Window AC / September 5, 2018 / Lundy Brochu
Window air conditioners came to the market as a solution for people who couldnt afford or did not want central air conditioning. Because central air conditioning can be quite expensive and because many people live in small apartments central air is not for everyone. This led to the advent of window air conditioners. Window air conditioners have a hot coil and a chilled coil along with two fans. The fans blow air over these coils and they in turn suck away the heat and humidity from the room into the outside area providing clean cool air. The capacity of an air conditioner is measured in BTUs. So the size of the air conditioner plays a vital role in determining its cooling capacity.
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.
A window air conditioner in my opinion is a last resort for air conditioning your house or building. There are many down sides to window air conditioning units. There are two good things that window air conditioners have going for them. They are very inexpensive when it comes to cost per BTU of cooling. They also install very quickly and easily. That is where the good part of them ends. Window air conditioners are security risks. If a thief wants to get into your house the thin sheet metal box that holds the unit in the window can easily be pulled apart to get in through the window.
