Evaporator screen
Figure 12: Evaporator screen
This screen displays a cutaway view of the chiller evaporator. All setpoints relating to the
evaporator side of the chiller are maintained on this screen. Animation of the evaporation process
indicates whether the chiller is presently in a RUN condition. Animation of the liquid flow indicates
chilled liquid flow.
Table 13: Display only fields
Field/LED name Description
Leaving Chilled Liquid
Temperature
Displays the temperature of the liquid as it leaves the evaporator.
Entering Chilled Liquid
Temperature
Displays the temperature of the liquid as it enters the evaporator.
Evaporator Small
Temperature
Difference
Displays the difference between the Leaving Chilled Liquid temperature
and the Evaporator Refrigerant temperature. The Evaporator Refrigerant
temperature will be represented by the Refrigerant Temperature sensor
input if the sensor is enabled, otherwise it will be represented by the
Evaporator Saturation temperature.
Evaporator Pressure Displays the present refrigerant pressure in the evaporator.
Leaving Chilled Liquid
Temperature Setpoints
– Setpoint
Displays the present setpoint to which the chiller is operating, whether
controlled locally or remotely.
Leaving Chilled Liquid
Temperature Setpoints
- Shutdown
Displays the Leaving Chilled Liquid Temperature at which the chiller will
shutdown on LEAVING CHILLED LIQUID – LOW TEMPERATURE cycling
shutdown. It is calculated automatically from the temperature setpoint
minus the shutdown offset setpoint and limited to chiller minimum.
