TruVu™ ChillerVu™ Chilled Water System Optimizer
Technical Specifications
Features
System Benefits
Compatible with TruVu ChillerVu™ plant manager
Easy startup and commissioning using the i-Vu user interface
Fully plug-and-play compatible with the Carrier i-Vu building automation system, seamlessly integrating CWSO’s advanced setpoint reset into the ChillerVu plant control system
Supports integration to chiller plant equipment using BACnet and Modbus® protocols
Embedded trends and alarms provide insight into chiller plant performance, and also aid in system tuning, maintenance, and troubleshooting
Energy Savings
Chilled water setpoint algorithm adjusts the plant setpoint while monitoring and maintaining optimal chilled water system energy consumption
Dynamic condenser water setpoint algorithm adjusts to maintain optimal tower setpoint, minimizing chiller lift, compensating for ambient conditions and tower approach and providing optimum efficiency
Intelligent learning algorithms find the optimal energy usage while maintaining comfort conditions
Adapts “on the fly” to changing environmental and mechanical conditions as well as to changes in facility usage patterns
Software Features
Supports Metric and English units
Intuitive pre-built dashboard shows total plant energy usage and key operational parameters at a glance
Calculates and displays total system energy consumption kWh, peak demand in kW, tonnage, and overall system efficiency in kW/Ton
Version 3 of the CWSO control program (available for download) adds several key system features, including:
- Savings Assessment Mode – Once initial configuration and tuning is complete, the savings assessment mode allows the system to run one day on/one day off for a user defined period of time for baseline performance verification
- Additional I/O and default trending to provide greater insight into overall system operation and troubleshooting – highly beneficial for 3rd party plant system applications
- Enhanced system graphics
Robust Control Features
Easy, unobtrusive addition to virtually any communicating plant control system
Optimizes energy consumption across the entire chilled water system; supply and consumption
Supports system optimization of non-Carrier controlled plants via BACnet and Modbus protocols
