It works by pumping the heat that is inside the fridge to the outside, leaving the inside cold. If you put your had behind a fridge you can feel the heat emerging.

Do the refrigerator get the heat out or cool in?
A refrigerator is a form of heat pump. It pumps heat out of something.
Is a refrigerator an insulator?
No, a refrigerator is a type of heat pump, it takes heat out of the inside and rejects it to a heat exchanger on the back. I don't see how it could be called an insulator
Does a refrigerator change heat into cold remove thermal energy from inside the refrigerator or cause thermal energy to disappear?
Thermal energy never disappears, but it can be moved from one place to another, which is what a refrigerator does. If you examine your refrigerator you will be able to observe that there are heat exchange tubes (usually on the back) which get hot as they pump heat from the interior to the exterior of the refrigerator.
Does refrigerator affect temperature of room?
A refrigerator is a "heat pump." That is, it pumps heat out of a cold area (inside) to a warm area (the room). Thus, when working at its best, a refrigerator is a heater. However, the laws of thermodynamics assures us that it will always use more energy than it puts to work, so that extra energy will also heat the room. That is why your air conditioner (another kind of heat pump) is outdoors: if it were indoors, it would heat the room it was trying to cool!
Why refregerator is not used to cool up the rooms?
The refrigerator takes heat from one place and puts it somewhere else - it is in effect a "heat pump". What you propose can be done, if the heat the refrigerator takes out is taken outside the house. This is exactly what an air conditioner does. It is, in effect, a "refrigerator" especially adapted to cool rooms.

Is a refrigerator is an example of heat pump?
yes it pumps freon
What type of device is a refrigerator?
a heat pump that uses work to move heat

What is the difference between a refrigerator and a heat pump?
A refrigerator takes heat out of a small compartment by expanding a gas and utilising the laws of thermodynamics; a heat pump pumps warm air, heated by the sun, from a roof cavity into rooms in a houseto warm them and pumping the cold air into the roof to be heated.

How does a refrigerator freezer remove thermal energy?
thermal energy never disappears but, it can be moved from one place to another which what a refrigerator does. on the back of a refrigerator there are heat exchange tubes which get hot as they pump heat from the interior to the exterior of the refrigerator. -------------------------------------------------------------------------------------------------------- you can thank me by subscribing to my youtube channel (MyChinman) i post comedy and other skits :)
What has the author G A Hewett written?
G. A. Hewett has written: 'Mechanical heat pump (vapour compression refrigerator)'
What a heat engine does What a heat mover does?
A heat engine converts thermal energy to mechanical energy. Examples of a heat engine is a refrigerator, heat pump, and carnot cycle. A heat mover transfers heat from one object to another.
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.
