Both the refrigerator and the freezer have fans to keep it at cold temperatures.
PV=RT;
A compressor raises the pressure of the gas volume V and temperature rises. A fan blows away the heat into the room. Then the gas pressure is dropped in the refrig cold room and the temperature drops in the cold room, PV=RT. The heat in the cold room heats up the gas and the volume goes to the compressorr again, ec,etc,etc.
Refrigeration works by drawing heat away from the unit. It does this through a process of evaporation.

To keep food cold that needs to be kept cold.
Dense gas is pumped through small holes within a metal tube, by a motorized "compressor." When this gas makes contact with the metal on the inside, it has a cooling effect and the metal absorbs the heat from the air on the outside of the tube. Once the heat has been absorbed, this air is pumped in, or cycled through the fridge and freezer to keep things cold.
Any freezer needs to be kept closed as much as possible if you wish for it to remain cold. However a chest freezer will not warm up as fast as an upright freezer. This is because the cold air in the freezer is heavier than the air outside of the freezer. When you open an upright freezer the cold air "falls" out, this can't happen with a chest freezer.
If you have a refrigerator that needs to be repaired, look at the simple things before getting a new refrigerator. Make sure there is enough coolant in the system to keep it cold and from not freezing up. If the freezer will not keep things frozen, take everything out clean the inside as well as the door of the freezer. Then set the temperature to the middle. In the summer condensation builds up on the door and will not keep the freezer cold.

A refrigerator or freezer works by removing heat from the interior compartment using a refrigeration cycle. This cycle involves a compressor, condenser, evaporator, and expansion valve. The refrigerant absorbs heat inside the compartment, then releases it outside, keeping the interior cool.

Go to Home depot or Canadian tier. Get le fridge. Go to Walmart. STOCK IT WITH THEM WAFFLES >:D
A cold one! Lol! OK, it doesn't matter what refrigerator you get, it atleast keep things cold!
My freezer is at the bottom. The freezer being at the top isn't universal, it was just a common design for a time.
The best way to keep something cold is to place it in a cooler that is filled with ice. You can also place things underground to keep them cool or place them in a refrigerator.
An ice box is literally what it says it is, a box that has ice in it. The ice kept the food cool and it had to be replaced on a regular basis, usually daily. A refrigerator uses a compressor and gas cycle to keep the contents cold.
A freezer is colder than a refrigerator because it’s designed to keep food frozen at around -18°C (0°F), which stops bacteria and spoilage much more effectively than a fridge, which only cools to about 1–4°C.
I would assume a freezer since they're meant to keep things frozen. Also, "a cold place" is subjective.
