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.
It 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.
Domestic 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.

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.

beacause its in ur fridge
put it in the fridge
because there is holes who regenerate cold
When the fridge is not cooling due to freon leak or freon restriction.

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.
The cooling element in freezers is at the top in order to keep it its coolest. This is because in a freezer or fridge the heat travels using thermal convection. In your kettle you have a the heating element at the bottom so the water particles are less dense and rise upwards beofore cooling at the top and becoming colder denser particles that then replace thehot particles at the bottom. This cycle carries on....however in a fridge or freezer you want the particles to be colder and denser so the cooling element is at the top so it allows the particles rise then to cool faster at the top. Its basically the reverse of what you have in your kettle, that allows you to boil your water!
Really not worth the effort. You'd have to dismantle and rebuild the whole cooling system.
In this system, cooling air comes not only from the backside of the selves but also from the door side. This way the items stored in the fridge gets even colling irrespective of their location in the shelves. This technology helps is quick and even cooling of the items.
There are many places one can purchase a commercial fridge. There are both online and offline companies that can supply a range of commercial fridges such as Food Service Warehouse, MissionRS, and the Capital Cooling company.
Maybe your thinking of "tons of refrigeration" which is the cooling load of the refrigerator. Not to be confused with the volume or weight of the fridge. If you can find the insulation values (R number) of the fridge, using fairly simple HVAC equations, you can estimate the required cooling load for your desired temperature.
