Abstract

Verfahren zum Steuern einer Kälteanlage mit einem Kühler (8) zum Kühlen von Kühlluft, wobei mittels eines einzigen Sensors (2) die Oberflächentemperatur (tK) des Kühlers (8) gemessen und über einen Korrekturfaktor aus der Oberflächentemperatur (tK) des Kühlers (8) die Kühllufttemperatur (tL) abgeleitet wird, worauf auf der Basis des gemessenen Temperaturwertes (TL) und des abgeleiteten Temperaturwertes (tK) die Kälteanlage gesteuert wird.

Method for controlling a refrigeration system with a cooler (8) for cooling cooling air, the surface temperature (tK) of the cooler (8) being measured by means of a single sensor (2) and a correction factor from the surface temperature (tK) of the cooler (8) the cooling air temperature (tL) is derived, whereupon the refrigeration system is controlled on the basis of the measured temperature value (TL) and the derived temperature value (tK).
