Typical EER for residential central cooling units = 0.875 × SEER. SEER is a higher value than EER for the same equipment. [1] A more detailed method for converting SEER to EER uses this formula: 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 ...
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.
SEER, EER, and COP. Next, regarding the relationship between the SEER, the EER, and the COP (coefficient of performance), the SEER and the EER are both ratios (and ratings) for air conditioning systems. In contrast, the COP is a ratio for heat pumps and is not specifically defined by some industry standard as being a rating.
Examples of are the temperature of hot steam entering the turbine of a steam power plant, or the temperature at which the fuel burns in an internal combustion engine. T C {\\displaystyle T_{\\rm {C}}} is usually the ambient temperature where the engine is located, or the temperature of a lake or river into which the waste heat is discharged.
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 ...

For example, $225K would be understood to mean $225,000, and $3.6K would be understood to mean $3,600. Multiple K's are not commonly used to represent larger numbers. In other words, it would look odd to use $1.2KK to represent $1,200,000. Ke – Is used as an abbreviation for Cost of Equity (COE).
