I would like to perform a parametric study of chilled water and supply air temperatures but unable to find them in my IDF. The idea is to put EMS sensors and actuators to change these two temperatures to find their relationship with energy consumption. I have used Chiller:Electric:EIR
as my chiller model, do I have to consider Condenser outlet temperature as the chilled water supply temperature? Also, How can I set supply air temperature to my own values? I have considered placing actuator as below;
EnergyManagementSystem:Sensor,
Occu_Schedule, !- Name
2864, !- Output:Variable or Output:Meter Index Key Name Occupancy Schedule
Schedule Value; !- Output:Variable or Output:Meter Name
EnergyManagementSystem:Actuator,
Chiller_set_point, ! Name
CHILLER CONDENSER OUTLET NODE, ! Component Name
System Node Setpoint, ! Component Type
Temperature Setpoint; ! Control Variable
EnergyManagementSystem:ProgramCallingManager,
Temp_69, !- Name
EndOfZoneTimestepBeforeZoneReporting, !- EnergyPlus Model Calling Point
Temp_Control69; !- Program Name 8
EnergyManagementSystem:Program,
Temp_Control69, !- Name
IF Occu_Schedule > 0,
SET Chiller_set_point = 6,
ELSE,
SET Chiller_set_point = 3,
ENDIF;
But when I plot Condenser outlet by using Output:Variable,*,Chiller Condenser Outlet Temperature,hourly; !- HVAC Average [C]
, it always give me different results then I assign. Any ideas?
