Is it more efficient to keep a freezer in a warm room or a cold room ?

Question

does it take less energy to run a refridgerator in a cold room or a hot room ?

Answer 1

It would be better off in a cold room. The air surrounding the heat exchanger coils in the back would be cooler, making it more efficient to disipate the heat. This is also why it is recommended to locate window air conditioners and the heat exchangers of central air conditioning units on the north side of a building or in the shade. The cooler they can be kept the more efficiently they will operate.

Answer 2

The global warming is caused by: 1.Overpopulation of the planet - people are too destructive with all their cars, asphalt, trash, getting rid of nature, etc. Think, only 400 years ago all the American continent was a wonderful wild land with flowing rivers and lush meadows where wild horses played running around.... and now: it's all concrete freeways, megapolices, roaring airplanes, trucks... Animals can't cross freeways, they are locked up in small pockets of land, that cause them to die out slowly. People, just think about it. 2. The Sun has entered it's heating cycle. If you only download the Google space map and look at stars and planets around us or just open Wikipedia and read astronomy, you realize how fragile we are as species and how weird that we can survive and live only at a range between 15 to 120 F degrees. That how many planets around us don't have these opportunities for life. Earth is really a miracle. I'm surprised it's been so stable for all these billions and billions of years. It's amazing. Also a question to you all: Was Ice Age caused by humans too?? The Earth has it's own cycles of cooling down and heating up in correlation with other factors. And one day the Earth will die, well, not die but enter another stage, but humans won't survive to see it... But this will be in billions of years. By that time, actually , we will be dead anyway from all the nuclear wars. Nuclear war - this is the REAL threat to life. I'd worry more about that than the global warming. Also, another thought, if the global warming is here why there were absolutely no hurracanes in the gulf this year? They predicted something as strong as Katrina or even more devastating. But hey, where is it?

Answer 3

Cold room....

The reason behind this is, refregerators, freezers, and air conditioners all work in the same principal, evaporative cooling. ompress a gas of a form or another (freon) on one side and evaporate on the other.

In case of freezer, the compressor on compresses the gas and feeds it into evaporator on the freezer section where it evaporates. When it does, the surface temperature of the heat exchanger drops (thus cools) and takes heat from the surrounding. Then, the gas takes this heat in the piping to the outside and it goes to another heat exchanger where heat is exposed to cooler air (room air) so it loses heat.

It basically carried the heat from inside the freezer to outside. It has much more effecient heat transfer outside when the room is cooler because temperature difference is greater. This is similar to saying you have a warm milk in the glass. Which cools the warm glass faster, cool room or warm room.

The answer is cool room. Thus, freezer works better when placed in cool room.

Answer 4

Obviously a cold room is better.

That's like asking if it is cheaper to keep your house warm in the south or in the northern states.

Answer 5

Apparantly it should take less energy, if placed in a cold room. As the environment of the room is already cold.

Answer 6

i would say it depends on the seal on the freezer..take a dollar bill and shut it half way in the door..if you can remove it, it needs a new seal..try it in different spots on the door. this also works on your front door to your house.
