What is ISEER rating?

Before investing in an AC, I knew that I wanted an AC that would not only keep me cool but also be energy-efficient. As I explored various options, I came across the term "ISEER" on the product labels. I had no idea

what is ISEER in AC so I

began researching and discovered that Indian Seasonal Energy Efficiency Ratio is referred to as ISEER. It is a rating system used to assess an AC's cooling performance over the course of an entire season. Let me tell you more about it.

What is ISEER rating in AC?

The Indian Seasonal Energy Efficiency Ratio (ISEER) is an advanced way of assessing air conditioners that takes into account variations in India's higher temperatures and assigns a rating in accordance.  Based on a weighted average of the performance at outside temperatures between 24 and 43 degrees C and Indian weather data, ISEER measures the energy efficiency of air conditioners.

According to the Indian Weather Data Handbook, 2014, 65% of the yearly hours have a temperature above 24 degrees Celsius (5778 out of 8760). This is based on the weather profiles of 54 main cities. In India, air conditioners have up till now been tested in accordance with IS 1391 at a standard working temperature of 35 degrees Celsius outside. Manufacturers are granted a star rating on the basis of the test results they have supplied, as measured against the aforementioned criterion. This is w

hat is ISEER rating for AC.

How is ISEER calculated?

The ratio of the equipment's total annual energy consumption to the total annual heat that it can remove from the indoor air when it is used for cooling in active mode is known as the ISEER.

The national climatic zone bin hours, the bin temperature range of 24 to 43°C, and the annual cooling operating hours of 1600 form the basis of the ISEER evaluation technique.

I hope now you understand

what is ISEER in AC.

By now I think everyone has heard about star ratings in home appliances. While buying products I heavily reply to star-rated appliances. If a product has 5 stars, I think of purchasing it because it will help me a lot in saving on electricity bills. I have done my research on star-rated appliances and from there I have come across the term EER and ISEER. So, let me share with you what is ISEER in AC in detail.

What is ISEER rating?

The Bureau of Energy Efficiency (BEE) has a grading system known as Energy Efficiency Ratio (EER). This grading is given to home appliances such as air conditioners, refrigerators, and other electrical appliances. Appliances are rated in BTU (British Thermal Unit). BTU is generally used to understand how AC will work. BTU tells how fast an AC can cool the room.

Since the temperature in India varies from state to state the EER process helps to calculate the performance of the appliances. This in turn helps to determine how much AC will consume electricity. The BEE is also known as the EER rating standard which is called ISEER in India.

So, what is the formula of ISEER?

ISEER = Cooling seasonal total load (CSTL) / Cooling seasonal energy consumption (CSEC). 

This ratio is used to give star ratings to the AC. I hope you know what is ISEER in AC now.
