(b) With the water flow rate as determined for the standard rating condition. 6 Rating capacity tests 6.1 Basic principles 6.1.1 Heating capacity The heating capacity of direct exchange heat pumps shall be determined in accordance with the direct method at the water or brine heat exchanger. This shall be done by determination of the volume flow of the heat transfer medium and the inlet and outlet temperatures, taking into consideration the specific heat capacity and density of the heat transfer medium. The heating capacity shall be determined using the following formula: PH = q × ρ × cp × ∆T (1) where PH
is the heating capacity, in watts; q
is the volume flow rate, in cubic meters per second; ρ
is the density, in kilograms per cubic meter; cp
is the specific heat at constant pressure, in joules per kilogram per kelvin; ∆T
is the difference between inlet and outlet temperatures, in kelvin. The heating capacity shall be corrected for the heat from the circulating pump:  if the pump at the indoor heat exchanger is an integral part of the unit, the same power (calculated in 6.1.3.1) which is excluded from the total power input shall also be subtracted from the heating capacity; SIST EN 15879-1:2011

is the cooling capacity, in watts; q
is the volume flow rate, in cubic meters per second; ρ
is the density, in kilograms per cubic meter; cp
is the specific heat at constant pressure, in joules per kilogram per kelvin; ∆T
is the difference between inlet and outlet temperatures, in kelvin. The cooling capacity shall be corrected for the heat from the circulating pump:  if the pump at the indoor heat exchanger is an integral part of the unit, the same power (calculated in 6.1.3.1) which is excluded from the total power input shall also be added to the cooling capacity;  if the pump at the indoor heat exchanger is not an integral part of the unit, the same power (calculated in 6.1.3.2) which is included in the effective total power input shall also be subtracted from the cooling capacity. 6.1.3 Power input of liquid pumps If the liquid pump is integrated in the unit, it shall be connected for operation. When the liquid pump is delivered by the manufacturer apart from the unit, it shall be connected for operation according to the manufacturer’s instructions and be considered as an integral part of the unit. 6.1.3.1 If a liquid pump is an integral part of the unit, only a fraction of the input to the pump motor shall be included in the effective power absorbed by the unit. The fraction which is to be excluded from the total power absorbed by the unit shall be calculated from the following formula: ûη×=[]eLPqpPW (3) where η is the efficiency of the liquid pump according to EN 14511-3; ∆pe is the measured external static pressure difference as defined in EN 14511-1, in pascal; q is the nominal heat transfer medium flow rate, in cubic meters per second. 6.1.3.2 If no liquid pump is provided with the unit, the proportional
