Why should the cooling coil in a refrigerator be placed near the top of the refrigerator?

An evaporator fan located above or below the evaporator coils blows the cold air, circulating it through the freezer to keep foods frozen. A small vent in the wall of the freezer allows the cold air to pass into the refrigerator compartment, keeping the fresh food compartment cool.

Why do Refrigerators have a cooling unit at the top?

The top of the refrigerator has the cooling unit at it. When the fridge’s air becomes warm, it becomes light and rises upwards, then the cooling unit at the top cools the warm air and it settles down.

Why is the freezing unit in a refrigerator fitted near the top?

The freezing chest of a refrigerator is always fitted near the top in a refrigerator because it cools the remaining space of the refrigerator by convection currents. The air near the freezing chest cools and descends while the warmer air at the bottom rises up.

Where is the cooling coil placed in a refrigerator and why?

The refrigerator evaporator is one part of the refrigeration cycle that makes the inside of your refrigerator cold. After the refrigerant gas has gone through the condenser coils located at the back of the refrigerator, it starts to cool down and turn into a liquid.

Where should the cooling element for a fridge be and why?

Cold air sinks, so it collects at the bottom and, in a fridge freezer, the bottom shelves will be coldest. But in a fridge with an ice-making compartment at the top, it will be the top.

Why is the freezer compartment placed on top?

Freezer is the source for the refrigerator’s coldness. When the freezer is placed on top, the cold air produced from it is denser than the warmer air in the bottom. So cold air being dense sinks down and the warm air is forced to rise up so when the warm air rises up it and gets cold in the freezer.

Why is the freezing chest in a refrigerator fitted nearest stop?

Solution: Freezing chest in a refrigerator is fitted near the top, because it cools the remaining space of the refrigerator by convection current.

Where are the cooling coils in a refrigerator placed?

Condenser coils are located on the back of the fridge or across the bottom. These coils cool and condense the refrigerant. When the coils are clogged with dirt and dust, they can’t efficiently release heat.

Where is the cooling element placed in a freezer?

Where would you expect the cooling element to be placed in a freezer give a reason for your answer?

Convection from the freezer compartment cooled the rest of the refrigerator. The freezer compartment was at the top, so convection would carry the cold, denser air downward.

Why is the freezing part of the fridge is placed above the storage compartment in terms of convection currents?

so that it can cool the whole interior by setting up convection currents.

Why is the freezing chest?

Textbook solution The freezing chest of a refrigerator cools the remaining space of the refrigerator by convection currents.
