Seasonal Efficiency of Commercial Air Conditioning Units

Until 2013, the method for measuring the efficiency of commercial air conditioning units was to use nominal values, and the efficiency would be determined from air conditioners working in fully nominal conditions. However, this is not often achieved in real life, so a more accurate method was developed to rectify this.

In 2013, the seasonal energy efficiency ratio (SEER) was developed to give a better measurement of the real-life efficiency of air conditioning systems.

What Factors Are Used to Measure Seasonal Efficiency?

A number of factors are taken into consideration to provide the seasonal energy efficiency ratio (SEER), providing a more realistic view of energy efficiency in real life conditions. They include:

  • Energy performance in different climate zones
  • Efficiency at full load and partial load capacity
  • Energy consumption in standby modes and in the auxiliary
  • Temperature fluctuations
  • Different load requirements through the seasons

These measures are tracked daily and, after one year, the seasonal efficiency data gives a far more in-depth and reliable overview of the system’s actual energy consumption. This sort of data enables consumers to take the right steps towards reducing their system’s ecological footprint.

The Law Around Commercial Air Units

The European Union issued a legislative act (Ecodesign Directive (2009/125/EC)) to set the minimum efficiency standards all energy-related products had to meet, and provided a graded system to rank products efficiency.

All commercial air conditioning units are required by the European Union’s Ecodesign Directive to display a uniform energy label. These energy labels display the energy efficiency of heating and cooling devices, allowing consumers to easily compare models.
