Efficiency ratings mastery: Know-thy-EER, SEER, COP, and various others
Various terms like EER (Energy Efficiency Ratio), SEER (Seasonal Energy Efficiency Ratio), COP (Coefficient of Performance), etc. tend to overwhelm anyone attempting to evaluate the operation-performances and energy-economical paradigms of cooling and heating systems. Each in its own right reflects the usage of energy and cost-effectiveness but knowing how to convert them plays a vital role in making correct choices.
In this blog post, we will walk you through some of the most common conversions, including EER to SEER, EER to kW/Ton, SEER to EER, etc. In addition, we provide a handy EER to SEER conversion table along with how these standards reflect energy savings along with environmental benefits.

1.EER(energy Efficiency Ratio): It is an index for the efficiency of refrigeration accomplished at a certain temperature level, mostly around 95°F.
2,SEER(Seasonal Energy Efficiency Ratio): It is more like EER very specifically, but it takes the average in overall cooling season.
3.COP(Coefficient of Performance): Usually employed in heat pumps, it compares efficiency in heating.
Why conversions?
There are several national and regional systems of measurement. COP may sometimes be more relevant for European systems, while SEER is usually the measurement used in the U.S. Conversions will allow you to compare systems, gauge energy savings, and make sure that your system meets local codes.
Conversions from one measure to another for the sake of performance description
1. EER to SEER
While EER we generally use for efficiency measurement, SEER offers seasonal readings that give a broader study approach. From EER to SEER, generally, one can arrive at:
SEER= EER×0.85
2. EER to kW/Ton
For one ton of heat that must be removed, kW/Ton indicates how many watts of power had to be supplied; that is, the following expression:
kW/Ton= 12 ÷ EER
3. SEER to EER
EER can also be obtained from SEER as indicated:
EER= SEER×1.17
4. EER to SEER2
SEER2 is based on newer testing procedures. So with this conversion:
SEER2= EER×0.90
5. CEER to SEER
CEER (combined energy efficiency ratio) is for window air conditioners. To convert it to SEER:
SEER= CEER×1.02
6. EER to COP
The COP for heating or cooling systems is expressed as:
COP=EER/3.412
7. SEER to COP
With similar conversion:
COP=SEER/3.255
8. EER to SCOP
The SCOP factor describes heating systems:
SCOP= EER×0.293
9. IEER to SEER
IEER is the integrated energy efficiency ratio that represents part-load performance. SEER can be expressed as:
SEER=IEER×1.10

SEER to SEER2 Converter:
Unit tested on SEER perhaps is going to face comparison against the recently endorsed system with SEER2 rating. This can be done with the help of some converters which show SEER units in an equivalent form of SEER2 rating so that they can be compared fairly and squarely.
23.7 SEER Equivalent:
23.7 SEER is an efficient rating; it produces good cooling in relation to input energy. However, how much does 23.7 SEER stand for in SEER2 terms?
23.7 SEER Equivalent SEER2:
Considering the rather rigorous testing methods of SEER2, a SEER rating board that generates a 23.7 SCFSEER could well be downgraded very slightly to a SEER rating at around 22.5 to 23.0.
23.7 SEER Equivalent SEER2 inverter:
Inverter-driven air conditioners are known for providing cooling very much in accordance with requirements, with therefore a very high efficiency particularly at part-load conditions. Thus, a system rated at 23.7 SEER would maintain a SEER2 rating of around 22.5 to 23.0 or better owing to the technical sophistication of these systems that was apparently coincident with the SEER2 testing requirements.
Practical Application
Saving Costs: Conversion like SEER to COP and conversion EER to SEER can be exercised to calculate energy savings and ascertaining if upgrading to a higher efficiency system is worth the investment altogether.
Comparing Systems: EER-to-SCOP or the CEER-to-SEER might help you be critical at different genres of systems, say mini-split or HVAC, relevant to your requirement.
Regulatory Compliance: Most regions have set standards of efficiency summarized in SEER or COP. Thus, these conversions would prove handy applying mandatory standards.
Closing Notes:
Learn to shift your gear between metrics such as EER, SEER, and COP, SCOP, and CEER scores so that you can make better choices for the cooling and heating systems. Whether you use them for comparing systems, estimating the effect of energy savings, or investigating new technologies, these are crucial metrics to grasp.
