Where is the evaporator located in a refrigerator?

The evaporator coils sit in the back of the freezer compartment of a refrigerator and look like a radiator. The back wall of the freezer is actually the cover of the evaporator coil and can easily be opened with a screwdriver.

Why is the freezer compartment in a refrigerator placed at the upper part inside?

Freezer is normally provided at the top of the refrigerator, because density of the cold air is high compared to the hot air. In a refrigerator the air contacts with the cooling coil and gets cooling.

What is the top of the refrigerator used for?

The top shelf of your fridge should be reserved for foods that have already been cooked, or don’t need cooking, as it’s the second warmest part of the fridge, after the door shelves. Cooked meats, dinner leftovers, snacks etc are best kept on the top shelf.

What does the evaporator do in a refrigerator?

The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold. As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing food.

Why are freezers usually on top?

The reason being, the top-mounted compressor is further away from the refrigeration compartment, so your appliance doesn’t have to work harder to keep the contents inside cool. The compressor is much closer on a bottom freezer unit, so it can be harder to keep heat out.

What happens in the evaporator?

The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. This causes the refrigerant to absorb heat from the warm air and reach its low boiling point rapidly. The refrigerant then vaporizes, absorbing the maximum amount of heat.

Why the top of my fridge is not cooling?

Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won’t have a fan). Clean the fan blades and spin the fan by hand to see if it’s stuck. Plug in the fridge and make sure the fan runs when the compressor is running.

What is evaporator for refrigeration and air conditioning?

Evaporators for Refrigeration and Air Conditioning Applications. The evaporators are another important parts of the refrigeration and air conditioning systems. It through the evaporators that the cooling effect is produced in the refrigeration systems.

How does a refrigerator cool the air?

In a refrigerator the air contacts with the cooling coil and gets cooling.Because of the high density the cold air gets down and the warm air/hot air moves upward and gets cooling from the cooling coil/evaporator coil. This process is repeated.

Why is the freezer above the refrigerator?

Originally, the freezer was above because the design relied on natural convection of colder air to cascade down from the small freezer unit which was inside the refrigerator. Of course, this echoed the even earlier ice box, where the daily block of ice was placed at the top and the cool air fell, cooling the food below.

What is the difference between an evaporator and a cooling coil?

In the domestic refrigerators the evaporators are commonly known as the freezers since the ice is made in these compartments. In case of the window and split air conditioners and other air conditioning systems where the evaporator is directly used for cooling the room air, it is called as the cooling coil.
