Buildings.Fluid.DXSystems.Heating.BaseClasses.Types.DefrostOperation
Enumeration defining two methods for defrost
Information
Enumeration for the method of defrost. The possible values are:
Enumeration | Description |
---|---|
reverseCycle |
Cycle the refrigerant in flow in reverse to defrost the outdoor coil. |
resistive |
Use a resistive heating element on the outdoor coil for defrost. |
Modelica definition
type DefrostOperation = enumeration(
reverseCycle
"Cycle DX coil in reverse flow to defrost outdoor coil",
resistive
"Use resistive element on outdoor coil to defrost")
"Enumeration defining two methods for defrost";
Buildings.Fluid.DXSystems.Heating.BaseClasses.Types.DefrostTimeMethods
Enumeration defining two methods for defrost time fraction calculation.
Information
Enumeration for the calculation methods for defrost time fraction. The possible values are:
Enumeration | Description |
---|---|
timed |
Run the defrost operation for a fixed time duration fraction of the timestep. |
onDemand |
Run the defrost operation for on a time duration fraction for the timestep, that is calculated from the outdoor air temperature and humidity ratio. |
