would opening a refrigerator cool a room in a house?

Answer 1

A fridge is a heat pump: whatever heat it takes from the inside (at low temperature) it rejects outside at higher temperature though the vents in the back. Overall, a refrigerator heats a room; opening the door would only have it fight a heat tug of war with itself, and the heat would always win.
The only way for a fridge to cool a room would be to have it run at maximum, and then shut if off to use the "cold" inside with the door open, but that assumes all the heat released to build up this cold would have dissipated already.
So, this cannot be used for continuous cooling, unless the fridge is located with the heat vent of the back set outside of the house, then what you have is an air conditioner.

Answer 2

Yes, for a limited time. When the compressor compresses the coolant gas, the gas becomes hot. That is a function of compression. That heat is spread into the air around the compressor and behind the refrigerator. Then the compressed gas is sent into the refrigerator's insulated chamber and is allowed to expand back to its natural atmospheric pressure. That expansion of a compressed gas causes the gas to get cold. That is a function of expansion. The cold gas cools the pipe it is in and that cold pipe cools the air in the insulated chamber. The amount of head added to the gas during compression is exactly equal to the amount of heat taken out of the gas during expansion. So if you leave the door open indefinitely, the room temperature will eventually get back to the temperature of the nearby rooms of the house. The refrigerator does not have the ability to act as an air conditioner because both the compression mechanism and the cooling mechanism are in the same room. The magic of an air conditioner is that the compressor is outdoors and the expansion chamber is indoors. So the heating heats the outside world and the cooling cools the house. A simple, elegant system that a refrigerator cannot equal. But for a limited period of time, the answer to your question is "Yes" because there is cold stored in the air in the insulated chamber and in the food and the containers. That cold energy has been built up and stored over many hours before you opened the door. That cold will be transmitted to the air outside of the refrigerator into the room until the cold is fully dissipated. At that point, the heat generation and the cold generation will be nearly equal. After that, the open refrigerator will slightly heat the room. Although the heating and cooling caused by compression and expansion of the gas are equal, there is heat generated by operation of the compressor motor and the fan motor. Mayan

Answer 3

For a short time, yes. Heat would move from the room to the inside of the refrigerator, making it warmer than it was, and the room cooler than it was. If the refrigerator was turned off, it would stay that way. But if it's turned on, it would simply circulate heat from the inside to the outside, and it would then migrate back to the inside. But the refrigerator isn't perfectly efficient, so once the room reached equilibrium, its temperature would gradually increase due to the continuous addition of waste heat.

Answer 4

Nope, that is against the 2nd law of thermodynamics - stating that heat flows from hot body to a colder body (considering your refrigerator is only normal sized). Unless your entire house is an enclosed area w/ refrigeration (is that even possible? why not install an air conditioning unit instead?), the case is impossible.

But hey, that would be really cool!

Answer 5

No the room would heat the refrigerator, remember energy
flows to the cold body, not the other way

Answer 6

A fridge works by transferring heat from the inside of itself to the outside of itself. So if you opened the door, the room would be cooled by contact with the inside of the fridge, but would be heated by contact with the outside of the fridge.

Answer 7

No. Besides, plugging in 3, 7, 10, even 20 fans would cool a room better and use less energy. Think about it.

Answer 8

yes you can cool a room using a refriegerator, but it is costly and requires more energy... keep the fridge open inside the room and close all the doors and windows of the room.. but one thing you should keep in mind, the condensor and compressor parts of the fridge should be outside the room.. :)

Answer 9

Now this is where my dream invention (not yet invented) would be good.
An instantaneous window.
I open it on a HOT day in Australia, to my mother's house in English winter. Instantaneously air moves between countries.
You could also instantaneously move goods, parcels etc between countries as well.
Silly but dreamy when it's too cold or too hot.

Answer 10

no it's not possible becoz the room's temperature will heat the refridgerator.if it happens like what you say it is not necessary to buy air coolers.
