IF WE KEEP REFRIGERATOR DOOR OPEN, WILL IT ABLE TO KEEP THE ROOM COOL?

For a moment, it seems like that !
But the compressor does work to extract heat from the content and this heat is thrown out from the refrigerator.

If we keep the door open for long time then heat is taken from the room (from front portion)and thrown back to the room. So the temperature of the room remains the same. Hence, the refrigerator will not be able to keep the room cool.
