blockSchedule

Information

Block that writes to a schedule object in EnergyPlus.

This model writes at every EnergyPlus zone time step the value of the input u to an EnergyPlus schedule with name name. For example, if EnergyPlus has 6 time steps per hour, as specified in the idf-file with the entry Timestep,6; and the input u to this block is

then EnergyPlus will receive the inputs

The parameter unit specifies the unit of the signal u. This unit is then converted internally to the units required by EnergyPlus before the value is sent to EnergyPlus. See Buildings.ThermalZones.EnergyPlus_24_2_0.Types.Units for the supported units. If the value of the parameter unit is left at its default value of Buildings.ThermalZones.EnergyPlus_24_2_0.Types.Units.unspecified, then the simulation will stop with an error.

Usage

To use an schedule, set up the schedule in the EnergyPlus idf file. For example, an entry may be

Schedule:Compact,
  INTERMITTENT,            !- Name
  Fraction,                !- Schedule Type Limits Name
  Through: 12/31,          !- Field 1
  For: WeekDays,           !- Field 2
  Until: 8:00,0.0,         !- Field 3
  Until: 18:00,1.00,       !- Field 5
  Until: 24:00,0.0,        !- Field 7
  For: AllOtherDays,       !- Field 9
  Until: 24:00,0.0;        !- Field 10

Next, instantiate the actuator in Modelica. For the above Schedule:Compact, the Modelica instantiation would be

  Buildings.ThermalZones.EnergyPlus_24_2_0.Schedule schInt(
    name = "INTERMITTENT",
    unit = Buildings.ThermalZones.EnergyPlus_24_2_0.Types.Units.Normalized)
    "Block that writes to the EnergyPlus schedule INTERMITTENT";

The entry units=Buildings.ThermalZones.EnergyPlus_24_2_0.Types.Units.Normalized will cause the value to be sent to EnergyPlus without any unit conversion.
