What is EER and how it is important?

Energy Efficiency Ratio (EER), also commonly expressed as Energy Efficiency Rating, gives you an insight about how much cooling capacity the unit provides from a specific amount of energy used. Logically, when purchasing a new system, it would be best to pick the unit with a higher EER.

What defines energy efficiency?

Energy efficiency is using technology that requires less energy to perform the same function. Using a light-emitting diode (LED) light bulb or a compact fluorescent light (CFL) bulb that requires less energy than an incandescent light bulb to produce the same amount of light is an example of energy efficiency.

What is a good energy efficiency ratio EER?

12 or above
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.

Where is EER used?

EER can be used to tell us how many BTUs of cooling output an air conditioner will provide after using 5000 Watt Hours worth of energy, or how much energy an air conditioner will consume when transfering 60,000 BTUs of heat.

What is energy efficiency in AC?

Ideally, 5-star rated ACs are the most energy efficient and help you save the maximum money on electricity bills. These ACs consume as low as 766 watts of electricity per annum and help you save more than Rs 10,000 per annum in power bill. This rating is given by Bureau of Energy Efficiency (BEE).

What is the difference between energy efficiency and power efficiency?

Power efficiency and energy efficiency are different. Power efficiency is about doing more within a fixed capability whereas Energy Efficiency is about “making every kWh count” (to be precise).

Is 8.9 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.

Is 10.5 EER good?

Average EER as a rule of thumb, a 12.0+ EER rating for a window type aircon is considered very efficient.

What includes EER?

The EER is the ratio of output cooling energy (in BTUs) to electrical input energy (in Watt-hour). Therefore, it has dimensions of BTU/Wh. It is also noted that it is measured over time. The SEER is the ratio of output cooling energy (in BTUs) to electrical input energy (in Watt-hour).
