  2. Seasonal energy efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Seasonal_energy_efficiency...

    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.

  3. European seasonal energy efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/European_seasonal_energy...

    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 ...

  4. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    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 = 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.

  6. European Union energy label - Wikipedia

    en.wikipedia.org/wiki/European_Union_energy_label

    Example EU energy label for a refrigerator. EU Directive 92/75/EC (1992) [1] established an energy consumption labelling scheme. The directive was implemented by several other directives [2] thus most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent.

  7. Coefficient of performance - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_performance

    Less work is required to move heat than for conversion into heat, and because of this, heat pumps, air conditioners and refrigeration systems can have a coefficient of performance greater than one. The COP is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often ...

  8. Annual fuel utilization efficiency - Wikipedia

    en.wikipedia.org/wiki/Annual_fuel_utilization...

    The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...

  9. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    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 ...
