Cooling system, metallurgical plant and method for operating a cooling system

摘要

The invention relates to a cooling system (1) for a metallurgical plant, with which metal products (2) can be acted upon directly by a coolant (3), comprising at least one discharge means (4) for direct loading of a metal product (2) with the coolant (3). at least one adjusting means for adjusting a volume flow of the refrigerant (3) supplied to the discharge means (4) and at least one pressure increasing means (10) for supplying the adjusting means with the refrigerant (3). In order to improve the energy efficiency of the cooling system (1) and reduce operating costs, the cooling system (1) comprises at least one evaluation means (15) arranged to take into account a refrigerant pressure (p) between the discharge means (4) and the setting means, etc to determine a coolant pressure setpoint (P). Further, the cooling system comprises at least one control means connected to the evaluation means (15) and the pressure increasing means (10) for controlling the refrigerant pressure (p) between the pressure increasing means (10) and the adjusting means to the refrigerant pressure target value (P) by appropriately driving the pressure increasing means.
