Abstract

Die Erfindung betrifft ein Verfahren zur Sicherung von Flüssigkeitskreisläufen oder von Flüssigkeit fördernden Leitungen, insbesondere von Heizungsanlagen oder Brauchwasserleitungen, gegen Frostschäden bei dem bei Unterschreiten einer vorgegebenen Temperatur der Flüssigkeit oberhalb des Gefrierpunktes der Flüssigkeit durch ein Öffnen des Flüssigkeitskreislaufes die Flüssigkeit wenigstens zu einem Teil aus dem Flüssigkeitskreislauf abgelassen wird. Die Erfindung betrifft weiterhin eine Frostschutzanlage für einen Flüssigkeitskreislauf oder für Flüssigkeit fördernde Leitungen, insbesondere zur Durchführung des Verfahrens wobei die Anlage wenigstens einen Temperatursensor zur Bestimmung der Flüssigkeitstemperatur, ein Belüftungsventil, ein Flüssigkeitsablaßventil und eine Überwachungs-/Steuereinheit umfaßt.The invention relates to a method for securing liquid circuits or of liquid conveying lines, in particular of heating systems or Service water pipes, against frost damage when falling below one predetermined temperature of the liquid above the freezing point of the Liquid by opening the liquid circuit at least the liquid is partially drained from the liquid circuit. The invention relates also a frost protection system for a liquid circuit or for liquid promotional lines, in particular to carry out the method, the Plant at least one temperature sensor for determining the Fluid temperature, a vent valve, a fluid drain valve, and a Monitoring / control unit includes.
