New Energy Efficiency Ratings
Nominal versus seasonal efficiency
Previously up until 2013, the air conditioning industry used a ‘nominal’ ratio for cooling “Energy Efficiency Ratio” (EER) and heating “Coefficient of Performance” (COP), however this resulted in a significant gap between predicted performance and what is actually achieved by the air conditioning / heat pump systems.
Nominal efficiency gives an indication of how efficient an air conditioner is when operating at full load in nominal conditions (not often achieved).
To rectify this, a more accurate method – the “Seasonal Efficiency’ Ratio” (SEER) – has now been developed, which provide a better measure of the real-life energy efficiency of air conditioning / heat pump systems.
Seasonal efficiency gives an indication of how efficient an air conditioner is when operating over an entire cooling or heating season (giving a more realistic efficiency measure).
Seasonal Energy Efficiency Ratio (SEER) & Seasonal Coefficient of Performance (SCOP)
The new seasonal energy efficiency ratio (SEER) & seasonal coefficient of performance (SCOP) take into account a number of factors, which together provide a much more realistic view of energy efficiency in real life conditions, including:
- Energy performance in different climate zones
- Efficiency at partial load capacity as well as full load
- Energy consumption in auxiliary and stand by modes
- Different load requirements through the seasons
