Cooling A Room

[Pavan Dave]

In my house, my room is the only one that does not get its share of cool air when the AC is turned on. After having a professional look at it, he said something about the position of my window towards the sun as well as the fact that my room is the last on the line to get the cool air.

My father said that he is up for me figuring out some way to cool my room. Without buying an external AC unit [that hangs out of my window] I was wondering if anybody has any ideas or knows anything about this type of stuff so that I can mod my room? Any ideas or suggestions would be appreciated because I have no idea where to start for my research except off of others' (who have some knowledge possibly about this field) knowledge.

EDIT: I have a ceiling fan, and some other fans in my room keeping me cool right now but all that does is circulate the warm air inside my room.

Thanks for your help,
Pavan Dave.
