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, and which can operate in heating mode. The standard rating conditions, extracted from Table 3 for heating mode and specified in Table ZA.1, shall be used to determine the rated capacity (Prated), the rated power input (PCOP), the rated coefficient of performance (COPrated) and the electricity consumption (QDD, QSD) in heating mode.

4.2 Rating conditions
For the rating tests, the appropriate test conditions shall be applied in accordance with:
— Table 3 for air-to-air units in heating mode;
— Table 4 for air-to-air units in cooling mode;
— Table 5 for water-to-air and brine-to-air units in heating mode;
— Table 6 for water-to-air and brine-to-air units in cooling mode;
— Tables 7 to 10 for water-to-water and brine-to-water units in heating mode, depending on the
temperature applications;
— Table 11 for water-to-water, brine-to-water, water-to-brine and brine-to-brine units in cooling
mode;
— Tables 12 to 15 for air-to-water in heating mode, depending on the temperature applications;
— Table 16 for air-to-water and air-to-brine units in cooling mode;
— Table 17 for liquid chilling packages with remote condenser;
— Table 18 for liquid chilling packages for heat recovery condenser;
— Table 19 for air-cooled multisplit systems and modular air-cooled multisplit systems in the heating
mode;
— Table 20 for air-cooled multisplit systems and modular air-cooled multisplit systems in the cooling
mode;
— Table 21 for modular heat recovery air-cooled multisplit systems;
— Table 22 for water-cooled multisplit systems and modular water-cooled multisplit systems in the
heating mode;
— Table 23 for water-cooled multisplit systems and modular water-cooled multisplit systems in the
cooling mode;
— Table 24 for modular heat recovery water-cooled multisplit systems.
— Table 25 for process chillers
For units with brine, the test shall be carried out with the brine specified by the manufacturer,
see prEN 14511-4:2015, 7.2.1.
For air-to-water, brine-to-water and water-to-water heat pumps, the manufacturer may declare the
water 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 side are given by the inlet and outlet water temperatures, possibly leading to different water 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, and which can operate in
heating mode.
