Really need help with a small bedroom layout please!

I will include images of the dimensions of my room with annotations for the door, closet and window. I don’t have exact measurements for those things but my room is 3mx2.7m.

The only things in my room are my desk (160cm L x 60cm W) and my bed (191.7cm L x 139.4cm W) which I will also include photos of with dimensions. It may be hard to work with but I am really bad with these things and really need some help.

I’ve been wanting to get a portable air conditioning unit for my bedroom but my current room setup won’t allow for me to put the vent out my window and I have no idea what to do. Any suggestions or advice or anything at all would be greatly appreciated; thank you so much in advance!
