If you are looking for the Highest ISEER rating AC in India 2022 and want to know what is ISEER rating, ISEER full form, then you have come to the right place. Today I’ll tell about the best 1 ton AC in India 2022.

What is ISEER?

ISER stands for Indian Seasonal Energy Efficiency Ratio, which is used for air conditioners, refrigerators, and other electrical devices.

It‌ ‌is‌ ‌the‌ ‌ratio‌ ‌of‌ ‌the amount of heat that equipment can remove from the indoor air when operating in an active mode to how much energy the equipment consumes ‌during‌ ‌the‌ ‌same‌ ‌period.

What is ISEER Rating?

ISEER rating is determined by taking cooling seasonal total load (amount of heat removed) to the total amount of energy consumed by the air conditioner. This means ISEER equals‌ ‌Cooling‌ ‌seasonal‌ ‌total‌ ‌load‌ ‌(CSTL)‌ ‌divided by ‌Cooling‌ ‌seasonal‌ ‌energy‌ ‌consumption‌ ‌(1600 Hours in Yearly 23ºC to 43ºC )

ISEER Full Form

ISEER Full Form is Indian Seasonal Energy Efficiency Ratio

How is ISEER Calculated?

ISEER is calculated by Cooling Seasonal Total Load divided by Cooling Seasonal Energy Consumption

ISEER Formula

ISEER=Cooling Seasonal Total Load (CSTL)/Cooling Seasonal Energy Consumption (CSEC)

ISEER value is calculated for the entire year assuming a temperature profile for the year and 1600 hours of operation of the air conditioner.

What is EER?

EER stands for Energy Efficiency Ratio. The EER value is calculated by dividing the BTU (British Thermal Units) by the wattage of the air conditioner. For example, an 18,000 BTU air conditioner that uses 2,000 watts has an EER rating of 9 (18,000/2,000 = 9).

Difference Between EER and ISEER Value

As we mentioned earlier, both EER and SEER are measures of an air conditioner’s efficiency. Having a higher EER or SEER ensures a more efficient AC unit.
