  1. +The controller currently assumes the boilers are constantly available. Future +modifications will include logic for detecting availability. +
    2. +
  2. +The controller currently does not accommodate lead-lag rotation of boilers and +pumps. Future modifications will include existing sequences for lead-lag rotation. +
    3. +
  3. +The controller currently supports only a singular primary loop. Future modifications +will enable the support of hybrid plants with multiple primary loops, with individual +loops consisting of either condensing or non-condensing boilers. +

+Block that controls boiler status and isolation valve position, initiates status +change in devices like pumps and minimum flow bypass valve, and resets plant +parameters like minimum flow setpoint when there is a stage-down command. +This development is based on ASHRAE Guideline 36, 2021, sections 5.21.3.11 - 5.21.3.18, +which specify the step-by-step control of devices during boiler staging down process. +

+
    +
  1. +Identify the boiler(s) that should be disabled (and enabled). This is implemented in block nexBoi. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.Staging.Processes.Subsequences.NextBoiler +for more decriptions. +
    2. +
  2. +If the stage change process involves disabling a larger boiler and enabling a smaller boiler, + +
    3. +
  3. +If the stage down process does not involve turning on a smaller boiler, start the +staging down process immediately by changing yBoi using disBoi. +
    4. +
  4. +Wait for time delBoiEna before closing the isolation valve for the +disabled boiler using disHotWatIsoVal1 and initiating the pump stage +change process. +
    5. +
  5. +End the staging process after the valve has been closed and the pump change process +completion signal has been received. Send rising edge signal through yStaChaPro +to indicate the same. +

+Block that controls boiler status and isolation valve position, initiates status +change in devices like pumps and minimum flow bypass valve, and resets plant +parameters like hot water supply temperature setpoint and minimum flow setpoint +when there is a stage-up command. +This development is based on ASHRAE Guideline 36, 2021, sections 5.21.3.11 - 5.21.3.18, +which specify the step-by-step control of devices during boiler staging up process. +

+
    +
  1. +Identify the boiler(s) that should be enabled (and disabled). This is implemented in block nexBoi. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.Staging.Processes.Subsequences.NextBoiler +for more decriptions. +
    2. +
  2. +Initiate the process to reset the minimum hot water flow setpoint for the minimum +flow bypass valve, + +The minimum flow setpoint is reset in sequence +( +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.MinimumFlowBypass.Subsequences.FlowSetpoint). +Block minBypRes checks if the new setpoint is achieved +( +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.Staging.Processes.Subsequences.ResetMinBypass). +
    3. +
  3. +Start the next hot water pump and/or open the hot water isolation valves using the +block enaHotWatIsoVal using sequence implemented in +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.Staging.Processes.Subsequences.HWIsoVal +for the valves and initiating the pump change process with the pulse signal yPumChaPro. +Once the pumps have been reset, the controller receives a pulse signal on the +input uPumChaPro. +
    4. +
  4. +After waiting for time delPreBoiEna, the boiler status yBoi +is changed using the boiler status controller enaBoi implemented in the sequence + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.Staging.Processes.Subsequences.EnableBoiler. +
    5. +
  5. +If the stage up process does not involve turning off a smaller boiler, end the +staging up process by sending a pulse signal through yStaChaPro. Otherwise, + +

+ This subsequence is not directly specified in ASHRAE Guideline 36 as it + provides a side calculation pertaining to generalization of the staging + sequences for any number of boilers and stages provided by the user. +

+

This subsequence is used to generate the boiler stage setpoint + ySta and a boolean vector of + boiler status setpoint indices y + for the ySta stage.

+

The inputs to the subsequece are:

+ +

+ If stage down and stage up happen at the same time for any faulty reason the + staging down is performed. +

+

+ If stage down or stage up signal is held for a time longer than delStaCha + multiple consecutive stage change signals are issued. +

+

+ At plant enable the intial stage is held for at least delStaCha + and until any stage up or down signal is generated. +

+

+ Per ASHRAE Gudeline 36, 2021,section 5.21.3.9, item a, each stage shall have + a minimum runtime of delStaCha. +

+This controller block rotates equipment, such as chillers, pumps or valves, in order +to ensure equal wear and tear. It is intended to be used for lead/lag and +lead/standby operation of two devices or groups of devices. The implementation is +based on the specification from ASHRAE Guideline36-2021, section 5.1.15.1.-4. +

