Can a room be cooled by leaving the door of refrigerator open?
No, leaving the door of a refrigerator open will not cool a room, but will actually make the room hotter. A refrigerator cools its own interior by pumping heat to the heat exchange coils in the back (some models do not have exposed heat exchange coils, but the sides or back of the refrigerator have coils just underneath them, and they get hot). Those heat exchange coils pump heat into the room. Since the process is not 100% efficient, the amount of heat produced includes a certain amount of waste heat. As a result, pumping heat from one part of the room to another part of the room results in a net increase in heat.
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.
Where does the energy come from which makes the pipes at the back of a fridge warm?
The energy comes from the heat taken from the heat/energy inside of the refrigerator/fridge. A fridge takes heat energy from inside the fridge and dumps it outside the fridge into the the pipes on the back of the fridge and into the room.
How does a refrigerator freezer remove thermal energy?

Do the refrigerator get the heat out or cool in?
A refrigerator is a form of heat pump. It pumps heat out of something.
What is the function of the insulation refrigerator?
It keeps heat from outside the refrigerator from getting into the refrigerator.
Takes heat from food and moves it outside through coolant pipes?

Can a kitchen be cooled by leaving the door of the refrigerator open?
No, although the short-term effect would be for the refrigerator air / freezer air to mix with and cool the air in the room.The function of refrigerator is a heat exchanger; it removes heat from the inside of the fridge and pumps it to the outside of the fridge.If we open the refrigerator door, it will remove the heat from the air that mixes inside, but then will exchange the heat back into the kitchen. That's why the room can't be cooled for a long period. In fact, due to waste heat, the room could become warmer once the refrigerator contents have reached room temperature.

What is the function of the evaporator in a refrigeration or air-conditioning unit?
A refrigerator works by evaporating the coolant inside the refrigerator thereby absorbing heat. The evaporated coolant is pumped outside of the refrigerator and compressed to make it liquefy and give up its heat then returned to be evaporated again.
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.
What causes the rumbling in the pipes when the heat starts up in a steam heat system?
I'm not familiar with rumbling in pipes, but the clanking of pipes when the heat starts up is a result of the pipes expanding because of the heat. Heat causes the metal to expand slightly, and the joints creak and clank when the heat makes its way through the pipes.
Do the refrigerator get the heat out or cool in?

How is a refrigerator an example of a heat mover?
Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.
