Window AC / September 2, 2018 / Denise Brisette.
You can not block the air conditioner with curtains for example; otherwise the comfort will be created between the window and curtains but not in the room. Less effective in a larger room. Sometimes price is much the same as of the split-system. One must admit window air conditioners design more compact and reliable compared to split-system. Window air conditioning system consists of a single case. This so-called monoblock is mounted into the window opening or wall. The conditioner case is a big box assembled from metal plastic panels of white gray light brown or other pastel colors. All the filling of indoor and outdoor units of split-system (evaporator condenser compressor fan etc.) is inside the case. There are no any external connecting tubes.
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.
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.
Air conditioners are old-timers among climatic equipment which provide comfortable conditions for living. The first window air conditioning system was invented in America in 1930s. Such devices became widespread at once due to their simple design low price and rather high power thus making the cooling of individual rooms possible. Buy your conditioner as per the appropriate BTU. It is a measurement of energy abbreviated as BTU which stands for British Thermal Unit. For this purpose you will be required to find the correct BTU of your room. BTU is proportional to the amount of heat a window conditioner will remove from a room.
