Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Wärmepumpenvorrichtung, wobei das Fluid von einem Fluidspeicher (2) vorgehalten wird, ein Temperaturfühler (4) die Temperatur des Fluids erfasst, und eine Heizeinrichtung (6) das Fluid aufheizt, und infolge einer Absenkung der Temperatur des Fluids auf oder unter einen Mindestwert eine Aufheizung des Fluids auf einen Wert oberhalb des Mindestwerts, insbesondere 64°C, erfolgt. Erfindungsgemäß ist der Wert der Mindesttemperatur (8) variabel und von einem seit einer zuvor erfolgten Aufheizung vergangenen Zeitraum abhängig.

The invention relates to a method for operating a heat pump device, wherein the fluid is held by a fluid reservoir (2), a temperature sensor (4) detects the temperature of the fluid, and a heater (6) heats the fluid, and due to a lowering of the temperature of the Fluid at or below a minimum value, a heating of the fluid to a value above the minimum value, in particular 64 ° C, takes place. According to the invention, the value of the minimum temperature (8) is variable and depends on a period of time which has elapsed since prior heating.