+

+The controller takes as inputs the current device proven ON/OFF status vector uDevSta, +lead device status setpoint uLeaStaSet and lag device status setpoint uLagStaSet. +The controller features the following rotation subsequences to generate the device status setpoints yDevStaSet +and device roles yDevRol outputs: +

+ +

+The +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Generic.EquipmentRotation.Subsequences.Two subsequence allocates +the status setpoints yDevStaSet to devices based on the rotation signal. +

+

+The output vector yDevRol indicates the role of each device, where true +represents a lead role and false represents a lag or a standby role. +

+

+The indices of both output vectors and the uDevSta input vector represent physical devices. +

+

+In addition to the specification in Guideline36, this model allows the user to: +

+

+The user may chose to start counting time from simulation start to generate the +rotation signal at regular intervals rotationPeriod by setting a +flag sinTimSta to true, or to use a calendar. +

+

+If a calender is used the user needs to select the time of the day as an hour between 0 and 23 at which the rotation shall occur. +Hour 0 is midnight. +The block implements two options to select the time interval for the equipment rotation: +

+ +

+To enable weekly intervals set the weeInt to true, otherwise a number of days can be used. +

+Block that outputs chilled water minimum flow setpoint for primary-only +plants with a minimum flow bypass valve, +according to ASHRAE Guideline36-2021, +section 5.20.8 Chilled water minimum flow bypass valve. +

+

+1. For plants with parallel chillers, bypass valve shall modulate to maintain minimum +flow as measured by the chilled water flow meter at a setpoint that ensures minimum +flow through all operating chillers, as follows: +

+ + + + + + + + + + + + + + + + + + + + + + +
Chiller Minimum flow Maximum flow
1minFloSet[1]maxFloSet[1]
2minFloSet[2]maxFloSet[2]
.........
+
+ +

+2. For plants with series chillers, bypass valve shall modulate to maintain minimum +flow as measured by the chilled water flow meter at a setpoint equal to the largest +minFloSet of the operating chillers in current stage. +

+

+3. If there is any stage change requiring a chiller on and another chiller off, +the minimum flow setpoint shall temporarily change to account for the +minFloSet of both the chiller to be enabled and to be disabled +prior to starting the newly enabled chiller. +

+

+Note that when there is a stage change requiring a change in the +minimum flow setpoint, the change should be slowly. +For example, this could be accomplished by resetting the setpoint X GPM/second, +where X = (NewSetpoint - OldSetpoint) / byPasSetTim. +

+Block that controls devices when there is a stage-down command. This sequence is for +water-cooled primary-only parallel chiller plants with headered chilled water pumps +and headered condenser water pumps, or air-cooled primary-only parallel chiller +plants with headered chilled water pumps. +This development is based on ASHRAE Guideline 36-2021, +section 5.20.4.17, which specifies the step-by-step control of +devices during chiller staging down process. +

+
    +
  1. +Identify the chiller(s) that should be enabled (and disabled, if have_ponyChiller=true). +This is implemented in block nexChi. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.NextChiller +for more decriptions. +
    2. +
  2. +Start the staging down process, + +These are implemented in block dowSta. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.DownStart +for more decriptions. +
    3. +
  3. +When the controller of the chiller being shut off indicates no request for chilled +water flow (uChiWatReq=false), slowly (chaChiWatIsoTim) +close the chiller's chilled water isolation valve to avoid a sudden change in flow +through other operating chillers. +This is implemented in block disChiIsoVal.

+Block updates chiller chilled water isolation valve enabling-disabling status when +there is stage change command (uStaPro=true). It will also generate +status to indicate if the valve reset process has finished. +This development is based on ASHRAE Guideline 36-2021, +section 5.20.4.16, item e and section 5.20.4.17, item c, which specifies when +and how the isolation valve should be controlled when it is in stage changing process. +

+ +

+The valve should open or close slowly. For example, this could be accomplished by +resetting the valve position X /seconds, where X = (endValPos - +iniValPos) / chaChiWatIsoTim. +The valve time chaChiWatIsoTim should be determined in the field. +

+

+This sequence will generate array yChiWatIsoVal which indicates +chilled water isolation valve position setpoint. yEnaChiWatIsoVal +will be true when all the enabled valves are fully open and all the disabled valves +are fully closed. +

+Block that controls devices at the first step of chiller staging down process. +This development is based on ASHRAE Guideline 36-2021, +section 5.20.4.17, item a and b. The sections specifies the first step of +staging down process. +

+

+For the stage-down process that requires a smaller chiller being enabled and a +larger chiller being disabled (uOnOff=true): +

