T rane provides laboratory-grade, calibrated performance testing on ARI approved test loops that proves the performance of the chiller tailored to your application.
11 CTV -PRC007-EN Design Simplicity Impellers are keyed directly to the motor shaft for high reliability and performance and low life-cycle costs. Reliable Motor Cooling The motor is engulfed in liquid refrigerant to provide efficient, complete cooling at all load conditions.
CTV -PRC007-EN 12 CenT raV ac ™ Three-Stage P-H Diagram The pressure-enthalphy (P-H) diagram describes refrigerant flow through the major CVHE/CVHG chiller components. This diagram confirms the superior operating cycle efficiency of the three- stage compressor and two-stage economizer .
13 CTV -PRC007-EN Unit Options Unit-Mounted Starters T rane factory installed options make installation of a CenT raV ac ™ chiller easier , faster and less costly .
CTV -PRC007-EN 14 Figure O-2 – T ypical Equipment Room Layout – Unit-Mounted Star-Delta Starter Figure O-1 – T ypical Equipment Room Layout – Conventional Remote Star -Delta Starter • System Design T ime Cost Savings System design time is reduced, since all starter components and interconnecting wiring are pre- engineered and selected.
15 CTV -PRC007-EN The solid-state starter controls the starting characteristics of a motor by controlling the current that flow to the motor . It does so through the use of SCRs (Silicon Controlled Rectifiers), which are solid-state switching devices, and an integral bypass contactor for power control.
CTV -PRC007-EN 16 Unit Options Adaptive Frequency Drives Figure O-4 — CVHE500 Part Load Efficiencies with/without AFD Benefits T rane Adaptive Frequency drives* provide motor control, but they are much more than just starters.
17 CTV -PRC007-EN Condenser water temperature relief of chilled water reset Compressor lift reduction is required for a chiller application, both to provide stable chiller operation at part-loads and to achieve greater energy savings.
CTV -PRC007-EN 18 Benefits The T rane patented free cooling accessory for T rane CenT raV ac ™ chillers adapts the basic chiller so it may function as a simple heat exchanger using refrigerant as the working fluid.
19 CTV -PRC007-EN Free Cooling Unit Options T emperature and humidity control requirements are important considerations when evaluating the use of CenT raV ac free cooling. Low temperature outside air (from the outside air economizer) often requires a large amount of energy for humidification purposes.
CTV -PRC007-EN 20 System Options Auxiliary Condenser Auxiliary Condenser The T rane auxiliary condenser provides economical heat recovery for applications with small heating demand. It ’ s well-suited to preheat applications including domestic hot water , boiler makeup water and swimming pools.
21 CTV -PRC007-EN System Options Auxiliary Condenser (Cont.) Controls The auxiliary condenser was designed for simplicity of operation. Machine load, water flow rate, and temperature determine the amount of heat recovered.
CTV -PRC007-EN 22 Ice Storage Provides Reduced Electrical Demand Ice storage is the hottest thing in cooling today . It has been accepted by building owners and tenants who are concerned about utility costs. An ice storage system uses a standard chiller to make ice at night when utilities charge less for electricity .
23 CTV -PRC007-EN Heat Recovery System Options Heat Recovery Use of the Heat Recovery CenT raV ac ™ can significantly reduce the energy operating costs of many buildings by using heat which normally would be rejected to the atmosphere.
CTV -PRC007-EN 24 Simultaneous Heating and Cooling The T rane Heat Recovery CenT raV ac ™ chiller is an excellent choice for applications requiring simultaneous heating and cooling.
25 CTV -PRC007-EN System Options Chilled W ater Reset Chilled W ater Reset — Chilled water reset is often a practical means of reducing energy consumption during periods of the year when heating loads are high but cooling loads are reduced. Resetting the chilled water temperature increases the evaporator refrigerant pressure.
CTV -PRC007-EN 26 For Applications Requiring 1300-3500 T ons (60 Hz), Choose LHCV • The LHCV chiller system is the modern solution for large central plant applications. It offers significant first cost and operating cost advantages compared to field-assembled very large chillers.
27 CTV -PRC007-EN Condenser Water Limitations T rane CenT raV ac ™ chillers start and operate over a range of load conditions with controlled water temperatures. Reducing the condenser water temperature is an effective method of lowering the chiller power input.
CTV -PRC007-EN 28 Selection The CenT raV ac ™ centrifugal chiller product line provides more than 200,000 individual unit selections over a capacity range of 170 through 3500 tons.

33 CTV -PRC007-EN Controls Advanced Controls T rane set the standard for unit microprocessor controls in 1985 with the first generation Unit control panel.
CTV -PRC007-EN 34 Controls Building Automation and Chiller Plant Control For building automation and control of chilled water plants, T rane has developed the T racer Summit ™ . It can control the operation of the complete installation: chillers, pumps, cooling towers, isolating valves, air handlers and terminal units.
35 CTV -PRC007-EN Controls Optimal Performance Regardless of the system level being designed, the unit controls become critical not just in making every level operate reliably but in facilitating optimal performance.
CTV -PRC007-EN 36 • Evaporator leaving fluid temperature setpoint • Evaporator entering and leaving fluid temperatures • Condenser water entering and leaving water temperature • Current limit .
37 CTV -PRC007-EN Controls Sequence of Operation For this sequence of operation it will be assumed that the control source has signaled the chiller to be in Automatic (i.e. when there is a load present, the chiller will turn on and when the load disappears, the chiller will turn off).
CTV -PRC007-EN 38 A demand for chilled water is determined by a temperature differential between the evaporator fluid setpoint and the supply fluid temperature. Start is inhibited and the condition enunciated if high condenser pressure or low oil temperature or high motor winding temperature is detected.
