EER = −0.02 × SEER² + 1.12 × SEER [2] Note that this method is used for benchmark modeling only and is not appropriate for all climate conditions. [ 2 ] A SEER of 13 is approximately equivalent to an EER of 11, and a COP of 3.2, which means that 3.2 units of heat are removed from indoors per unit of energy used to run the air conditioner.
In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for refrigeration and air conditioning products, similar to the ESEER but with different load profile weighting factors, is used for part of the Building Regulations Part L calculations within the Simplified Building Energy Model (SBEM) software, and are used in the production of Energy Performance Certificates (EPC) for new ...
EER = 3.413 × COPFC(at 95 degrees F) SEER = 3.413 × COPFC(at operating points definded for the SEER testing standard) Regarding the state of Georgia having a SEER equal to the EER divided by 0.8, that cannot be. Every air conditioning system when evaluated by the test procedures for SEER and EER will provide some hopefully repeatable number.
The following table lists a number of terms that are used in the United States for residential energy audits. AFUE—annual fuel utilization efficiency; BTL—building tightness limit (building tightness) CDH—cooling degree hours (climate) CFL—compact fluorescent light; COP—coefficient of performance; CRI—color rendering index
For closed-loop systems, the ISO 13256-1 heating COP must be 3.3 or greater and the cooling EER must be 14.1 or greater. [28] Standards ARI 210 and 240 define Seasonal Energy Efficiency Ratio (SEER) and Heating Seasonal Performance Factors (HSPF) to account for the impact of seasonal variations on air source heat pumps. These numbers are ...

EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature ...
Therefore, the Seasonal Energy Efficiency Rating (SEER in the US) or European seasonal energy efficiency ratio of a reversible heat pump is typically slightly less than those of two separately optimized machines. For equipment to receive the US Energy Star rating, it must have a rating of at least 14 SEER. Pumps with ratings of 18 SEER or above ...