+
    +
  1. +Command operating chilers to reduce demand to 75% (chiDemRedFac) of +their current load or a percentage equal to current stage minimum cycling operative +partial load ratio (yOpeParLoaRatMin), whichever is greater. Wait until acutal +demand < 80% of current load up to a maximum of 5 minutes (holChiDemTim) +before proceeding. This is implemented in block chiDemRed. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.ReduceDemand +for more decriptions. +
    2. +
  2. +Slowly change the minimum chilled water flow setpoint to that approriate for the +stage transition (minChiWatSet). After new setpoint is achieved, wait +1 minutes (aftByPasSetTim) to allow loop to stabilize (minBypRes). +See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.MinimumFlowBypass.FlowSetpoint +and + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.ResetMinBypass +for more decriptions. +
    3. +
  3. +Enable head pressure control for the chiller being enabled. Wait 30 seconds (waiTim). +It is implemented in block enaHeaCon, see + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.HeadControl +for more decriptions. +
    4. +
  4. +Slowly open chilled water isolation valve of the smaller chiller being enabled. +Determine valve timing chaChiWatIsoTim in the field as that required +to prevent nuisance trips. +It is implemented in block enaChiIsoVal, see + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.CHWIsoVal +for more decriptions. +
    5. +
  5. +Start the smaller chiller after its chilled water isolation valve is fully open. +Wait 5 minutes (proOnTim) after the newly enabled chiller to prove that +it is operating correctly, then shut off the larger chiller and release the demand +limit (yReaDemLim=true). +It is implemented in block disChi, see + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.DisableChiller +for more decriptions. +
    6. +
+

+For staging down from any other stage (uOnOff=false), just shut off +the last stage chiller. This is implemented in block disChi, see + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.DisableChiller +for more decriptions. +

+Block that controls devices at the ending step of chiller staging up process. +This development is based on ASHRAE Guideline 36-2021, +section 5.20.4.16, item f and g. These sections specify the controls of +devices at the ending step of staging up process. +

+

+For the stage-up process that does not require a smaller chiller being disabled +and a larger chiller being enabled (uOnOff=false), +

+ +

+For any stage change during which a smaller chiller is diabled and a larger chiller +is enabled (uOnOff=true), after starting the next stage chiller +specified above, do following: +

+
    +
  1. +Wait 5 minutes (proOnTim) for the newly enabled chiller to prove that +is operating correctly, then shut off the small chiller (nexDisChi). +This is implemented in block enaChi. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.EnableChiller +for more decriptions. +
    2. +
  2. +When the controller of the smaller chiller being shut off indicates no request +for chilled water flow (uChiWatReq=false), slowly close the chiller's +chilled water isolation valve to avoid a sudden change in flow through other +operating chillers. +This is implemented in block disChiIsoVal. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.CHWIsoVal +for more decriptions. +
    3. +
  3. +When the controller of the smaller chiller being shut off indicates no request for +condenser water flow (uConWatReq=false), disable the chiller's head +pressure control loop. +This is implemented in block disHeaCon. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.HeadControl +for more decriptions. +
    4. +
  4. +Change the minimum flow bypass setpoint to that appropriate for the new stage. +This is implemented in block minChiWatSet. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.MinimumFlowBypass.FlowSetpoint +for more decriptions. +
    5. +
  5. +Block minBypSet will then check if the new chilled water flow setpoint +has been achieved. See + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Staging.Processes.Subsequences.ResetMinBypass +for more decriptions. +

+The instance chiOnOff shows how to enable and disable chillers when +the staging down process requires one chiller being enabled and another chiller +being disabled. The instance chiOff shows how the chiller being +disable when the staging down process does not require other chiller being enabled. +

+

+For the instance chiOnOff, initially the plant has chiller 1 and 2 +operating. When staging down, it requires chiller 3 being enabled and chiller 2 +being disabled. +

+It has four instances as below to demonstrate the process of identifying next +changing chiller(s) when the plant is in staging process. +

+

+The instance nexChi shows how the changing chillers being identified +in a staging up process that requires a large chiller being enabled and a small +chiller being disabled. The plant stages up from stage 1 that requires chiller 1 +operating to stage 2 that requires chiller 2 operating. +

+ + +

+The instance nexChi1 shows how the changing chillers being identified +in a staging up process that requires one additional chiller being enabled. The +plant stages up from stage 1 that requires chiller 1 operating to stage 2 that +requires both chiller 1 and chiller 2 operating. +

