Revision history [back]

I have a cooling tower and a fluid cooler in a EnergyPlus model. We are trying to control the operation based on outside temperature. If the Temperature is less than 40F the fluid cooler operates. If the temperature is greater than 40F the cooling tower operates. The following are the objects setup in the model:

CondenserEquipment List,
    FluidCooler Equipment List,
    FluidCooler:SingleSpeed,
    FluidCooler;

CondenserEquipmentList,
    CoolingTower Equipment List,
    CoolingTower:SingleSpeed,
    CoolingTower;

PlantEquipmentOperation:OutdoorDryBulb,
    Condenser_Loop Scheme 1,
    -32,4.5,FluidCooler Equipment List,
     4.5,50,CoolingTower Equipment List;

CondenserEquipmentOperationSchemes,
    Condenser_Loop Operation,
    PlantEquipmentOperation:OutDoorDryBulb,
    Condenser_Loop Scheme 1,
    On;

The condenser Loop operation is further referenced by the CondenserLoop Object.

However, Hourly outputs indicate both units operating at all times during the year. Is this setup not adequate for this type of control?
