Commission Regulation (EU) No 813/2013Dangos y teitl llawn

1.

For the purposes of compliance and verification of compliance with the requirements of this Regulation, measurements and calculations shall be made using harmonised standards the reference numbers of which have been published for this purpose in the Official Journal of the European Union, or using other reliable, accurate and reproducible methods that take into account the generally recognised state-of-the-art methods. They shall meet the conditions and technical parameters set out in points 2 to 5.

2.

General conditions for measurements and calculations

(a)

For the purposes of the measurements set out in points 2 to 5, the indoor ambient temperature shall be set at 20 °C ± 1 °C.

(b)

For the purposes of the calculations set out in points 3 to 5, consumption of electricity shall be multiplied by a conversion coefficient CC of 2,5.

(c)

Emissions of nitrogen oxides shall be measured as the sum of nitrogen monoxide and nitrogen dioxide, and expressed in nitrogen dioxide.

(d)

For heaters equipped with supplementary heaters, the measurement and calculation of rated heat output, seasonal space heating energy efficiency, water heating energy efficiency, sound power level and emissions of nitrogen oxides shall take account of the supplementary heater.

(e)

Declared values for rated heat output, seasonal space heating energy efficiency, water heating energy efficiency, sound power level and emissions of nitrogen oxides shall be rounded to the nearest integer.

(f)

Any heat generator designed for a heater, and any heater housing to be equipped with such a heat generator, shall be tested with an appropriate heater housing and heat generator, respectively.

3.

Seasonal space heating energy efficiency of boiler space heaters, boiler combination heaters and cogeneration space heaters

The seasonal space heating energy efficiency η_s shall be calculated as the seasonal space heating energy efficiency in active mode η_son , corrected by contributions accounting for temperature controls, auxiliary electricity consumption, standby heat loss, ignition burner power consumption (if applicable) and, for cogeneration space heaters, corrected by adding the electrical efficiency multiplied by a conversion coefficient CC of 2,5.

4.

Seasonal space heating energy efficiency of heat pump space heaters and heat pump combination heaters

(a)

For establishing the rated coefficient of performance COP_rated or rated primary energy ratio PER_rated , the sound power level or emissions of nitrogen oxides, the operating conditions shall be the standard rating conditions set out in Table 3 and the same declared capacity for heating shall be used.

(b)

The active mode coefficient of performance SCOP_on or active mode primary energy ratio SPER_on shall be calculated on the basis of the part load for heating Ph(T_j), the supplementary capacity for heating sup(T_j) (if applicable) and the bin-specific coefficient of performance COPbin(T_j) or bin-specific primary energy ratio PERbin(T_j), weighted by the bin-hours for which the bin conditions apply, using the following conditions:

• the reference design conditions set out in Table 4;

• the European reference heating season under average climate conditions set out in Table 5;

• if applicable, the effects of any degradation of energy efficiency caused by cycling depending on the type of control of the heating capacity.

(c)

The reference annual heat demand Q_H shall be the design load for heating Pdesignh multiplied by the annual equivalent active mode hours H_HE of 2 066.

(d)

The annual energy consumption Q_HE shall be calculated as the sum of:

• the ratio of the reference annual heating demand Q_H and the active mode coefficient of performance SCOP_on or active mode primary energy ratio SPER_on and

• the energy consumption for off, thermostat-off, standby, and crankcase heater mode during the heating season.

(e)

The seasonal coefficient of performance SCOP or seasonal primary energy ratio SPER shall be calculated as the ratio of the reference annual heat demand Q_H and the annual energy consumption Q_HE .

(f)

The seasonal space heating energy efficiency η_s shall be calculated as the seasonal coefficient of performance SCOP divided by the conversion coefficient CC or the seasonal primary energy ratio SPER, corrected by contributions accounting for temperature controls and, for water-/brine-to-water heat pump space heaters and heat pump combination heaters, the electricity consumption of one or more ground water pumps.

5.

Water heating energy efficiency of combination heaters

The water heating energy efficiency η_wh of a combination heater shall be calculated as the ratio between the reference energy Q_ref of the declared load profile and the energy required for its generation under the following conditions:

(a)

measurements shall be carried out using the load profiles set out in Table 7;

(b)

measurements shall be carried out using a 24-hour measurement cycle as follows:

• 00:00 to 06:59: no water draw-off;

• from 07:00: water draw-offs according to the declared load profile;

• from end of last water draw-off until 24:00: no water draw-off;

(c)

the declared load profile shall be the maximum load profile or the load profile one below the maximum load profile;

(d)

for heat pump combination heaters, the following additional conditions apply:

• heat pump combination heaters shall be tested under the conditions set out in Table 3;

• heat pump combination heaters which use ventilation exhaust air as the heat source shall be tested under the conditions set out in Table 6.
