Why is it unwise to try to cool a room by opening the door of the refrigerator?
To operate the refrigerator, requires a lot of energy. When the refrigerator is running, some of that energy is used to cool the interior (about 80% of said energy.) But this is not "making cold." A refrigerator cools by moving heat from inside it, to the outside. This heat is dissipated into the room by the cooling fins on the rear. The whole process happens silently and slowly, and we never notice it. So even though the inside of the refrigerator may be cold, the process of making it cold warmed up the entire room, plus 20% (the energy wasted in the conversion process.) Thus, opening the door to cool the room will never work, because the refrigerator cannot make cold, it can only move heat around. And in doing so, it itself always dissipates 20% more than the energy moved, which ultimately ends up as heat, further heating up the room. Ironically, the room would be cooler without the refrigerator in it.

How does a heat mover absorbs heat from cold air?
A good example of this process is a refrigerator. Electricity is used to power the refrigerator to keep it cool. The room that the fridge is in is warmer. Normally the warm air from the room should flow into the refrigerator until they are the same temperature. The heat mover, which is the refrigerator in this case, absorbs the heat the cooler air absorbs, and moves it back into the room. This keeps the fridge at a constant temperature.

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.
