Tracer AdaptiViewTM Controller

Today's centrifugal chillers offer predictive controls that anticipate and compensate for load changes. Other control strategies made possible with the Tracer AdaptiViewTM controls are:

Feedforward Adaptive Control

Feedforward is an open-loop, predictive control strategy designed to anticipate and compensate for load changes. It uses evaporator entering-water temperature as an indication of load change. This allows the controller to respond faster and maintain stable leaving-water temperatures.

Soft Loading

The chiller controller uses soft loading except during manual operation. Large adjustments due to load or setpoint changes are made gradually, preventing the compressor from cycling unnecessarily. It does this by internally fi ltering the setpoints to avoid reaching the differential-to- stop or the current limit. Soft loading applies to the leaving chilled-water temperature and current- limit setpoints.

Multi-Objective Limit Arbitration

There are many objectives that the controller must meet, but it cannot satisfy more than one objective at a time. Typically, the controller’s primary objective is to maintain the evaporator leaving- water temperature.

Whenever the controller senses that it can no longer meet its primary objective without triggering a protective shutdown, it focuses on the most critical secondary objective. When the secondary objective is no longer critical, the controller reverts to its primary objective.

Fast Restart

The controller allows the CenTravac chiller to restart during the postlube process. If the chiller shuts down on a nonlatching diagnostic, the diagnostic has 30–60 seconds to clear itself and initiate a fast restart. This includes momentary power losses.

Building Automation and Chiller Plant Control

Trane Tracer SummitTM building automation systems include pre-engineered and fl exible control for chiller plants. It can control the operation of the complete installation: chillers, pumps, cooling towers, isolating valves, air handlers and terminal units.Trane can undertake full responsibility for an optimized automation and energy management

for the entire chiller plant.

The main functions are:

•Chiller sequencing: equalizes the number of running hours of the chillers. Different control strategies are available depending on the confi guration of the installation.

•Control of the auxiliaries: includes input/output modules to control the operation of the various auxiliary equipments (water pumps, valves, cooling towers, etc.)
