  • Zo werkt een koelkast

    Hebt u zich ooit afgevraagd hoe uw koelkast werkt? Bekijk de video of lees verder om meer te weten te komen over de basisprincipes van het koelproces, vertrouwd te raken met de hoofdcomponenten van een koelkast en te ontdekken wat er met koudemiddel gebeurt terwijl het zich door het koelkastsysteem verplaatst.

  • Dit doet een koelkast

    Om voedsel vers te houden, moet in de onmiddellijke omgeving van het voedsel een lage temperatuur worden gehandhaafd om de vermeerderingssnelheid van schadelijke bacteriën te verlagen. Een koelkast werkt door warmte van binnen naar buiten te leiden. Dat is de reden dat het warm aanvoelt als u uw hand aan de achterkant van de koelkast in de buurt van de metalen leidingen legt. U zult zo ontdekken hoe dat in zijn werk gaat.

     

  • Wat zijn de hoofdcomponenten van een koelkast?

    1. Compressor

    De compressor is het "hart" van een koelkast. De compressor laat het koudemiddel in het systeem circuleren, verhoogt de druk in het warme deel van het circuit en verwarmt het koudemiddel. Het is te vergelijken met het oppompen van een fietsband: u voelt de pomp warmer worden wanneer u de lucht samenperst.

    2. Condensor

    De condensor bevindt zich aan de achterkant van een koelkast en is waarschijnlijk nogal stoffig. Binnenin koelt het koudemiddel af en condenseert het, wat betekent dat het van een gas weer overgaat in een vloeistof.

    3. Verdamper

    De verdamper bevindt zich binnen in een koelkast en zorgt ervoor dat de producten in de koelkast koud worden. Als het koudemiddel door verdamping van een vloeistof overgaat in een gas, koelt het de directe omgeving, waardoor de juiste omgeving voor het bewaren van voedsel wordt gecreëerd.

    4. Capillair

    Het capillair is een dun buisje dat dient als expansieorgaan. Het vloeibare koudemiddel wordt door het capillair geleid en in de lagedrukomgeving van de verdamper gespoten.

    5. Thermostaat

    De thermostaat regelt het koelproces door de temperatuur te bewaken en de compressor in en uit te schakelen. Wanneer de sensor detecteert dat het in een koelkast voldoende koud is, wordt de compressor uitgeschakeld. Als er te veel warmte wordt gedetecteerd, wordt de compressor ingeschakeld en begint het koelproces van voren af aan.
