Test methods

Performance of climate control equipment is obtained by dividing the compensated thermal load between the energy consumption used to compensate the said load.

With respect to air conditioning or heat pump equipment, it is the cooling or heating power divided by the consumed energy.

In general terms, we differentiate between 2 types of performance:

• Performance obtained for and from a single operating temperature condition and the thermal load of the sample, as defined in the standard EN 14511:
  • EER - Energy Efficiency in Refrigeration mode
  • COP - Coefficient of Operating Performance in heating mode
• Those obtained by combining the EER or COP performances obtained at different temperature conditions and thermal load according to the standard EN 14825.
  • SEER - Seasonal Energy Efficiency in Refrigeration mode
  • SCOP - Seasonal Coefficient of Operating Performance in heating mode

To calculate SEER and SCOP, the hours over the year are also considered in which the device is in either of the non-active modes.
