Panasonic CS-E12QKEW User Manual

From January 2013, the energy performance calculation for air conditioning systems changed 
from an overall EU based standard of EER and COP to a new standard based on seasonal 
efficiencies of SEER and SCOP. These changes to the Energy Related Products Directive or ErP 
are designed to give consumers a better understanding of the real efficiency of air conditioning 
and heat pump systems whose nominal power rating does not exceed 12kW.
Undergoing gradual implementation from 1 January 2013 until 1 January 2019, the schedule 
for each product category is as follows:
01 January 2013: A+++, A++, A+, A, B, C, D, E, F and G.
01 January 2015: A+++, A++, A+, A, B, C, D, E and F.
01 January 2017: A+++, A++, A+, A, B, C, D and E.
01 January 2019: A+++, A++, A+, A, B, C and D.

Seasonal Energy Efficiency Ratio (SEER) – This is the overall energy efficiency ratio of the 
unit, representative of the entire cooling season. It is calculated as the annual cooling 
demand divided by the annual consumption of electricity for cooling.
Seasonal Coefficient of Performance (SCOP) - This is the overall coefficient of performance 
of the unit, representative of the entire heating season designated (the value of SCOP 
corresponds to a determined heating season). It is calculated by dividing the reference 
annual heating demand by the annual consumption of electricity for heating.
