14.6.2 Heat Exchanger Reporting

Reporting the results for the heat exchanger models is done using the Heat Exchanger Report dialog box.

Reports Heat Exchanger Set Up...

The following variable options are available for reporting:

• Computed Heat Rejection

• Inlet Temperature

• Outlet Temperature

• Mass Flow Rate

• Specific Heat

Computed Heat Rejection

To display the Computed Heat Rejection

1.   Select Computed Heat Rejection from the Options list.

2.   Select the Heat Exchanger from the selection list.

3.   Click Compute.

Figure 14.6.2: The Heat Exchanger Report Dialog Box for Reporting Computed Heat Rejection

You can write the computed data to a file by clicking the Write... button and entering the name of the heat exchanger report file in the Select File dialog box.

Inlet/Outlet Temperature

Inlet/Outlet Temperature can be reported for both primary and auxiliary fluid in the Heat Exchanger Report dialog box.

Figure 14.6.3: The Heat Exchanger Report Dialog Box for Reporting the Inlet Temperature

1.   Select Inlet Temperature or Outlet Temperature from the Options list.

2.   Select the heat exchanger from the Heat Exchanger selection list.

3.   Select either Auxiliary or Primary as the Fluid Zone.

4.   Select the appropriate boundary zone and report type from the Boundary and Report Type lists, respectively.

Note that the macro heat exchangers (unlike the dual cell heat exchanger) do not contain an auxiliary cell zone. Hence, the Boundary and Report Type fields will not appear in the dialog box if you are reporting an auxiliary inlet/outlet temperature.

5.   Click Compute.

You can write the computed data to a file by clicking the Write... button and entering the name of the heat exchanger report file in the Select File dialog box.

Mass Flow Rate

Mass Flow Rate can be reported for both the primary and auxiliary fluid in the Heat Exchanger Report dialog box.

Figure 14.6.4: The Heat Exchanger Report Dialog Box for Reporting Mass Flow Rate

1.   Select Mass Flow Rate from the Options group box.

2.   Select the heat exchanger from the Heat Exchanger selection list.

3.   Select either Auxiliary or Primary as the Fluid Zone.

4.   Select the appropriate boundary zone and report type from the Boundary and Report Type lists, respectively.

5.   Click Compute.

Note that the macro heat exchangers (unlike the dual cell heat exchanger) do not contain an auxiliary cell zone. Hence, the Boundary field will not appear in the dialog box if you are reporting an auxiliary fluid mass flow rate.

You can write the computed data to a file by clicking the Write... button and entering the name of the heat exchanger report file in the Select File dialog box.

Specific Heat

Specific Heat for the primary or auxiliary fluid can be reported through the Heat Exchanger Report dialog box. If specific heat is defined as a function of temperature, the specific heat reported will be a cell volume averaged value.

Figure 14.6.5: The Heat Exchanger Report Dialog Box for Reporting Specific Heat

1.   Select Specific Heat from the Options group box.

2.   Select the heat exchanger from the Heat Exchanger selection list.

3.   Select either Auxiliary or Primary as the Fluid Zone.

4.   Click Compute.

Useful Reporting TUI Commands

To report the results for the macro heat exchangers, you can use the following text command:

define $\rightarrow$ models $\rightarrow$ heat-exchanger $\rightarrow$ macro-model $\rightarrow$ heat-exchanger-macro-report

Specify the fluid zone $id/name$ for which you want to obtain information.

To view the connectivity of the heat exchanger groups, use the text command:
