Window AC / September 1, 2018 / Babette Arsenault
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.
If you live in a college dorm studio apartment or a one-to-two bedroom apartment a window air conditioner is probably your best bet for keeping cool during the summer months. Unlike a central air conditioner a window unit can cost under $200 and will do an excellent job keeping your place cool during the dog days of summer. A window air conditioner - as the name suggests - sits on your window in a semi-permanent installation. This type of unit is designed to work straight out of the box and requires minimal hassle when installing to the window. Basically you attach the unit to your windowsill and then close the window down on top of it.
