including piping. Low-Temperature Evaporator Addition of an oil cooler to the oil circuit enables evaporator operation down to minimum leaving water temperature of 10°F (-12.2°C).
Options Control Options: Tracer Summit Communications Link to factory-installed, tested communication board, via single twistedpair wiring, addsTracer Summit communications to the system. LonTalk LCI-C Interface LonTalk (LCI-C) communications capabilities are available, with communication link via single twisted-pair wiring to factory-installed, tested communication board.
Controls LCD Touch-Screen Display with Multi-Language Support The standard DynaView display provided with the CH530 control panel features an LCD touch-screen, allowing access to all operational inputs and outputs.This display supports eleven languages: English, Chinese, Dutch, French, German, Italian, Japanese, Korean, Portugese, Spanish andThai.
Controls Trane Chiller Plant Automation Trane’s depth of experience in chillers and controls makes us a well-qualified choice for automation of chiller plants using aircooled Series R® chillers®.The chiller plant control capabilities of theTraneTracer Summit® building automation system are unequaled in the industry. Our chiller plant automation software is fully preengineered and tested.
Application Considerations Condenser Water Temperatures Reduced sensitivity to condenser water startup temperatures is one major enhancement in the newest-generation water-cooled Series R chiller. With the model RTHD chiller, a condenser water control method is necessary only if the unit starts with entering water temperatures below 55°F (12.8°C), or between 45°F (7.2°C) and 55°F (12.8°C), when a temperature increase of 1°F (0.56°C) per minute to 55°F (12.8°) is not possible.
Application Considerations Series Chiller Arrangements Another energy-saving strategy is to design the system around chillers arranged in series, on the evaporator, condenser, or both.The actual savings possible with such strategies depends on the application dynamics and should be researched by consulting yourTrane Systems Solutions Representative and applying theTrane System Analyzer program.
Selection Procedure Trane Series R chiller performance is rated in accordance with the ARI Standard 550/590-2003 Certification Program. Chiller selection assistance and performance information can be obtained by using the Series R chiller selection program, available through local Trane sales offices. Performance The computerized Series R chiller selection program provides performance data for each possible chiller selection at both full-load and part-load design points, as required.
Selection Procedure Unit Performance with Fluid Media Other Than Water Series R chillers can be provided with a wide variety of fluid media other than water, including ethylene glycol and propylene glycol— in the evaporator, condenser or both. Chillers using media other than water are excluded from the ARI 550/590-2003 Certification Program, but are rated in accordance with ARI Standard 550/590-2003. Trane factory performance tests are only performed with water as the cooling and heatrejection media.
