The room will warm up.

The fridge with the door left open will run pretty much continuously to try to cool the inside. Our fridge doesn't know the door is open, so it keeps running. The thermostat inside never senses that the inside has cooled, so it tells the compressor to stay on. The room will be cooled by the fridge, but remember that the compressor dumps heat out into the room all the while that it's running. And because the fridge is not 100% efficient, there will be more heat generated than there will be cooling. The result? The room will eventually warm up.

I would disagree partially with the above answer. 1) Efficiency is a term not really used for refrigerators. The term coefficient of performance is used because it can be and usually is greater than one (or greater than 100% in other words) and equals the heat removed from the inside of the fridge divided by the work input. 2) Now, if a perfect fridge was running on a Carnot cycle (no friction in the parts and other criteria) that gives the most cooling for the least amount of work, the room would still heat up as governed by the first law of thermodynamics. W=Heat from the condenser - heat from the evaporator or W+QL=QH. In this case all the terms are considered to be positive numbers. Clearly QH>QL which means the room is getting warmer.

Probably the easiest was to understand this is that work is going into the insulated room which means the overall energy and therefore temperature is going up.

What will happen when refrigerators are opened?

Cold air in the refrigerator escapes and is replaced by warm humid room air. This usually triggers the refrigerator mechanism to cool that air, if you leave the door open too long you can waste lots of electricity.


Why cant opening the door of the refrigerator will cool the kitchen?

If you have noticed the warm air blowing from behind your refrigerator, that is the heat that was in the air that is inside your refrigerator. If you leave the door open the air around the refrigerator will briefly feel cold, but it will warm back up and the food in the refrigerator will go bad.

Can a refrigerator cool down a room if left open?

No. The heat that is generated by cooling the inside is usually given off at the back of the refrigerator. If you leave the door open then everything will become room temperature.

Why should you open a refrigerator as seldom as possible?

When you leave the door open, the cool air flows out, and the warm air flows in. This means that the fridge will have to work harder to keep the food at the same temperature.

Is it ok to leave the refrigerator open?

No, for two reasons. First, the fridge door has to be closed to keep the air temperature inside the fridge cool enough to keep the foods cold and safe. Second, leaving the fridge door open causes the refrigerator to run more, costing more energy and running up the electric or gas bill.

What are some common soft magnets that can be found in your household?

The first place to look for is your refrigerator. There is a soft magnet between refrigerator door and the refrigerator body itself. You cannot see it directly but you can see it in action. When you close or open the door, you feel that the door sticks to the refrigerator body. That happens precisely because of magnets.


Can you ruin a refrigerator by opening and closing the door too often or leave door open to put away groceries?

No, you cannot ruin the refrigerator by opening and closing the door or by leaving the door open for a few minutes. Refrigerators do have a lifespan for the number of times the doors can be opened and closed before a hinge breaks or the seal is damaged, but this cycle can be in the millions - so it won't be affected with normal use. Each time you open and close the refrigerator, some cool air escapes and can mean that the compressor will have to run to get temperature back to where it should be. Leaving the door open for a few minutes does cool off the interior and things inside will begin to cool off as well. This will result in the refrigerator compressor having to run to get the temperature back down. A good refrigerator is designed to have the compressor go through these cycles many thousands of times. The only reason someone may be concerned with having the refrigerator work more would be the electric bill (it goes up, refrigerator compressors use a lot of power) or the refrigerator compressor has had problems previously.


If away for a long time is it best to turn off refrigerator and freezer or leave it running on low temperature?

If the refigerator or freezer is empty, it is best to shut it off and prop the door open to prevent mold. If the refrigerator or freezer is full, it is best to leave it running at a normal setting. It will use very little electricity if left closed.


If the refrigerator door is accidentally left open will it burn out the compressor pump's motor?

If you leave your refrigerator's door open whilst it is switched off, no harm will be done - in fact it is a very good idea to do this as it will help to prevent the mold build-up which can easily happen if it is left closed at normal room temperature with no fresh air circulation. If you leave your refrigerator's door open whilst it is switched on, the compressor pump will run continuously trying to cool the air in the room whilst at the same time pumping heat out into the same room! That is not a good idea for at least 3 reasons: * you will waste electricity 24/7 * the fridge will not cool down enough to protect any food * the compressor and its electric motor will both overheat, which will usually reduce their normal working life from 8 to 10 years to only maybe 1 year or less.

Why cant a refrigerator be used as an air conditioner as the working principle of both is same?

A refrigerator is designed to pump heat from the inside of the refrigerator to the outside of the refrigerator. Since the refrigerator is inside a room (usually a kitchen) the heat does not escape from the house that it is in. If you examine your refrigerator you will find that there is a heat exchange unit, usually in the back (although it can be on the sides) which gets hot. So if you leave the door open, any cool air that escapes into the room is more than balanced by the heat coming from the heat exchange unit in the back. An air conditioner, in comparison, is designed to pump heat from the inside of a house to the outside of a house. If, however, you were able to mount your refrigerator inside a window frame (which would be extremely difficult) and make a reasonably air tight seal, you could then leave the refrigerator door open, and use the refrigerator as an air conditioner. It would be a lot easier to just get an actual air conditioner, however.
