For the same piece of equipment, SEER will always be higher than EER. We can consider it as a real-time every EER. This is calculated by the input of electricity divided by the cooling it creates. A Short Consumer's Guide From ASM. So for instance, an air conditioner with a value of SEER-23 will be far more efficient than a unit with a rating of SEER-14. SEER can be misleading. EER = Output cooling in BTUh / input electrical energy in Wh EER = 1.12 * SEER - 0.02 * SEER 2. For instance, in Santa Clarita where average summer high temperatures might be 93 degrees. Therefore any EER to SEER calculation contains a potentially larger measurement error. Never compare the EER of one unit to the SEER value of another; they don’t correlate! The only difference between the two ratings (SEER and EER) is that EER is calculated under one set of conditions. The Energy Efficiency Ratio (EER) is a value showing the efficiency of a system at peak load capacity. In this article, we will explain what SEER is, what EER is, and finally when to use SEER vs EER. If you read the section on a unit’s SEER value, then you know that SEER is a good approximation of a unit’s efficiency if the average summer temperature in your area is around 83 degrees, but can be misleading if you live in Southern California or the South. In general, if you are a homeowner then I would use the SEER value as a means of comparing units to one another if you live in a more moderate climate, and I’d use a unit’s EER value if you are looking at a window AC unit or if you live in an arid climate like the Mojave Desert. Since 2006, the Federal Government requires a minimum SEER rating of SEER-13 for all new air conditioners, but an older AC might be lower. SEER can be used to compare one AC unit to another directly and is most commonly encountered when looking at large, central air conditioning units. What we might call a peak summer day for most of the country. The value won’t be the same if you’re installing the unit at an area with different average air conditions.

Heat Pump Temperature Ranges. value for EER is normally measured at 35 o C (95 o F) of outside dry bulb temperature, and 27 o C (80 o F) of inside dry bulb temperature. Simply put, SEER is a means of estimating how much energy your new unit will use in a year, accounting for seasonal changes. Seasonal energy efficiency ratio, the American definition and calculation of seasonal energy efficiency ratios; References But when it comes to SEER vs EER, there are some very specific instances in which to use each. At the current minimum, EER must be at least 8.7. As such, EER is more effective if you live in an arid climate that is always hot, or if you are making some kind of calculation. If your area is hotter, however, then subtract 2 points from a unit’s SEER rating for every ten degrees above 83 that is the average temperature for your area. On air conditioner’s specification sheets we usually get EER rating (many times without SEER rating). Now that you know about energy ratings, you can start shopping for more energy efficient air conditioners. Watts To Amps Converter (With 120V Examples), Convert kW To Amps: Kilowatt Ampere Calculator + 3 Examples.
