Cold air is denser that warm air, so putting it at the top allows the cold air to fall downwards, displacing any warmer air back towards the cooling element. It sort of maintains a certian degree of circulation and helps keep the temperature more even. If the cooling element was at the bottom, the cold air would just stagnate in the bottom, while warmer air might still be present near the top of the refrigerator.

∙ 13y agoIt is known that the hot air rises up in the air. The same thing happens in the fridge. The relatively hot air rises up and comes in contact with the cooling element. Thus making the air cold again. In this manner a convection process is established inside the fridge, which leads to uniform cooling inside the fridge.
Hence the cooling element is found at the top of the fridge.

∙ 10y agoDomestic compression cycle refrigerators transfer heat from the inside of the cabinet to the outside while generating a few hundred Watts of additional heat in the process. An evaporator (which is usually formed from Aluminum, and resembles a radiator) is located in the freezer compartment. This is the point where heat is removed. Heat from the refrigeration compartment is transfered to the freezer for removal. The process is normally assisted by interior and exterior fans.

What is a machine cooling system called?
A machine cooling system is commonly known as a "cooling system" or "cooling mechanism." It is designed to dissipate heat generated by the machine and maintain its temperature within a prescribed operating range. Examples include air cooling systems, liquid cooling systems, and refrigeration-based systems.
What is the cooling element in the refrigerator?
The cooling element in a refrigerator is the refrigerant, which circulates through a series of coils and compressor to absorb heat from the interior of the fridge and release it outside. This process helps to maintain a low temperature inside the refrigerator to keep food fresh.
How fridge got cooling?
because there is holes who regenerate cold
How does surface area affect the cooling curve?
put it in the fridge
Why is fridge cold inside but warm outside?
The fridge is cold inside because the cooling system inside the fridge absorbs heat from the interior, keeping it at a lower temperature. The warmth outside the fridge is a byproduct of the cooling process, as the heat removed from inside the fridge is released outside. This heat release helps maintain the temperature difference needed for the fridge to stay cold inside.
Does evaporation occur in the fridge?
Evaporation can occur in a fridge when the cooling mechanism causes moisture in the fridge to evaporate. This can lead to condensation on the walls or shelves of the fridge. Refrigerators are designed to manage this moisture through systems like drainage holes or evaporator coils.
When should refrigerator freon be checked?
When the fridge is not cooling due to freon leak or freon restriction.
Why are cooling pipes of fridge are provided with thin copper fins?
The thin copper fins on the cooling pipes of a fridge help to dissipate heat more efficiently. The larger surface area created by the fins allows for better heat transfer from the refrigerant inside the pipes to the surrounding air, helping to cool down the fridge more effectively.

Why is a thermistor used in a fridge?
A thermistor is used in a fridge to measure the temperature inside the fridge. It can sense changes in temperature and send signals to the fridge's control system to adjust the cooling accordingly. This helps maintain the desired temperature for preserving food and optimizing energy efficiency.
Does refrigeration generate net cooling?
No, a fridge does not generate net cooling. If you were to run a fridge with the door open, the room would not cool down. In fact, because the motor would be running the room would actually warm up. Air conditioners have to be vented to the outside for the same reason.
How does a fridge work without a compressor?
A fridge without a compressor can use a thermoelectric cooling system, which operates using an electric current flowing through two dissimilar conductors to create a temperature difference. This temperature gradient allows heat to be transferred from the inside of the fridge to the outside, cooling the interior. However, thermoelectric fridges are usually less efficient than compressor-based ones.
Is a fridge mechanical energy?
No, a fridge does not produce mechanical energy. Instead, it uses electricity to power components such as the compressor, fan, and thermostat to create a cooling effect and maintain the desired temperature inside.
