Claims (5)

  1. Wärmemedium-Zirkulationssystem (100), umfassend:
    einen Kältemittelkreislauf (110), in dem ein Kompressor (111), ein nutzungsseitiger Wärmetauscher (112), eine Expansionseinrichtung (113) und ein wärmequellenseitiger Wärmetauscher (114) ringförmig verbunden sind und ein entflammbares Kältemittel verwendet wird;
    ein Luftgebläse (117) zum Zuführen von Luft zu dem wärmequellenseitigen Wärmetauscher (114);
    ein Gehäuse (140), das wenigstens den Kältemittelkreislauf (110) und das Luftgebläse (117) aufnimmt;
    eine elektrische Heizvorrichtung (143), die auf einer Oberfläche einer Bodenplatte des Gehäuses (140) vorgesehen ist; und
    eine Steuervorrichtung (130),
    dadurch gekennzeichnet, dass die Steuervorrichtung (130) dazu konfiguriert ist, den Betrieb des Luftgebläses (117) und die Aktivierung der elektrischen Heizvorrichtung (143) gleichzeitig zu starten, und so zu steuern, dass die Leistungsaufnahme der elektrischen Heizvorrichtung (143) für eine vorbestimmte Zeit ab dem Beginn der Aktivierung der elektrischen Heizvorrichtung (143) geringer ist als die Leistungsaufnahme in einem stabilen Zustand, wodurch eine Oberflächentemperatur der elektrischen Heizvorrichtung (143) so eingestellt wird, dass sie niedriger ist als ein Flammpunkt des entflammbaren Kältemittels.
  2. Wärmemedium-Zirkulationssystem (100) nach Anspruch 1, wobei
    eine Leistungsdichte der elektrischen Heizvorrichtung (143) gleich 2 W/cm2 oder weniger ist, und
    die Steuervorrichtung (130) die Leistungsdichte so steuert, dass sie während der vorbestimmten Zeit kleiner als 1 W/cm2 ist.
  3. Wärmemedium-Zirkulationssystem (100) nach Anspruch 1 oder Anspruch 2, wobei die vorbestimmte Zeit eine Zeit ist, bis ein vom Luftgebläse (117) erzeugtes Luftvolumen ein vorbestimmtes Luftvolumen oder mehr erreicht.
  4. Wärmemedium-Zirkulationssystem (100) nach einem der Ansprüche 1 bis 3, umfassend:
    einen Leckagesensor, der ein Austreten des entflammbaren Kältemittels in dem Gehäuse (140) detektiert, wobei
    wenn der Leckagesensor das Austreten des entflammbaren Kältemittels detektiert, die Steuervorrichtung (130) den Betrieb des Luftgebläses (117) fortsetzt und die Aktivierung der elektrischen Heizvorrichtung (143) stoppt.
  5. Wärmemedium-Zirkulationssystem (100) nach einem der Ansprüche 1 bis 4, wobei das entflammbare Kältemittel Propan oder ein gemischtes Kältemittel ist, das Propan enthält.
