Why does a room get hotter when a freezer's door is open?

Answer 1

Actually the act of cooling is removing the heat from one area and transferring it to another. Leaving the door open will cause the unit to constantly run trying to cool the inside of the freezer. With the compressor motor running constantly (creating heat) and the heat that is built up when the refrigerant compresses, this will cause the temp to rise in the room.
This is why air conditioners have a coil outside and one inside. The inside coil picks up the heat and transfers it to the outside coil where it is released.
I hope this makes sense to you.

Answer 2

The freezer's compressor compresses refrigerant. That makes it hot. Then that hot refrigerant is run through the coils on the rear of the freezer, which acts like a radiator, so that the refrigerant inside the coils is cooled by the air in the room. When the compressed refrigerant has completed its journey through the cooling coils on the outside, and is almost room temp, it flows back inside the freezer, where it is allowed to expand. When the refrigerant expands, it cools. It does this on the inside of the freezer, so that's how the freezer works.

If the door is left open, an almost equal ratio of cooling from the inside of the freezer and warming from the outside would be a wash, but it's not because the process is not 100% efficient. No machinery is. There is friction that makes it less than 100% efficient, and this is also the reason that a perpetual motion device is impossible.

Therefore, more heat is released into the room than cool air, making the room hotter.

Answer 3

The theory of heat transfer is involved.
In theory, the compressor on the freezer is removing heat from the freezer box and transferring it into the surrounding air. The open freezer door is allowing heat to go INTO the freezer at the same time, so theoretically the heat transfer should be identical and equal ------but it is NOT.

The reason is because it takes electricity (from an outside source) to operate the compressor, which is running,creating friction and EXTRA heat in the room. In doing so, the energy cycle in the room is NOT a closed system. Because the freezer door is open, the compressor keeps running, 'importing' energy and the resultant heat INTO the room.

Answer 4

When the freezer door is open, the freezer then has to work to cool the insides back down. So the compressor kicks on and works to remove the heat from the food compartment. The heat has to go somewhere, and it ends up in the room where the freezer is located.

Answer 5

If you're standing in the door of the freezer while its opened, the surface tempature of your skin is actually dropping. When you walk away, it seems hotter in the room because you're colder.

Its just like when you take a shower. If the water temp that you select is equal to the room temp, and you get out, you feel slightly colder only because of water evaporation. BUT, if you take a steaming shower and you step out into the same normal temp room, it will feel FREEZING.

I hope i didnt over explain that one! LOL!

Answer 6

A refrigerator or freezer rejects heat from inside in order to cool, With the door open it is rejecting constantly an will damage the unit by overheating!

Answer 7

Because it takes more energy to cool something down, the heat built up during the cooling process makes the room warmer

Answer 8

Freezer takes temperature from things and ,didn't you ever think of where it exhaust the absorbed temperature?
you should pay attention that the amount of Energy (and mass) is the same . and then when it freezes something ,somewhere else it will release temperature.

Answer 9

It doesn't

Answer 10

i dont know
