Mechanical Specifications

Condenser

The condenser is designed, tested and stamped in accordance with the ASME Boiler and Pressure Vessel Code or PED (European Code) for a refrigerant side working pressure of 15.2 bars (220 psig). It consists of a carbon steel shell with steel tube sheets welded to each end. Individually- replaceable, externally-fi nned and internally-grooved 19 mm(¾ in.) and 25.4 mm (1.0 in.) nominal diameter seamless copper tubes are mechanically expanded into the tubesheets.

Two-pass water boxes are bolted to the tube sheets. Grooved pipe connections are standard.

flanged connections are optionally available. Maximum waterside working pressureof 10.5 bars (150 psi) is standard. The waterside is hydrostatically tested at ASME 1.5 times, PED 1.43 times, GB 1.25 times maximum working pressure.

Unit Control Panel

The microcomputer control panel is factory installed and tested on the CVGF unit. All controls necessary for the safe and reliable operation of the chiller are provided including oil management, interface to the starter, and three phase motor overload protection. It also includes comprehensive status and diagnostic monitoring controls. A control power transformer included in the starter panel powers the control system.

The microprocessor controller is compatible with reduced voltage or full voltage electro-mechanical starters, and solid state starter. Starter for Europe with the CE mark is available.

The microcomputer control system processes the leaving evaporator fluid temperature sensor signal to satisfy the system requirements across the entire load range.

The controller will load and unload the chiller via control of the stepper- motor/actuator which drives the inlet guide vanes open and closed. The load range can be limited either by a control limitor or by an inlet guide vane limit (whichever controls the lower limit). It will also control the evaporator and condenser pumps to insure proper chiller operation.

Status and 10 active diagnostics are communicated to the operator via display with a tabbed navigation system. Setpoints are entered through the touch-sensitive screen. Countdown timer displays remaining time(s) during wait states and time out periods. Non-volatile memory saves unit set-up information during power loss without the need for batteries. Password protection is provided to secure the operator interface. PC-based service tool software displays the last 60 active or 60 historic diagnostics, indicating the time, date of occurrence, and system parameters at the time of the diagnostic.

The service tool provides advanced troubleshooting and access to sophisticated configuration settings not needed during operation of the chiller. Any PC that meets the installation requirements may be loaded with the service tool software via download from www.trane.com.

Unit mounted display is capable of displaying chiller parameters in IP or SI units, and language in English and any 2 downloadable and/or locally translated languages.

CVGF specifications

The Trane CVGF series is a revolutionary innovation in the world of commercial HVAC systems, designed to deliver unparalleled performance and energy efficiency. This air-cooled chiller line is specifically engineered to meet the demands of modern buildings, making it an ideal choice for various applications such as offices, hospitals, and educational institutions.

One of the standout features of the CVGF series is its use of the Trane Adaptive Control technology. This advancement provides the system with real-time data analytics, allowing it to automatically adjust cooling output based on environmental conditions and load requirements. This level of adaptability not only enhances occupant comfort but also contributes to significant energy savings, aligning with sustainability goals.

The CVGF chillers also incorporate a robust and efficient scroll compressor, which operates quietly and minimizes vibration. This design choice ensures reliability and longevity while reducing operational noise levels, making it suitable for installations in noise-sensitive environments. Furthermore, the scroll compressor's efficiency plays a crucial role in achieving a higher coefficient of performance (COP), which translates to lower energy costs.

In terms of environmental responsibility, the CVGF series is designed with an eco-friendly refrigerant that supports lower global warming potential (GWP). Committed to sustainability, Trane ensures that these chillers not only meet but exceed regulatory requirements, allowing businesses to operate with a reduced carbon footprint.

Another remarkable characteristic of the CVGF line is its modular design, which simplifies installation and maintenance. The units are compact and can be easily integrated into existing infrastructure, minimizing disruption during upgrades or replacements. The straightforward maintenance protocols further enhance the system’s uptime, ensuring users enjoy consistent and reliable cooling performance.

Moreover, the CVGF chillers are equipped with advanced monitoring capabilities, accessible through Trane’s proprietary software. This feature enables facility managers to oversee system performance from any location, facilitating proactive adjustments and timely maintenance interventions.

Overall, the Trane CVGF series stands out as a cutting-edge solution for effective and sustainable cooling in commercial applications. By combining innovative technologies, energy-efficient design, and user-friendly features, the CVGF offers a comprehensive approach to achieving optimal climate control while meeting the challenges of the future.
