Automated Centrifugal Chiller Diagnostician

Battelle Number: 14028-B | N/A

Technology Overview

Researchers and engineers at PNNL have developed an automated, sophisticated, multi-level, real-time centrifugal chiller diagnostician with diagnostics available under partial load conditions. This diagnostician provides auto-analysis of system efficiency and diagnoses the most probable causes of centrifugal chiller operations caused by common failures. It provides a generic diagnostic tool applicable to most major brands of centrifugal chiller units.

Advantages

  • automated, real-time diagnostics in visual display that identifies most probably causes of inefficiencies centrifugal chiller operations
  • applicable to most major brands of centrifugal chiller units
  • wide range of information can be monitored and displayed providing information about most common failures
  • unique features include:
  • applied a polynomial function generator to support partial load diagnostics rather than just full load diagnostics (industry standard)
  • event analysis and counter
  • event based data logging
  • innovative TCP/IP data acquisition for string type data
  • improved OPC communications
  • advanced intuitive GUI
  • diagnostic factory-engineered curve fit algorithms for a centrifugal chiller
  • ability to interpret string data (text messages) for faults vice just numerical data
