Features and Benefits

•Communication capabilities: several communication levels are provided:

—local, through a PC workstation keyboard. Summit can be programmed to send messages to local or remote workstations and or a pager in the following cases:

—Analog parameter exceeding a programmed value.

—Maintenance warning.

—Component failure alarm.

—Critical alarm messages. In this latter case, the message is displayed until the operator acknowledges the receipt of the information. From the remote station it is also possible to access and modify the chiller plant’s control parameters.

•Remote communication through a modem: As an option, a modem can be connected to communicate the plant operation parameters through voice grade phone lines.

The remote terminal is a PC workstation equipped with a modem and software to display the remote plant parameters.

Chiller-Tower Optimization

Tracer Summit™ chiller-tower optimization extends Adaptive Control™ to the rest of the chiller plant. Chiller- tower optimization is a unique control algorithm for managing the chiller and cooling-tower subsystem. It considers the chiller load and real-time ambient conditions, then optimizes the tower setpoint temperature to maximize the efficiency of the subsystem.

Integrated Comfort™ System (ICS) The onboardTracer chiller controller is designed to be able to communicate with a wide range of building automation systems.To take full advantage of the capabilities of the chiller, incorporate your chiller into a Tracer Summit building automation system.

But the benefits do not stop at the chiller plant. AtTrane, we realize that all energy used in your cooling system is important. That is why we worked closely with other equipment manufacturers to predict the energy required by the entire system. We used this information to create patented control logic for optimizing the HVAC system efficiency.

The building owner’s challenge is to tie components and applications expertise into a single reliable system that provides maximum comfort, control and efficiency. Trane’s Integrated Comfort™ systems (ICS) are a concept that combines system components, controls and engineering applications expertise into a single, logical and efficient system. These advanced controls are fully commissioned and available on every piece ofTrane equipment, from the largest chiller to the smallest VAV box. As a manufacturer, onlyTrane offers this universe of equipment, controls and factory installation and verification.

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.
