3 Our Case Study

3.1 University X

3.1 University X

We are going to install Building Operation as the building management system forUniversity X. The university is a campus of buildings for which heating and coolingare supplied from a Central Plant with an underground distribution system. The

case study focuses on the renovation of the Central Plant and the expansion of theSchool of Business.

Figure: The School of Business and the Central Plant

The Cooling Plant consists of a single chiller with a primary-secondary pumpingsystem. The secondary water loop serves four VAV air handling units with chilledwater coils located in the School of Business. The secondary loop has two waterpumps. Only one pump is required for 100 % of the load. The second pumpprovides 100 % backup. The secondary pumps are variable speed. The primarychilled water loop has a single constant volume chilled water pump. The condenserloop rejects heat by means of a cooling tower. The condenser loop has a single

constant volume condenser water pump. The tower has two constant speed, draw-through fans to increase the capacity of the tower above the natural draft capacity.A diverting valve can be used to protect the chiller from condenser water thermalshock. The water leaving the condenser can be diverted back to the inlet of thecondenser without any cooling effect.



28/212

3 Our Case Study

3.1 University X

Figure: Cooling Plant diagram

The heating plant consists of two boilers in parallel, each with their own inlinepumps. Much of the time only one boiler is required to meet the load but undergreater load, both boilers will operate at the same time. The flow from the twoboilers comes together in a common supply header. There is a line from the supplyheader to the mechanical systems that require a source of hot water. This line hastwo constant volume distribution pumps in parallel. Only one is required to meetthe load. The second is back-up and lead-lag is used to alternate which pumpruns. The water returning from the mechanical systems flows into the return headerwhere it can be pumped by the inline pumps through the boilers. There is acommon line between the supply header and the return header. When the inlinepumps are flowing at a rate that exceeds the distribution pump flow rate, the waterflow in the common line is from the supply header to the return header. When thedistribution pump is flowing at a rate that exceeds the combined inline pump flowrates, flow in the common line is from the return header to the supply header. Eachboiler has its own self contained control system that interfaces with BuildingOperation through a combination of binary electrical control and network variables.The inline pumps are locally controlled by the self contained control system.

6 Creating I/O Points and Variables in the b3 BACnet Devices

Our Example

In this chapter, you create all the b3 BACnet input points, output points, and valuesthat will reside within the Air Handling Unit controller and also the Variable AirVolume controller. The data from these points and values will be mirrored up tovalues that reside within the Automation Server. The Automation Server will analyzethis data and perform logical decisions before passing the data back to the b3BACnet devices that are controlling the system.

7 Creating Variables in the Automation Server

Our Example

In this chapter, you create all the server values and BACnet values that reside in theAutomation Server within the BACnet Interface. The server values are mirrored fromthe values in the b3 BACnet devices. Programs in the Automation Server performlogical decisions to these values and then pass that data down to the BACnetvalues that reside in the Automation Server within the BACnet Interface. Thosevalues are then passed down to the b3 BACnet devices.



98/212


7.1 Creating a Server Analog Value


You create analog values in the Automation Server or Enterprise Server for thefollowing reasons:

A variable needs to be bound to multiple programs.

A calibrated analog input variable needs to be forced.

For more information, see theBindings Overviewtopic on WebHelp.

In this example, you create an analog value named VlvPosn_AS in the AutomationServer AHU_01 folder.

To create a server analog value

1.1. In WorkStation, in the System Tree pane, select the server or folder whereyou want to add an analog value. In this example, select ...University XES1/Servers/CPlant AS/AHU_01/Values.


3.3. In the object type list, selectAnalog Value.

4.4. In the Name box, type a name for the analog value. In this example, type

7.4 Creating a BACnet Value


You create a BACnet analog, digital, or multistate value in a local server so you canthen configure a control system parameter for the server. The server can be anAutomation Server or an Enterprise Server. The BACnet values that you create are

visible to other workstations and devices in the BACnet internetwork. You createBACnet values for a server in the Application folder of the server's BACnet Interface.

For more information, see theBACnet Objects and Propertiestopic on WebHelp.

In this example, you create a BACnet analog value named AHU_01_DatSP in theApplication folder of the Automation Server's BACnet Interface.

To create a BACnet value

1.1. In WorkStation, in the System Tree, expand the BACnet Interface and thenselect Application. In this example, expand ...University XES1/Servers/CPlant AS/BACnet Interface and then select

Application.


3.3. In the object type list, select the type of BACnet value that you want to create.Do not select String Value or Time Stamp Value, which are not BACnetobject types. In this example, select BACnet Analog Value.

4.4. In the Name box, type a name for the value. In this example, typeAHU_01_DatSP.
