Automatic production of consumers from customer data => Validation
Customer data is transferred automatically to consumers. Thus one new consumer results from one or more customer data records. The conversion takes place according to these rules:
- The consumer is always produced at the connecting node of the customer.
- Customer data with the same consumer group and the same zone is pooled.
- The set consumer group determines which field of the customer data is converted to the consumer load figure. See Customer Tab.
If source and target are identical, no conversion is necessary. As soon as a removed quantity (amount of heat, quantity, volume) is set in the customer column, the yearly hours are needed for the conversion into the appropriate flow size (see the following table):
| Customer | Yearly hours |
|---|---|
| Connected load | - |
| Nominal mass flow | - |
| Flow rate | - |
| Current amount of heat | necessary |
| Amount of heat previous year | necessary |
| Current quantity of water. | necessary |
| Quantity of water previous year | necessary |
| Current volume. | necessary |
| Volume previous year | necessary |
| Floor space | necessary |
Depending upon type of the conversion:
- the flow and return specified temperature of the consumer group
- the yearly hours
- average material values
These are used in the following formulae. The material values for density and thermal capacity are calculated for an absolute pressure of 5 bar and the numerical mean temperature using the thermodynamics library provided.
Flow of the transformation
The transformation results only on nodes affected by data record modifications and executes these actions:
- Determine regulations on generated consumers, in order to be able to set the regulation correctly even after the deletion of generated consumers.
- Deletes the generated consumers (manually created consumers are preserved unchanged).
- Pooling of customer data according to the specified rules for new consumers.
- Re-creation of affected regulations on consumers (if necessary).
✍ Deleting customer data can to differential pressure regulations on consumers being changed over to equivalent differential pressure regulations between nodes, as long as no more consumers are present at the connection node.
