Block that outputs the operation mode

Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.OperationMode

Information

This block outputs VAV system operating mode. It is implemented according to ASHRAE guideline G36, section 5.4.3, section 5.4.4, section 5.4.5 and section 5.4.6.

Note that, from the user's point of view, schedules can be a set for individual zones, or they can be set for an entire zone group, depending on how the user interface is implemented. From the point of view of the BAS, individual zone schedules are superimposed to create a zone-group schedule, which then drives system behavior.

  1. All zones in each zone group shall be in the same zone-group operating mode. If one zone in a zone group is placed in any zone-group operating mode other than unoccupied mode (due to override, sequence logic, or scheduled occupancy), all zones in that group shall enter that mode.
  2. A zone group may be in only one mode at a given time.

Each zone group shall have the operating modes shown below.

Occupied Mode

A zone group is in the occupied mode when occupancy input uOcc is true. This input shall be retrieved from other sequences that specifies occupancy variation and time remaining to the next occupied period tNexOcc. A zone group could be in the occupied mode when any of the following is true:

Warm-up Mode

Warm-up mode shall start based on the zone with the longest calculated warm-up time maxWarUpTim requirement, but no earlier than 3 hours (preWarCooTim) before the start of the scheduled occupied period, and shall end at the scheduled occupied start time. Zones where the window switch indicates that a window is open shall be ignored. Note that for each zone, the optimal warm-up time shall be obtained from an Optimal Start sequences, computed in a separate block. The figure below shows the sequence.

Image of warm-up mode definition

Cooldown Mode

Cooldown mode shall start based on the zone with the longest calculated cooldown time maxCooDowTim requirement, but no earlier than 3 hours (preWarCooTim) before the start of the scheduled occupied period, and shall end at the scheduled occupied start time. Zones where the window switch indicates that a window is open shall be ignored. Note that for each zone, the optimal cooldown time shall be obtained from an Optimal Start sequences, computed in a separate block.

Image of cool-down mode definition

Setback Mode

During unoccupied mode, if any 5 zones (or all zones, if fewer than 5) in the zone group fall below their unoccupied heating setpoints, or if the average zone temperature of the zone group falls below the average unoccupied heating setpoint (uSetBac becomes true), the zone group shall enter setback mode until all spaces in the zone group are 1 °C (2 °F) above their unoccupied setpoints (uEndSetBac becomes true).

Image of setback mode definition

Freeze Protection Setback Mode

During unoccupied Mode, if any single zone falls below 4 °C (40 °F), the zone group shall enter setback mode until all zones are above 7 °C (45 °F), and a Level 3 alarm shall be set.

Setup Mode

During unoccupied mode, if any 5 zones (or all zones, if fewer than 5) in the zone group rise above their unoccupied cooling setpoints, or if the average zone temperature of the zone group rises above the average unoccupied cooling setpoint (uSetUp becomes true), the zone group shall enter setup mode until all spaces in the zone group are 1 °C (2 °F) below their unoccupied setpoints. Zones where the window switch indicates that a window is open shall be ignored.

Image of setup mode definition

Unoccupied Mode

Unoccupied mode shall be active if the zone group is not in any other mode.

Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.TrimAndRespond Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.TrimAndRespond

Block to inplement trim and respond logic

Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.TrimAndRespond

Information

This block implements the trim and respond logic according to ASHRAE guideline G36, PART 5.A.15 (trim and respond setpoint reset logic).

The trim and respond logic shall reset setpoint within the range minSet to maxSet. When the associated device is off (uDevSta=false), the setpoint shall be iniSet. The reset logic shall be active while the associated device is proven on (uDevSta=true), starting delTim after initial device start command. When active, every time step samplePeriod, trim the setpoint by triAmo. If there are more than numIgnReq requests, respond by changing the setpoint by resAmo*(numOfReq-numIgnReq), i.e., the number of requests minus the number of ignored requests, but no more than maxRes.

In other words, every time step samplePeriod:

Duplicate zone status output

Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.ZoneStatusDuplicator

Information

This block duplicates the signals of nZon by converting the input vector-valued signals of dimension nZon to a matrix-valued output of dimension [nGro, nZon].

This block prevent the use of for loops in the connectors between zones and zone groups by connecting all the zones to each Buildings.Controls.OBC.ASHRAE.G36_PR1.Generic.SetPoints.GroupStatus.

Parameters

TypeNameDefaultDescription
IntegernZon1Number of zones in input
