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.
