Buildings.Rooms.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor

Example model showing a use of X3A

Information

This model demonstrates one potential simulation using the models available in Buildings.Rooms.FLEXLAB.Rooms.X3A. This example simulates test cell X3A when it is conditioned with a radiant slab. This example model includes heat transfer between the test cell, the outdoor environment, the radiant slab conditioning the test cell, the connected electrical room and closet, and the neighboring test cells.

The connections between the test cell and the external models are described in the following table. Only models not included in the X3A package are included. For documentation describing the connections between X3A models see Buildings.Rooms.FLEXLAB.Rooms.X3A.

External model name	External model significance	External model port	X3A port
weaDat	Outdoor weather	weaDat.weaBus	X3A.weaBus
TNei	Neighboring test cells (X2B and X3B)	X2B: X3A.preTem2.port[1] X3B: X3A.preTem2.port[2]	X2B: X3A.surf_conBou[1] X3B: X3A.surf_conBou[2]

sla4A3	Radiant slab serving the south-central portion of X3A	sla4A3.surf_a	X3A.surf_surBou[3]
sla4A4	Radiant slab serving the south portion of X3A	sla4A4.surf_a	X3A.surf_surBou[4]
shaPos	Table describing the position of the window shade	shaPos.y[1]	X3A.uSha
intGai	Table specifying the internal gains in the space	intGai[1,2,3]	X3A.qGai_flow[1,2,3]
airIn	Prescribed airflow describing service air from the AHU	airIn.ports[1]	X3A.ports[1]
airOut	Outlet for ventilation air flow	airOut.ports[1]	X3A.ports[1]

The connections between the closet and external models are described in the following table. Only connections to models not included in the X3A package are described.

External model name	External model significance	External model port	clo port
intGaiClo	Table specifying the internal gains in the closet	intGaiClo[1,2,3]	clo.qGai_flow[1,2,3]
airInClo	Prescribed airflow describing service air from the AHU	airInClo.ports[1]	clo.ports[1]
airOutClo	Outlet for ventilation air flow	airOutClo.ports[1]	clo.ports[1]
preT	Prescribed temperature describing the ground temperature	preT.port	clo.surf_conBou[3]

The connections between the electrical room and external models are described in the following table. Only connections to models not included in the X3A package are described.

External model name	External model significance	External model port	ele port
intGaiEle	Table specifying the internal gains in the electrical room	intGaiEle[1,2,3]	ele.qGai_flow[1,2,3]
airInEle	Prescribed airflow describing service air from the AHU	airInEle.ports[1]	ele.ports[1]
airOutEle	Outlet for ventilation air flow	airOutEle.ports[1]	ele.ports[1]
preT	Prescribed temperature describing the ground temperature	preT.port	ele.surf_conBou[1]

The radiant slab is modeled using an instance of Buildings.Fluid.HeatExchangers.RadiantSlabs.SingleCircuitSlab. All of the inputs used to define the radiant slab are taken from the architectural drawings. The following table describes the connections between models used in the radiant slab. The connection to X3A is not included because it was previously described.

External model name	External model significance	External model port	Radiant slab port
watIn	Inlet for service fluid flow. Currently connects to a prescribed flow described in a table	watIn.ports[1]	sla.port_a
preT	Ground temperature beneath the radiant slab construction. Currently connects to a prescribed temperature defined in a table	preT.port	sla.surf_b
watOut	Outlet for service fluid flow	watOut.ports[1]	sla.port_b

The model only simulates the space conditions, the effects of the radiant slab, and the heat transfer between the rooms. The air handling unit, chilled water plant, shade control, internal gains, and ground temperature are all modeled by reading data from tables. Currently the ventilation air is read from an external data file, via the model airCon, while the others use tables described in the data reader model. The table below shows the name of data input files in the model, what physical phenomena the data file describes, the physical quantity of each data file output, and the source of the data.