+ + +

+The instance nexChi2 shows how the changing chillers being identified +in a staging down process that requires a large chiller being disabled and a small +chiller being enabled. The plant stages down from stage 2 that requires chiller 2 +operating to stage 1 that requires chiller 1 operating. +

+ + +

+The instance nexChi3 shows how the changing chillers being identified +in a staging down process that requires one additional chiller being disabled. The +plant stages down from stage 2 that requires both chiller 1 and chiller 2 operating +to stage 1 that requires just chiller 1 operating. +

+Block that outputs cooling tower fan speed ySpeSet when both waterside +economizer and chillers are enabled, i.e. integrated operation. This is implemented +according to ASHRAE Guideline36-2021, section 5.20.12.2, item c.1. +

+

+When the waterside economizer is enabled (uWse=true) and chillers +are running (uChi=true): +

+
    +
  1. +Fan speed shall be equal to waterside economizer tower maximum speed. +
    2. +
  2. +The waterside economizer tower maximum speed shall be reset by a direct acting PID +loop maintaining the chiller load at 110% of the sum of minimum cycling load for +the operating chillers. Map the tower maximum speed from minimum speed +fanSpeMin at 0% loop output to 100% speed at 100% loop output. +Bias the loop to launch from 100% output. +
    3. +
  3. +When starting integrated operation after previously operating with only the waterside +economizer, hold the tower maximum speed at 100% for 10 minutes (intModTim) +to give the chiller time to get up to speed and produce at least minimum cycling +load, then enable the loop. +

+This package contains validation models for the classes in + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Towers. +

+

+ This class implements a boiler plant primary loop with 2 condensing boilers, + 2 variable-speed primary pumps, and a common decoupler leg. + Additionally, it includes PID loops to operate the boilers at the required + supply temperature setpoint signal. +

+ +

+ The intended use-case for this class is to combine it with single or multiple + instances of the secondary loop class + + Buildings.Examples.BoilerPlants.Baseclasses.SimplifiedSecondaryLoad + + to create a primary-secondary boiler plant with variable-primary and variable-secondary + pumps. +

+This model couples the boiler plant model for a primary-secondary, condensing boiler +plant with variable speed primary and secondary pumps with controllers for the +primary loop and the secondary loops. +

+

+The primary loop is modeled by the + +Buildings.Examples.BoilerPlants.Baseclasses.BoilerPlantPrimary + +instance boiPlaPri and is coupled with the secondary loop instances +secLoo1 and secLoo2 of class + +Buildings.Examples.BoilerPlants.Baseclasses.SimplifiedSecondaryLoad +. +The primary loop is controlled by the + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.PrimaryController + +instance conBoiPlaPri, and the secondary loops secLoo1 and +secLoo2 are controlled by the secondary loop controller + +Buildings.Controls.OBC.ASHRAE.G36.Plants.Boilers.Pumps.SecondaryPumps.Controller + +instances secPumCon1 and secPumCon2, respectively. +

+ +

+The reference loads for activating the system are calculated by simulating the DOE +prototype large office building EnergyPlus model (ASHRAE 90.1-2019 version), and then summing +up the simulated flowrates through each of the heating coils in the building. The +return temperature to the hot water plant is also noted. The values are then used +to apply loads on this model by simulating equivalent loads on the secondary loops. +

+ +

A few salient points about the default system sizing values.

+ + +

The validation plots are as follows.

+
    +
  1. +Plot-1 represents the operation of the secondary loop-1 secLoo1. The plot +shows how the load model within the secondary loop applies a load fraction proportional +to the input return temperature and mass flow rate when the plant is enabled. The +plot also shows the secondary pump speed control to achieve the required differential +pressure setpoint. +
    2. +
  2. +Plot-2 is similar to plot-1, and demonstrates the same operations for the secondary +loop-2, secLoo2. +
    3. +
  3. +Plot-3 represents the primary loop operation, consisting of plant enable, +temperature setpoint reset, and the subsequent staging operations +to meet that load. It shows the enable and disable of the two boilers, and the +opening and closing of their respective isolation valves based on the staging setpoint. +The user can observe that the plant operates at the highest stage setpoint when the +maximum flowrate is drawn by the secondary loops. +
    4. +
  4. +Plot-4 represents the hydronic operations in the primary loop, including the staging +of the primary pumps such that the number of enabled pumps is equal to the number +of enabled boilers. The primary pump speed regulates the flow measured in the +decoupler leg to zero flowrate. +
