Description
PATENTKRAV 1. Fremgangsmåde til kontrol af bakterieforhold i brugsvandsinstallationer omfattende en koldtvandsinstallation og en varmtvandsinstallati-on, hvilken fremgangsmåde sker under anvendelse af periodiske temperaturreduktioner og/eller udslamninger, kendetegnet ved, at der under en overordnet styring og på baggrund af temperaturmålinger og/eller forbrugsmålinger foretages periodevise og/eller forbrugsafhængige temperaturreduktioner, udslamninger, pasteuriseringer og/eller gennemskylninger af brugsvandsinstallationen. 2. Fremgangsmåde ifølge krav 1,kendetegnet ved, at temperaturreduktioner foretages ved, eksempelvis en gang i døgnet, at blokere varmetilførsel og/eller temperaturstyring af varmtvandsinstalla-tionen, og at en cirkulation i varmtvandsinstallationen og/eller en eventuel udskylning foretages, indtil brugsvandstemperaturen når en forud fastsat temperatur, eksempelvis ca. 20°C. 3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at udslamninger foretages ved, at der foretages en udskylning fra varmtvandsinstallationen i et forud fastsat tidsrum, indtil brugsvands-temperaturen har nået en forud fastsat værdi eller indtil der er registreret en forud fastsat værdi for gennemstrømningen af brugsvand. 4. Fremgangsmåde ifølge krav 1,2 eller 3, kendetegnet ved, at en pasteurisering foretages ved, eksempelvis en gang i døgnet, at hæve brugsvandstemperaturen, fortrinsvis målt som fremløbstempe-raturen, til en forud fastsat værdi, eksempelvis ca. 65°C, og at en cirkulation i varmtvandsinstallationen og/eller en eventuel udskylning foretages, eksempelvis i en forud fastsat tidsperiode. 5. Fremgangsmåde ifølge krav 1, 2, 3 eller 4, kendetegnet ved, at en gennemskylning af koldtvandsinstallationen foretages i en forud fastsat periode og/eller indtil der er registreret en forud fastsat værdi af gennemstrømningen og/eller indtil en forud fastsat temperatur for koldtvandsinstallationen har været underskredet i en forud fastsat tidsperiode. 6. Fremgangsmåde ifølge krav 1, 2, 3, 4 eller 5, kendetegnet ved, at der på fortrinsvis forud fastsatte tidspunkter foretages en analyse af brugsvandet, og at der på grundlag af resultatet heraf kan udsendes en alarmering og eventuelt en nedlukning af brugsvandsinstallationen, 7. Anlæg til kontrol af bakterieforhold i en brugsvandsinstallation, der omfatter en koldtvandsinstallation (1, 3) og en varmtvandsinstallation (8, 9, 10) med en varmtvandsbeholder (5), kendetegnet ved, at anlægget omfatter en central styreenhed (11), der på baggrund af temperaturmålinger (16,17, 18,19 og/eller forbrugsmålinger (23, 24) kan foretage periodevise og/eller forbrugsafhængige temperaturreduktioner, udslamninger, pasteuriseringer og/eller gennemskylninger af brugsvandsinstallationen. 8.
