Can we decrease the temperature of a room by keeping the door of a refrigerator opened?

For a short while, yes, the room will be cooler as the cold air from the fridge lowers the average temperature in the room. Over the long haul, no, the room will actually become hotter due to the fridge working hard to cool the inside of the fridge. Closed room implies closed system.

Xuefang Oelrichs Pundit. As the food inside the refrigerator loses its heator, in other words, gets colderthat heat ends up in the kitchen. Physicists call this kind of system a "heat pump. So while it's busy moving energy out of the fridge and into the kitchen, it's also drawing in more energy in the form of electricity or gas.
