### 2.5.2. Identification of compartments

¨ To identify, that means specify the features of partitions it is necessary to carry out following operations:

1. Start the Instal-heat&energy program from Package Manager. After running the program you can see the man menu and toolbar. From main menu “File” select the command “Open” or click the button „Open” located on the toolbar. Then find the project file saved previously in Instal-therm, select it and open. The project will be loaded into program and opened in “General data”. Method of completion of general data will be described in chapter 2.3.

2. Select from the project data list the position „Building structure” and using the icon in lower part of screen open the view of building structure, so that all compartments of building could be visible. After clicking on chosen compartment on the right side of screen a window for compartment data edition will appear – „Building structure: Compartment”. The project loaded from Instal-therm has in the table completed data concerning partition type, orientation towards cardinal points of the compass and adjacent partitions, dimensions and their assigning to the selected ones as sub-partitions. It can also contain completed values of temperatures outside and inside of compartments.

Columns: “Uo” with the value of heat transfer coefficient with value of corrected heat coefficient “Uc” for each partition and “Name” are not completed on this stage, also the partitions are not assigned to compartments.

3. To complete the value of „Uo” and “Uc” coefficient it is necessary to define the partitions. Defining of partitions has been described in chapter 2.4.

4. Defined partitions are to be assigned to compartments. Assigning can be performed in tabular editor of Instal-heat&energy or in graphical editor of Instal-therm.

To assign partitions to compartments, in edition window „Building structure: Compartment”, in data table of compartment, in column „Name” of specified partition, using the button declare the usage in specified place a previously defined partition. It is important to assign properly the partition to its type and location. Because tabular assigning of partitions requires attention of the User, it is recommended to make simultaneously use of storeys plan views of the building to avoid mistakes. For this reason in case of complex projects in order to provide quicker and more secure work the identification of partitions should be performed in graphical editor of Instal-therm program. To do this, after defining of all partitions, save the file a disc and go to Instal-therm program.

5. After opening of file in Instal-therm program, to specified partitions on the drawing their definition should be assigned. In order to do that, go to the layer “Construction” and select from main menu „Edition” the command „Select all elements of type” >> Wall >> External” . All external wall on the drawing will be selected. In data table, in field “Construction type” select adequate name, that is definition of partition. It is possible to assign the constructional type to external partitions in this way only when all external walls are made of partitions of the same definition.

When external walls have different definition, click each partition separately and in the table on the right side of plan view in field „Construction type” select from a pop-up list the partition definition, for example SC-ZEW (external wall).

Proceed similarly for internal partitions, windows and doors in external and internal walls, selecting in data table adequate type of partition construction.

Horizontal partitions – floors or ceilings are to be selected by clicking the partition description on a storey plan view.

If on the storey no horizontal partitions have been entered, it is possible to complete building structure with these partitions using the key for defining of ceiling and the key for defining of floor. Horizontal partitions can be entered both as internal partitions and external partitions.

! By means of mode BLOCK – clicking the field in lower right screen corner you can lock the sheet content, so that during selection of individual walls they would not move.

Analogical operation should be performed on each storey. In this way the User will assign partitions defined in „Partitions definitions” to individual compartments.

Because other graphical compartment data, concerning ventilation and temporary temperature reduction in compartment (if such calculation option has been selected) must be still completed, further work with program should be performed in tabular editor of Instal-heat&energy program. The User should save the file on disc and go to Instal-heat&energy program.
