The module for temperature optimizing of flow temperature is based on the module for extended heat consumption forecast. The temperature optimizing module permits the supplier to lower the flow temperature and thereby reduce the heat loss in the district heating network, without failing the demand for the temperature approach at the consumers.
The module calculates unassistedly the optimal flow temperature from the heat producing unit on the basis of information about the temperature on a number of critical spots in the network. Additionally, the module can estimate the various time lags from the heat producing units and out to the consumers.
Furthermore the module uses information about stored energy in the network in the form of temperature bubbles, so that the correct amount of energy is injected into or removed from the individual zones, and thereby secure, that the temperature always is correct at the consumer.
