Window AC / August 30, 2018 / Marphisa Babin
One sees a similar box for a wall air conditioner. Naturally people assume they are the same. But they arent and this article will explain why. The two types share some characteristics. Both span the dividing line from inside to outside allowing all components to be housed in a single box. Therefore both utilize both inside and outside air to perform. Both are designed to condition a single room. But there are differences. Windows are thin and the sleeve for a window unit is designed to take advantage of this. It sits on the window sill with the window closed onto the case to seal the top.
If the room is shaded then you can decrease the BTU rating you calculated with the climate control unit calculator by 10 percent however if you wish to cool a kitchen youll need to raise the rating by 4000 BTUs. When the room you are cooling is used by two or more people add six hundred BTUs per person to the rating necessary to cool the room. Before you buy the first air conditioner that fits the BTU rating necessary to cool your room make sure you have a window that will be suitable for the unit. Measure windows in the room (make sure not to block fire escapes) and make sure to buy a window air conditioner that will fit into the opening.
Side panels fill the gaps on the sides. These are also very thin so most of the sleeve is uncovered and outside. This allows for placement of ventilation louvers on the sides and top allowing free movement of air. This is the primary difference between the two types. The wide availability of louver space allows the unit to move a lot of air and this means window units can be quite powerful up to 3 tons or 36000 BTU. So window A/Cs can be effective for very large rooms. In contrast a wall air conditioner sleeve is designed for a hole through the wall. Walls vary substantially in thickness.
