For units with brine, the test sh
37、all be carried out with the brine specified by the manufacturer, see EN 14511-4:2013, 7.2.1. NOTE 1 For air-to-water, brine-to-water and water-to-water units, the manufacturer may declare the water temperatures levels (lower, medium, high and very high) applicable to the heating mode. NOTE 2 For com
38、parison 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 evapora

The standard rating conditions, extracted from EN 14511-2:2013, Table 3 for heating mode and specified in Table ZA.1 shall be used to determine the rated capac
40、ity (Prated), the rated power input (PCOP), the rated coefficient of performance (COPrated) and the electricity consumption (QDD, QSD) in heating mode.
