Models of rooms in test cell X3B

Information

This package contains models of rooms in test cell X3B of the FLEXLAB at LBNL. The following image is a drawing of test cell X3B. It shows how the different rooms in this example are connected, as well as providing the names used in this example for each of the rooms.

Room locations and names in X3AWithRadiantFloor

There are separate models for each room in test cell X3B. The model for the test cell itself is located in Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.TestCell, the model for the connected closet is located at Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.Closet, and the model for the connected electrical room is located at Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.Electrical. Each of the models were developed using construction and parameter information taken from architectural drawings. Accurate use of the models will likely require combining all three room models to each other.

The models in this package are intended to be connected to each other to develop a model of the entirety of test cell X3B. Several of the connections are to be made between walls connecting the two spaces to each other. Detailed information on the wall in each test cell can be found in the documentation for that test cell. The connections between each room in the test cell are described below.

Model of the closet connected to test cell X3A

Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.Closet

Information

This is a model for the closet attached to test cell 3B in the LBNL User Facility. This documentation describes the wall constructions used in the closet. Documentation describing how it should be connected to other models in the package to form a complete model of test cell X3B can be found in Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.

There are four different wall sections connected to the closet modeled here. They are shown in the figure below.

Wall sections in Closet model

The different wall sections are represented in the model according to the following table.

Wall Section Number	Description	Location in Model	Corresponding Layer
1	West wall connected to X3A.Closet	datConBou[2]	celDiv
2	North wall on the exterior of the buildings	datConExt[1]	higIns
3	East wall connected to Electrical	datConBou[1]	higIns
4	Air space connected to partition wall and door in TestCell model	Wall: datSurBou[1] Door: datSurBou[2]

There are two additional surfaces which are not included in the diagram. One is the model of the roof. It is modeled in datConExt[2] using the layer roo. The other is the floor, which is modeled in datConBou[3] using the layer slaCon.

Several of the connections in this model are intended to be connected to specific surfaces in other room models. The following table describes the connections to models outside of the X3B package. The connections in datConExt are not described in the table because they are connected to the external environment, and no additional heat port connections are necessary. A rationale for why the model is created this way is also provided if it is considered necessary.

surf_conBou[3]	Ground temperature		There is no specific connection which is appropriate connection for this construction. surf_conBou[3] represents the floor of the room, and must be connected to a heat port representing the ground temperature.

Model of the electrical room attached to test cell X3A

Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.Electrical

Information

This is a model for the electrical room connected to test cell 3B in the LBNL User Facility. Other models are provided for the main space of the test cell and the connected closet. This documentation describes the wall constructions used in the electrical room model. For documentation describing how the room models are to be connected to develop a model of the entire X3B test cell see Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.

There are 4 different wall sections described in the model. They are shown in the figure below.

Wall sections in TestCell model

The different wall sections are entered into the model according to the following table.

Wall Section Number	Description	Location in Model	Corresponding Layer
1	South air space connecting to TestCell	surBou[1]
2	West air space connecting to Closet	surBou[2]
3	North exterior wall	datConExt[1]	eleExt
4	East exterior door and wall	Wall: datConExt[2] Door: datConExt[3]	Wall: eleExt Door: extDooUn

There are two additional surfaces which are not included in the diagram. One is the model of the roof. It is modeled in datConExt[4] using the layer roo. The other is the floor, which is modeled in datConBou[1] using the layer slaCon.

Several of the connections in this model are intended to be connected to specific surfaces in other room models. The following table describes the connections to rooms which are not in the X3B package. The constructions in datConExt are not described in the table because they are connected to the external environment, and no additional heat port connections are necessary. A rationale for why the model is created this way is also provided if it is considered necessary.

Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.TestCell

Model of LBNL User Test Facility Cell X3A

Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.TestCell

Information

This is a model for test cell 3B in the LBNL User Facility. This model is intended to represent the main space in test cell 3B. This documentation describes the wall constructions used to model test cell X3B. Documentation describing how it is to be combined to other room models to create a model of the full test cell can be found in Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.

There are 6 different wall sections described in the model. They are shown in the figure below.

Wall sections in test cell model

The different wall sections are entered into the model according to the following table.

Wall Section Number	Description	Location in Model	Corresponding Layer
1	East exterior wall	datConExt[4]	EWal
2	South exterior wall with windows	datConExtWin[1]	R16p8Wal
3	West wall separating X3B and X3A	datConBou[1]	celDiv
4	North partition wall separating X3B and the closet	Wall: datConBou[2] Door: datConBou[3]	Wall: parCon Door: parDoo
5	North wall separating X3B and the electrical room	datConBou[4]	R52Wal
6	North exterior wall and door	Door: datConExt[1] Wall: datConExt[2]	Door: extDoo Wall: R16p8Wal

A seventh construction, not shown in the figure, models the ceiling. It is modeled in datConExt[3] using the layer R20Wal.

The test cell can be configured with several different floor types. The options include radiant conditioning, a slab on grade floor with no conditioning, or a raised floor. Because of this uncertainty in floor design, a model of the floor itself is not included in this model. The user must include a model for the floor in any applications of this model.

Several of the connections in this model are intended to be connected to specific surfaces in other room models. The following table describes the connections to models outside of the X3A package. The connections in datConExt are not described in the table because they are connected to the external environment, and no additional heat port connections are necessary.
