Blijf kalm onderweg: de fysica achter de autokoelkast

Denk er eens over na. Een autokoelkast is een apparaat waarmee je koude drankjes of snacks kunt nemen tijdens het rijden door woestijnen of kamperen in het wild. Deze draagbare koelunits worden steeds populairder bij reizigers, ontdekkingsreizigers en iedereen die tijdens een lange reis een verfrissend drankje of wat te eten wil. Maar hoe doe je dat?Auto Koelkastwerk en wat maakt ze uniek?

Hoe werken ze?
Compressor Technologie
Car Refrigerator are based on the use of compressors just as it happens with home refrigerators. The compressor refrigerator used in cars uses a refrigerant that circulates within an enclosed system. When compressed, this fluid gets hot and then cooled as it moves through condenser coils. The heat from inside the fridge is absorbed by the evaporating fluid thereby chilling its content.

Thermo-elektrische koeling
Car Refrigerator is thermoelectric cooling in which the Peltier effect comes into play. In this case, the flow of electric current between two dissimilar metals causes one side of them to cool down while making the other hot. Nonetheless, this kind of cooler is less efficient than compressor models though it’s silent and requires minimal maintenance.

Draagbaarheid en gemak
The portability aspect has been taken care of properly in Car Refrigerator because they have been made compact hence quite easy to carry along if need be unlike those very big ones at home.. Some models also come with inbuilt castor wheels
