Package Content
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:

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.

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.

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.

In the above table blank entries 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 entries
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.
