Why is the freezer at the top of a refrigerator instead of at the bottom?
You don't require a fan as the cold air from the freezer cools the contents of the fridge as it falls to bottom of the cabinet thermodynamically.
Why is a freezer compartment at the top of a refrigerator?
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!
Why is refrigerator warm at bottom and cold at top?

If you leave the fridge in your kitchen open for 10 minutes after an hour is the room warmer or colder than it would have been had you not?
Warmer. A fridge works by transfering heat from inside the fridge to the coils out the back of the fridge. Leaving the door open is the same as pulling water out the bottom of a water cooler and pouring it back in the top. The transfering of heat cancels itself out. The fridge will stay running longer trying to keep the inside cold when the door is left open. This extra running time from the motor is the major source of the added heat to the room.

Why does water pool up and leak out of the bottom of your fridge and how can you fix it?
There is a drain point at the back of your fridge at the bottom. This is probably clogged. Remove the gunk out of it, and it should be as good as new. Helen

About Refrigerators with Bottom Freezers?
Though refrigerators with bottom freezers can be convenient, as the freezer allows more of the inside of the fridge to be at eye level, they're more expensive and a bottom freezer tends to hold less. Other than that, their maintenance is pretty much the same as top freezer refrigerators. Spills inside the fridge or freezer should be wiped up at once. An open box of baking soda should be put in both the fridge and freezer to absorb odors. It should be replaced every three months. Foods in the freezers should be stored in freezer bags, which should be dated. The coldest parts of the freezer are against the walls or the bottom of the compartment and items should have enough space between them for air to circulate.
