Evaporator screen
Figure 18: Evaporator screen
The evaporator 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.

Field name Description
Leaving Chilled Liquid
Temperature
The temperature of the liquid as it leaves the evaporator
Entering Chilled Liquid
Temperature
The temperature of the liquid as it enters the evaporator
Evaporator Small
Temperature Difference
The difference between the Leaving Chilled Liquid temperature and the Evaporator
Refrigerant temperature. The Evaporator Refrigerant temperature is represented by the
Refrigerant Temperature sensor input if the sensor is enabled. Otherwise it is represented by
the Evaporator Saturation temperature.
Evaporator Pressure The present refrigerant pressure in the evaporator
Leaving Chilled Liquid
Temperature Setpoints -
Setpoint
The present setpoint to which the chiller is operating, whether controlled locally or remotely
Leaving Chilled Liquid
Temperature Setpoints -
Shutdown
The Leaving Chilled Liquid Temperature at which the chiller shuts down on Leaving chilled
liquid - Low temperature cycling shutdown. It is calculated from the Leaving Chilled Liquid
Temperature Setpoint minus the Shutdown Offset setpoint and limited to chiller Minimum
Leaving Chilled Liquid Temperature.
