2.The determination of the seasonal energy consumption and seasonal energy efficiency ratio (SEER) and seasonal coefficient of performance (SCOP) shall take into account:U.K.
(a)
European seasonal conditions, as defined in Table 1 of this Annex;
(b)
Reference design conditions, as defined in Table 3 of this Annex;
(c)
Electric energy consumption for all relevant modes of operation, using time periods as defined in Table 4 of this Annex;
(d)
Effects of the degradation of the energy efficiency caused by on/off cycling (if applicable) depending on the type of control of the cooling and/or heating capacity;
(e)
Corrections on the seasonal coefficients of performance in conditions where the heating load can not be met by the heating capacity;
(f)
The contribution of a back-up heater (if applicable) in the calculation of the seasonal efficiency of a unit in heating mode.
