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.
Today window air conditioners are becoming less popular then wall split-systems. And it happens for several reasons. These air conditioning systems are indeed much noisier than split-systems and they significantly reduce the daylight area. But besides some disadvantages window air conditioners have decided advantages. The main advantage is reasonable price. Another important factor is easiness in installation and relatively small amount of Freon in the system. Modern device models provide intensive ventilation and air conditioning and are characterized by economical operation.
The Advantages of window air conditioning units: They are cheap. Compact. Sometimes provide partial ventilation. No installation required. Easy transportation from place to place. Suitable for apartments summer cottages and offices. Window air conditioner can be easily installed in a shop on wheels. Another important advantage is long lifetime: window air conditioners seldom get to a service center mostly after many years of usage (the simpler the system - the more reliable it is). The disadvantages: High noise level. They block a part of the window stealing the daylight. The window frame must be altered.
