Window AC / August 25, 2018 / Babette Arsenault
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.
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.
If you choose to use a window air conditioner than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in. As you can tell by now I am not a big fan of window air conditioners. They do have a place for some people. However you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner. Central air conditioning will last much longer be quieter during operation be more efficient be more secure but the initial cost will be higher.
