A refrigerator and air conditioner both remove heat from a cold reservoir and into a hot reservoir Why then does an air conditioner cool a room while a refrigerator warms a room?
Both an A/C unit and a fridge pump heat from one area into another. In the A/C unit the heat is pumped out of the room and into a discharge area, normally the outside atmosphere, thus the room is cooled, wheras for a fridge the heat is pumped from inside the fridge out into the room, thus the inside of the fridge is cooled and the room is warmed. The only difference between the working of the two is that the "room" is a different side of the heat pump.

What are sodium cooled valves and how they work?
Sodium is a solid at room temperature and becomes a liquid at 97.5 degrees Celsius. Sodium cooled valves are exhaust valves in a cylinder head of an engine that open to release exhaust gasses that were formed due to combustion of fuel and air inside the cylinders and typically get very hot. The sodium cooled valves and exhaust valves filled with sodium inside, the sodium helps the valves be cooler than if they were just solid.

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.
