— Table 4 for air-to-air units in cooling mode;
— Table 5 for water(brine)-to-air units in heating mode;

For units with brine, the test shall be carried out with the brine specified by the manufacturer,

see prEN 14511-4:2021, 7.2.1.

For air-to-water(brine), and water(brine)-to-water(brine) heat pumps, the manufacturer may declare

the water(brine) temperatures levels (low, intermediate, medium, and high) applicable to the heating

mode.

NOTE For comparison purposes between reverse cycle and non-reverse cycle units, the conditions on the

water(brine) side are given by the inlet and outlet water(brine) temperatures, possibly leading to different

water(brine) flow rates in heating and cooling modes.

The rating tests in heating mode also apply for units having evaporatively cooled condenser, which

performance in cooling mode is determined in accordance with EN 15218:2013, and which can operate

in heating mode.

The standard rating conditions, extracted from Table 3 for heating mode, shall be used to determine the

rated capacity (P ), the rated power input (P ), the rated coefficient of performance (COP ) and the

rated COP rated
electricity consumption (Q , Q ) in heating mode.

The wet bulb temperature condition is not required when testing units which do not evaporate condensate.

When using the calorimeter room method, pressure equilibrium between indoor and outdoor compartments

shall be obtained by introducing into indoor compartment, air at the same rating temperature conditions.

The pressure difference between the two compartments of the calorimeter room shall not be greater than

1,25 Pa. This pressure equilibrium can be achieved by using an equalizing device or by creating an open space

area in the separation partition wall, which dimensions shall be calculated for the maximum airflow of the unit

to be tested. If an open space is created in the partition wall, an air sampling device or several temperature

sensors shall be used to measure the temperature of the air from the outdoor compartment to the indoor

compartment.

The term “water” includes indifferently water from a river or a lake, ground water.

The test is performed with the fixed flow rate or with the ΔT obtained during the test at the corresponding

standard rating conditions for units with variable flow rate. If the resulting flow rate is below the minimum flow

rate then this minimum is used with the inlet temperature.
