What is energy efficient ratio in AC?
Energy Efficiency Ratio or EER. EER = Amount of heat removed per hour/ power consumed. conditioner. Usually, EER of an air conditioner is measured under a specific condition (35 degree C, outdoor temperature; 27 degree C indoor temperature and 50% relative humidity).
What is a good energy efficiency ratio?
Generally, an EER of 12 or above is considered energy efficient, however, when comparing two models, the one with the higher EER is more energy efficient regardless of whether or not it is above 12.
What is AC energy efficiency?
Energy Efficiency Rating Higher the star rating, the more efficient is the AC. For instance, a 5 – star split AC will consume almost 10% less power than a 4-star AC. Thus, there is a 10% difference in energy consumption with increase in just one star.
What is EER for HVAC?
The Energy Efficiency Ratio (EER) of an HVAC cooling device is the ratio of output cooling energy (in BTU) to input electrical energy (in watts) at a given operating point. EER is normally calculated with a 95 °F outside temperature and an inside (return air) temperature of 80 °F and 50% relative humidity.
Which AC is energy efficient?
Best Low Power Consumption AC with Energy rating:-
| Product Name | Energy Rating |
|---|---|
| Panasonic 1.5 Ton Wi-Fi Twin Cool Inverter Split AC | 5 Star |
| Voltas 1.4 Ton Fixed Speed Split System AC (2021 Model) | 3 Star |
| Godrej 1.5 Ton Split AC | 3 Star |

What is a good EER?
12 EER rating is an excellent energy-efficiency rating for an air conditioner. Some of the best devices can even reach more than 12 EER. The best mini split air conditioners have an extremely high 12+ EER rating (check them here).
Is a higher EER rating better?
A room air conditioner’s efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.
Which AC is more energy efficient?
Is 11.2 EER good?
The average EER rating of portable AC units is about 8.5. That means buying ones below EER 8.5 is not advisable and buying those above 8.5 is quite a smart move efficiency-wise. The most energy-efficient portable AC unit (Whynter Dual-Hose) has an EER rating of 11.2.
How is EER calculated?
The EER rating for an air conditioner is calculated by dividing the BTU (British Thermal Units) rating by the wattage. For example, a 12,000-BTU air conditioner that uses 1,200 watts has an EER rating of 10 (12,000/1,200 = 10). The higher the EER rating is, the more energy efficient the unit will be.
