Filling In the Energy Balance Heat Exchanger Tab
The Heat Exchanger tab contains the selection of output Attributes for the heat exchangers in the model. These Attributes hold the values for the reconciled energy measurement and tolerance, as well as statistical results, such as Solvability and Imbalance. The selected values and tolerances are the outputs from the Sigmafine Reconciliation engine.
Note that the output values you use for the parameters listed in the following table must be valid ones specified in the Element templates.
Heat Exchanger Tab
| Parameter | Description | Side | Default Attribute Name |
|---|---|---|---|
| Initial Imbalance | Quantity difference between the sum of measured flows into a balance Element and the sum of measured flows out. | Tube | ReconciledMassTubeImbalance |
| Shell | ReconciledMassShellImbalance | ||
| Variance | Variance calculated from the uncertainties of input and output flows of the balance point. | Tube | ReconciledMassTubeVariance |
| Shell | ReconciledMassShellVariance | ||
| Test 3 | Imbalance Ratio. Division of balance error by the balance variance and is a measure of the magnitude of the imbalance. | Tube | ReconciledMassTubeTest3 |
| Shell | ReconciledMassShellTest3 | ||
| Test 4 | Test 4, based on Test3, except normalized by the Balance Test Critical Value. | Tube | ReconciledMassTubeTest4 |
| Shell | ReconciledMassShellTest4 | ||
| Reconciled Residual | The Reconciled Residual is the difference between the sum of the reconciled of all inputs and the sum of the reconciled of all outputs for balance elements. | Tube | ReconciledTubeResidual |
