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 factoryassembled 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 Model RTHD Options Insulation All low-temperature surfaces are covered with 3/4" (19.05 mm) Armaflex II or equal (K = 0.28) insulation; this includes the evaporator and water boxes, suction line, motor housing, and liquid/vapor separator. 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 Main Power Disconnect Options: Non-fused Disconnect A UL-approved non-fused molded case disconnect switch, factory pre-wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power.
Display 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 eight languages: English, Spanish, Traditional Chinese, Simplified Chinese, Japanese, Portuguese (for Brazil), Korean, and Thai.
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 your Trane Systems Solutions Representative and applying the Trane System Analyzer program.
Selection Procedure Trane Series R chiller performance is rated in accordance with the ARI Standard 550/590-1998 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 The RLA is based on the motor’s performance when reaching full rated horsepower. The kW rating of the motor will equal or exceed the kW requirement indicated by the Series R computer selection program at design conditions. If motor kW draw at design conditions is less than the kW rating of the motor, the RLA at design conditions is determined by multiplying the motor RLA (at the desired voltage) by this ratio: design kW/ motor kW rating.
