G36ReheatTerminalBoxCoolingAirflowSetpoint

Brief Description

Terminal box with reheat when the zone state is cooling following the guideline 36 recommendations

Index Description

  • Section 5.6.5.1 in ASHRAE Guideline 36-2021

Datapoints Description

  • mode_system: System operation mode

  • state_zone: Zone state (heating, cooling, or deadband)

  • flow_volumetric_air_cool_max: Maximum cooling airflow setpoint

  • flow_volumetric_air_setpoint_min: Minimum airflow setpoint during occupied mode

  • flow_volumetric_air_setpoint: Airflow setpoint

  • command_coil_heat: Heating coil command

  • temperature_air_discharge: Discharge air temperature

  • temperature_air_discharge_setpoint_min: Minimum discharge air temperature setpoint

Type Verification Description

Procedure-based

Assertions Type

Pass

Assertions Description

  • if temperature_air_discharge > temperature_air_discharge_setpoint_min and command_coil_heat > 0

  • fail

  • else

  • switch mode_system

  • case ‘occupied’

  • cooling_maximum = flow_volumetric_air_cool_max

  • minimum = v_min

  • case ‘cooldown’, ‘setup’

  • cooling_maximum = flow_volumetric_air_cool_max

  • minimum = 0

  • case ‘warmup’, ‘setback’, ‘unoccupied’

  • cooling_maximum = 0

  • minimum = 0

  • if minimum <= flow_volumetric_air_setpoint <= cooling_maximum

  • pass

  • else

  • fail

  • end
