What does a refrigerator do?
Then, how does the refrigerator work?
The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator. 2. When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. The refrigerant absorbs the heat inside the fridge, cooling down the air.
Secondly, why do we keep some food in a refrigerator? We refrigerate food to keep bacteria, yeasts, and molds from the favorable temperature they need to grow. The moisture-control available in many refrigerators also helps slow the deterioration of foods, so that two of the three favorable situations for microorganism growth are eliminated.
Also Know, how does a refrigerator work thermodynamics?
According to the second law of thermodynamics heat cannot spontaneously flow from a colder location to a hotter area; work is required to achieve this. Similarly, a refrigerator moves heat from inside the cold icebox (the heat source) to the warmer room-temperature air of the kitchen (the heat sink).
Can we turn off refrigerator for long period of time?
Refrigerators and freezers are endurance athletes. They have to cool food and keep it fresh 24/7. There are times when you need to switch them off for an extended period of time. You can leave the refrigerator and freezer on if you are gone for less than 4 weeks.
