Quick Answer: How Does Fridge Work?

How does a fridge and freezer work?

That liquid is then pumped through a capillary which removes any moisture or contaminants before being sent to your fridge/freezers evaporator coils.

How does a fridge keep things fresh?

The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food.

How does a refrigerator work thermodynamics?

According to the Second Law of Thermodynamics, heat will always flow spontaneously from hot to cold, and never the other way around. A refrigerator causes heat to flow from cold to hot by inputting work, which cools the space inside the refrigerator.

How do you use a refrigerator for the first time?

In transit, your appliance gets shaken around, so it’s best to let everything settle before you plug it in. If it was transported upright, give it at least an hour before you plug it in. If it was transported on its side, turn it the right way up and leave it for at least four hours.
