How to Calculate EER

Calculating the Energy Efficiency Ratio (EER) of an air conditioner involves a straightforward formula. Here’s how you can calculate the EER:

1. Identify the cooling capacity of the air conditioner in BTUs (British Thermal Units). This information is typically found in the product specifications or label.
2. Locate the power consumption of the air conditioner in watts. This can also be found in the product specifications or label.
3. Divide the cooling capacity (in BTUs) by the power consumption (in watts) to determine the EER of the air conditioner.

The formula for calculating EER is as follows:

EER = Cooling Capacity (BTUs) ÷ Power Consumption (watts)

For example, if the cooling capacity of an air conditioner is 12,000 BTUs and the power consumption is 1,200 watts, the EER would be calculated as follows:

EER = 12,000 BTUs ÷ 1,200 watts = 10

In this case, the EER of the air conditioner would be 10.

It’s important to note that higher EER ratings indicate greater energy efficiency and lower operating costs over time. When comparing different air conditioner models, be sure to consider their respective EER values to determine which one offers the best efficiency for your needs.
