This is something that is often done when people are talking about air conditioners that they sell, as though everyone in the world knows what all of those abbreviations and acronyms mean.
However, not everyone automatically knows what EER or BTU is. With the help of this article, you will finally know what these terms mean and how they can help you in choosing the best portable air conditioner.
For starters, BTU is an abbreviation for British Thermal Unit. This is the amount of heat that is needed in order to increase the temperature one degree Fahrenheit for a pound of water. Therefore, this is a measurement of energy, and in this case that energy is heat.
You might be wondering what that has to do with your air conditioning unit. In the case of air conditioning, the BTU is referencing the ability to change the temperature of air in a certain amount of time.
To make this simple, you will want to remember that the higher the BTU rating, the easier it will be for the unit to change the air temperature.
Therefore, you now understand that an air conditioning unit that has a 12,000 BTU will cool the air of a room much faster than that of an air conditioner that only has a 10,000 BTU.
By the way, the best 10000 BTU portable air conditioner on the market today is the Whynter ARC-10WB 10,000 Btu Portable Air Conditioner. This is a terrific unit at a reasonable price. It also comes with multiple fan settings and an energy-efficient design.
As the manufacturers will tell you on their box, the size of the room has to be taken into consideration. Rooms are measured in square feet, but you also have to think about the total volume of the room, which means you might want to factor in the height of the ceiling.
Then there are the things you have to think about on your own, such as any obstructions to the circulation of air, excessive sun exposure, insulation, the temperature outside, and how cold you actually want the room to become.
So, how does all of this affect you?
Imagine that you have a room in your home that has a 10-foot high ceiling and the square footage of the room is 289 (17 x 17). By making use of the available charts, you are going to assume that you want the best 10000 BTU portable air conditioner.
However, you have to keep in mind that the chart is showing you figures for a standard room with an 8-foot high ceiling. With your 10-foot high ceiling, you are looking at an extra 20% volume of air, or the equivalent to a room that is 346 square feet. Therefore, you will want an air conditioner that is designed to handle at least 350 square feet, which would be a 12000 btu air conditioner instead of the 10000 unit.
Now you know a lot more about the BTU and how it cools down your rooms. Of course, you will still want to consider the other factors that were discussed when thinking about which BTU to get. If you want to be on the safe side, going up in BTU’s is never a bad thing. Anymore more than the minimum needed would only help to cool the room quicker, thus making the unit run less.