Model name	Quantity described	Data source	y[1] significance	y[2] significance	y[3] significance	y[4] significance
shaPos	Position of the shade	Table in model	Position of the shade
intGai	Internal gains	Table in model	Radiant heat	Convective heat	Latent heat
airCon	Ventilation air from air handling unit	External text file	Mass flow rate			Temperature
watCon	Conditioning water from central plant	Table in model	Mass flow rate	Temperature
TGro	Ground temperature	Table in model	Temperature
intGaiClo	Internal gains for the closet	Table in model	Radiant heat	Convective heat	Latent heat
intGaiEle	Internal gains for the electrical room	Table in model	Radiant heat	Convective heat	Latent heat
airConEle	Ventilation air from AHU in the electrical room	External text file			Mass flow rate	Temperature
airConClo	Ventilation air from AHU in closet	External text file		Mass flow rate		Temperature
TNei	Temperature of the neighboring cells	Table in model	X2B	X3B

In the above table blank entires either show that there is no data to describe, or that the data is describing a quantity for a separate model. Two examples are:

The table for shaPos only contains data for shade position. Because it only has a y[1] value the remaining columns in the table are left blank.
airCon, airConClo, and airConEle all share an external data file. They all use the same temperature data, located in y[4] of the external data file. The three room models use different air mass flow rates. airCon uses the flow rate from y[1] in the data file, airConClo uses the flow rate from y[2], and airConEle uses the flow rate from y[3]. Thus, the other entires for each row in the table are left blank because the data is innapropriate for that particular model.

The ventilation air flow rates used during occupied hours in this example were calculated using the assumption of 4 air changes per hour (ACH). It is assumed that there is no ventilation flow during unoccupied hours.

Buildings.Rooms.FLEXLAB.Rooms.Examples.TestBedX3WithRadiantFloor

Example model of test cells X3A and X3B connected to form test bed X3

Information

This example models demonstrates how the Buildings.Rooms.FLEXLAB.Rooms.X3A and Buildings.Rooms.FLEXLAB.Rooms.X3B test cell models can be combined to form a simulation of test bed X3. The example is primarily a combination of Buildings.Rooms.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor and Buildings.Rooms.FLEXLAB.Rooms.Examples.X3BWithRadiantFloor. The example Buildings.Rooms.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor contains detailed documentation on these models. Some small changes were necessary to create the model of the test bed correctly. These changes are:

To make the connection between X3A and X3B possible two of the models from the X3A example were replaced with models designed for connection to X3B. Specifically, Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCell was replaced with Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCellNoCelDiv and Buildings.Rooms.FLEXLAB.Rooms.X3A.Closet was replaced with Buildings.Rooms.FLEXLAB.Rooms.X3A.ClosetNoCelDiv.
Connections between the two test cells do not exist in either of the other two examples. The connections between X3A and X3B were made following the documentation available in Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCellNoCelDiv and Buildings.Rooms.FLEXLAB.Rooms.X3A.ClosetNoCelDiv.
The data reader models in this example function in the same manner as in the other two examples, but their names had to be changed to avoid using the same name for multiple models in this example. Their names now contain a suffix describing the test cell they're connected to. For example, "airConA" is connected to test cell X3A and "shaPosB" is connected to test cell X3B.
TNei now only contains a temperature for test cell X2B. A temperature input for X3B is not needed because that test cell is now included in the model.

Buildings.Rooms.FLEXLAB.Rooms.Examples.X3BWithRadiantFloor

Example model showing a use of X3B

Information

This model demonstrates one potential simulation using the models available in Buildings.Rooms.FLEXLAB.Rooms.X3B. This model is nearly identical to Buildings.Rooms.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor. For a description of most of the connections and reasons behind them see that documentation. The changes to make this example model are:

The room models were changed from X3A models to X3B models.
Buildings.Rooms.FLEXLAB.Rooms.X3B.TestCell has one external wall (modeled in datConExt) which was a dividing wall (modeled in datConBou) in Buildings.Rooms.FLEXLAB.Rooms.X3A.TestCell. Because of this, a few construction indexes changed. Connections were made according to the table in Buildings.Rooms.FLEXLAB.Rooms.X3B.
