In the first pass, the air should adjust the internal temperature of the already significantly cooler outside temperature. Here I was therefore only right when cooler air from outside reinströhmte, so I no "seal" simply hung out the hose completely to balcony door. Inside were about 26 degrees, about 22 outside and sinking. The air creates after just half an hour a substantial increase of well-being, lowering the temperature by about 1 degree while reducing the humidity.
Then the air was to show what they can, if it is outside warmer than inside. As I said I have covered with a blanket the tube, which works great. First wanted to tinker me from a Styrofoam box with cut-out for use of the pipe, which, however, has now turned out to be unnecessary. The ceiling is simple, cheap and flexible. Amazingly, creates the PAC N81 under these less than ideal conditions quickly a pleasant chill temperature. In the first hour is loose inside the cooling to 1 to 2 degrees. You quickly get used to it and like it then even cooler, though it has long ceased sweating. Consequently, I leave to the unit a few hours, cooled down to less than 23 degrees but I can not reach, even in the evening when it is cooler outside. But is because that permanently reside in the room at least. 2 adults, a large TV is persistent and a terrarium with heaters with safety. Given, but actually remarkable what the air does. The only downside: If you switch it off, it does not take long and you sweat again. Luckily she has a thermostat that measures the current room temperature and upon reaching the desired temperature switches off the device or only circulates the air. In this mode, the device is much quieter. In cooling mode, it would be too loud for me to sleep, watch TV for it does not bother me but, even though I'm sitting hur 2 meters away from the air and thus closer than the TV.
All in all I am very satisfied, now that I no longer need to sweat. Now I can comfortably relax in the summer on my sofa after work finally. Thus, it met my expectations completely. The accessory remote control works great even from a few meters distance, line of sight is not necessary.
