By opening the door of refrigerator, we can decrease the temperature of a room.

A refrigerator works by taking heat from its interior and radiating it away from the coil at the back so the net effect of a refrigerator in a room with its door open should be no change in temperature. However, we should remember that a fridge has an electric motor in it and as all machinery is never 100% efficient there should be a heat gain from having it working. So yes opening the door of a fridge would increase the temperature of the room.
