Ever since I got my portable AC, I've been wondering how I can make this hunk of junk more efficient because till this day, I have never been able to drop the temperature lower than 25° C.
This week I was making a few modifications to my room and realized the amount of air being sucked into the room but no wind was blowing in the corridor. It hit me right there that this portable AC is venting air but I never considered where the air was coming from. This leads me to the conclusion that because it's pulling air from outside at 30°C and lowering it to 25°C and it repeats this process. The door is on the opposite side of the room to the AC and the AC vents out a nearby window.
My question: Is there a proper way that the room is to be setup to allow this AC to pull air through the room efficiently.
Any suggestion would be accepted at this point, because my room is basically a construction site to me. I'll add a diagram soon to better aid in seeing the air flow that is happening.
