Abstract
The invention relates to a monitoring method for monitoring the energy requirement of an extrusion installation (10), comprising the following steps: Setting of a balancing limit (20), in whose balancing space (22) the extrusion installation (10) is assembled, Monitoring of at least one energy flow (30) into the balancing space (22), Monitoring of a feed flow (40) of granules in the extrusion installation (10), Determining the relation between the at least one energy flow (30) and the feed flow (40).
Claims8
An extrusion method for improving energy efficiency by regulating intervention of an extrusion installation included in a balancing space set within a balancing limit, comprising the following:
- using at least one sensor installed in an extrusion installation for:
- monitoring of a plurality of energy flows into the balancing space, the plurality of energy flows comprise a cooling water flow, a cooling air flow, and an electric current flow
- monitoring of a feed flow of granules in the extrusion installation,
- determining a plurality of relations each between one of the plurality of energy flows and the fee flow individually;
- regulating, according to the plurality of relations, a member of a group consisting of:
- an air condition for the extrusion installation,
- a cooling device of the extrusion installation,
- air conditioning of a hall in which the extrusion installation is assembled,
- temperatures within the extrusion installation,
- temperatures of cooling water for the extrusion installation, and
- cooling of a product originated from the extrusion installation.
