Evaporator Variable Flow Compensation

This option includes transducers for the differential evaporator and condenser water pressures (psid). Flow switches or some other means to prove flow are still required and must be field connected.

The following data will be shown at the DynaView and TechView displays and at Tracer Summit.

How It Works

The Tracer chiller controller uses a patented, variable, water-flow compensation algorithm to maintain stable, precise capacity control. Variable flow compensation is a new optional control feature for CTV chillers.

It will automatically adjust capacity control to:

Maintain control stability at low flow.

Reject variable-flow disturbance.

If the water-pressure transducer fails and the flow switch continues to prove flow, water-flow compensation will be disabled and the design delta T will be used.

For applications designed to operate with variable-primary (VPF) water- flow, variable flow compensation allows the chiller to respond quickly to accelerating or decelerating water. By automatically adjusting the control gain, large changes in the water-flow rate can be tolerated.

For details, refer to CTV-PRC007-EN.

Condenser Limit

Condenser pressure is continuously monitored to provide a limit function that prevents High Pressure Cutout (HPC) trips. This protection is called Condenser Refrigerant Pressure Limit, or High Pressure Limit. A fully loaded compressor, operating at high Evaporator Leaving Water Temperature (ELWT) and high condenser temperatures causes high condenser pressures. The purpose of this limit is to avoid High Pressure Cutout (HPC) trips by allowing the Chiller to continue to run at a lower load instead of tripping off via HPC.

The Condenser Limit will be based from a pressure conversion from the Condenser Refrigerant Temperature sensor, unless there is a Condenser Refrigerant Pressure sensor installed (CDRP option). If the Condenser Refrigerant Pressure Sensor is installed, then the limit will be based from the Pressure sensor.

When limited by this action, “Condenser Pressure Limit” will be displayed as a sub-operating mode. The Condenser Limit Setpoint is factory set (93 percent of HPC), however can be altered via the service tool.
