Through the Wall Functionality
Air conditioners can be installed in a wall, as opposed to in a window. An exterior wall has one face to the outside of a home and one face inside the home. Through-the-wall air conditioning units fit through a hole in the exterior wall, using a sleeve that supports the weight of the unit, to cool a single room in the home.
Through-the-wall air conditioners function by exhausting heat and humidity from the room to the outside as a single, self-contained unit. The air maneuvers through coils in the unit, which is then cooled by the compressor component using refrigerant, that transitions from a low-pressure gas to a high-pressure liquid as it distributes cold air into a room in a cycle.
Choosing a through-the-wall air conditioner
When it comes to choosing a through-the-wall air conditioner, there are three important things to keep in mind.
First, customers need to figure out the thickness of the exterior wall, which narrows down the types of air conditioners they can purchase.
Second, customers need to properly consider BTUs (British Thermal Units) contained by the unit for their room based on the fact that oversized units cause cold air to bounce off the wall back onto itself, interfering with the thermostat and compressor, and create 2-3 minute on/off compressor cycles not long enough to effectively cool a room. It is recommended that for a 165 Sq. Ft. room, for instance, up to 5,200 BTUs are required; a 500 Sq. Ft. room, on the other hand, requires up to 10,000 BTUs; and a 1,500 Sq. Ft. room requires between 22,000-25000 BTUs.
Third, customers need to consider plug type in the room: either voltage or amperage. Many air conditioning units come with 125V/15A plugs that can be used in most rooms. However, some larger units require more than 125V/15A so customers have to consult an electrician to upgrade the circuitry in their rooms.
Pros and Cons
Through-the-wall air conditioning units are energy-efficient, inexpensive, offer a large range of capabilities, and save customers precious window space. On the other hand, the units do not cool a whole home, (tough corners are hard to reach), have to be maintained more than once a year, and requires professional installation for creating a hole in an exterior wall.
The sleeve is the device that holds the air conditioner in the wall. There are two types of sleeves: a slide-out chassis sleeve, or a through-the-wall sleeve. Slide-out chassis air conditioning units are ideal for walls 8in thick or less. They vent through the sides and back. Slide-out chassis units include both the air conditioner as well as the sleeve. If replacement is required, customers need to buy replacement models that fit exactly into that particular slide-out chassis sleeve. Through-the-wall sleeves are purchased separately from the unit, and they come with a grille. The units vent through the rear. For replacements, customers can purchase any rear venting, or through-the-wall, air conditioner that fits into the existing through-the-wall sleeve.
