Seasonal efficiency
What is seasonal efficiency?

Seasonal Efficiency

Seasonal efficiency is a new way of measuring the true energy efficiency of heating and cooling technology, over an entire year. This new measure gives a more realistic indication of the energy efficiency and environmental impact of a system.

The new method of rating energy efficiency is driven by the EU’s Energy Related Products (ErP) Directive (the Eco-design Directive) which specifies the minimum Eco-design requirements that manufacturers must integrate into their energy-using products by 2013.

Seasonal efficiency demands a new rating system for heating and cooling products, which must be used by all manufacturers. These are:

  • The Seasonal Energy Efficiency Ratio (SEER) value in cooling 
  • The Seasonal Coefficient of Performance (SCOP) value in heating 

New seasonal ratings

The new seasonal ratings reflect a heat pump’s true energy consumption, based on its energy efficiency over an entire year. SEER and SCOP measure annual energy consumption and efficiency in typical day-to-day use. In the longer term, they take into account temperature fluctuations and standby periods to give a clear and reliable indication of the typical energy efficiency over an entire heating or cooling season. 

Daikin products comply with the ErP because they are designed for seasonal efficiency. As a result, they are more energy efficient and therefore emit fewer CO2 emissions. Daikin has a full range of air conditioning products optimised for the new seasonal efficiency ratings.
