What Are the Energy Efficiency Ratings of Air Conditioners?

>When shopping for an air conditioner, it’s natural to focus on the size and cost. But one important factor to consider is its energy efficiency rating (EER). This number tells you how many British Thermal Units (Btus) per hour it can produce. The higher the EER, the more energy efficient the air conditioner is. EERs vary from 1 to 20, with 10 being the most common. This article breaks down the different types of EERs and how they affect your decision when shopping for an air conditioner.

Basics of EER

The energy efficiency rating (EER) is the measure of the cooling capacity of an air conditioner. It’s a number that tells you how many British Thermal Units (Btus) per hour an air conditioner can produce. An EER of 10 indicates that the air conditioner can cool 10,000 Btus per hour. An EER of 12 means the air conditioner can cool 12,000 Btus per hour.EERs are generally expressed as a number from 1 to 20. The higher the EER, the more efficient the air conditioner is.The EER is calculated by measuring the amount of cooling capacity in Btus per hour and then dividing by the electric energy input in watts. The higher the cooling capacity in Btus per hour, the lower the electric energy input in watts will be.

EERs and Their Meaning

The EER is a measure of the cooling capacity of an air conditioner. The higher the EER, the more efficient the air conditioner is. The EER is a number from 1 to 20, with 10 being the most common.The EER is calculated by measuring the amount of cooling capacity in Btus per hour and then dividing by the electric energy input in watts. The higher the cooling capacity in Btus per hour, the lower the electric energy input in watts will be.The EER is useful for comparing the cooling capacity of different models of air conditioner. It’s also a good indicator of the total amount of energy that an air conditioner will consume during a typical cooling cycle.

How to calculate your EER

To calculate the EER of your air conditioner, first measure its cooling capacity in Btus per hour. Then divide the cooling capacity by the electric energy input in watts. The EER is the result.To measure the cooling capacity in Btus per hour, simply plug the cooling capacity into a chart that can be found online. The chart will tell you the EER of your air conditioner.
