What is visible from the outside of a window air conditioner is the casing, a metal box with ventilation louvres that houses the actual air conditioner. One sees a similar box for a wall-mounted air conditioner. People naturally assume they are the same. But they aren’t, and this article will explain why.
The two types share some characteristics. Both bridge the dividing line from the inside out, allowing all components to be housed in a single box. Therefore, both use indoor and outdoor air for performance. Both are designed to air condition a single room. But there are differences.
The windows are thin and best quality air conditioner in bangladesh the window unit case is designed to take advantage of that. It sits on the windowsill, with the window closed on the casing to seal the top. Side panels fill the gaps on the sides. These are also very thin so most of the sleeve is uncovered and on the outside. This allows ventilation louvres to be placed on the sides and top, allowing free air movement.
This is the main difference between the two types. The wide availability of louver space allows the unit to move large amounts of air, meaning window units can be quite powerful, up to 3 tons or 36,000 BTUs! Window air conditioners can thus be effective for very large rooms.
In contrast, the cuff of a wall-mounted air conditioner is intended for an opening through the wall. The walls vary significantly in thickness. A wall with simple sheet metal siding may be only 6 inches thick, while a brick or stone wall may be much thicker.
