ESB stands for extra special bitter. This style is known for its balance and the interplay between malt and hop bitterness. ESB stands for extra special bitter.
I have a large room with a valted ceiling 23ft.X20ft. with southern exsposure that gets lots of sun on two sides of the room. We are having 90* to 100* days for several months I needed the largest AC window unit I could find that runs on 120V. This Friidaire 15,100-BTU was the largest I could find and it works great. I can set the timer to come on three to four hours before I get home and the room is very cool when I get home. Unit runs fairly quit and works great to cool the room down as cool as you want it or can stand it.
BTU rating is the amount of heat an air conditioner can remove from a room. For a duel hose portable A/C, about 30% of that heat is the waste heat produced by the unit itself. For single hose portable air conditioner, about 50% of that heat is produced by the unit or sucked in by the unit from outside the house. portable air conditioner need about 18 inches of space on each side for it to breath as shown in this image of an installation guide. Put your hand about that distance away from the unit, if you feel air flow though your hand, that place should be open for air flow.
