What is Energy Efficiency Ratio (EER)?April 27, 2016
In these energy-conscious times, more and more people are choosing to switch to an energy efficient way of running their workplace. By doing the same, not only will your green credentials improve, but you can also save money without having to compromise on functionality.
Replacing your current air conditioning unit with an efficient alternative can go a long way to achieving optimal living or working conditions. As such, it’s important to understand the terminology used by the air conditioning industry, so you can become familiar with their meanings and find the perfect unit for your application.
Here, we will explain what Energy Efficiency Ratio (EER) is and what its associated benefits are, so you can learn more about what this term means should you come across it during your search for a new air conditioner.
What is Energy Efficiency Ratio (EER)?
The Energy Efficiency Ratio (EER) of a piece of heating or cooling equipment is the ratio of the heat output (measured in BTU) to the power input (measured in watt-hour) whilst the system is in operation. The higher the ratio of an air conditioning unit compared with other systems, the more efficient it is.
How is EER calculated?
The Energy Efficiency Ratio of a heating or cooling system is usually calculated by dividing the heat output of the system by the power input.
For example, depending on your room size, a standard window air conditioner might have a 10,000 BTU rating. If this unit uses 1,200 watts of electrical energy, its rating is calculated to 8.3, as the sum of 10,000 BTU divided by 1,200 watts equals 8.3.
It’s also worth noting that the EER of a heating or cooling system requires a constant external temperature of 95 degrees, a constant internal temperature of 80 degrees and a humidity level of 50% to achieve the correct calculation.
Once this figure has been calculated, you can then compare it with other air conditioning systems to determine which has the highest ratio; the higher the EER rating, the more efficient the system is.
What are the benefits of EER?
In areas where heating and cooling systems are in high demand – such as offices and industrial workplaces – high EER ratings can quickly convert into large financial savings. Not only that, the low maintenance and long-lasting qualities of such systems means that less money is spent on repairs, replacement or maintenance costs.
