Window AC / September 18, 2018 / Jacqueline Bizier.
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.
To help make that decision more clear I will explore some of the positives and negatives of the two major options. Ductless split type units are also becoming more of an option. I will do another article on that option. To include that in this article would just be more confusing. So for now we will just look at window air conditioners and central air conditioning. Central air conditioning is the best way to go if you already have a central hot air heating system already installed in your house or building. The advantage that you have is that you already have the air handler or blower part already installed.
The answer is It depends on the wall thickness. Sleeve specifications for some window air conditioner manufacturers include the maximum wall thickness before it will cover part of the louvers. For example Amanas 18000 BTU models have a max of 8.5 inches. If the wall thickness is at or below that these models can be used in as a wall air conditioner without adversely affecting function. So whats the problem if the wall covers a little of the louvers? Two things: 1) restriction of air movement and therefore reduced efficiency and 2) these units pull air in very powerfully. Cut wall edges could become loose allowing material to be sucked into the unit and potentially causing damage.
When cooling such a device reduces the humidity in the room. There are certain advantages in it for example in a hot afternoon or after rain when the humidity reaches its maximum 100% and the dehumidification is up to 30-60% it facilitates thermoregulation of the body. Window air conditioners are able not only to cool the air. More expensive and modern models have remote control and can operate in the heating and cleaning mode. They have a wide range of operating temperatures - an average from 18 to 43°C. Powerful differently directed air flow evenly distributes across the area.
