NOTE 2
The enthalpy change ∆H can be directly measured instead of the term (cp x ∆t). For the heating capacity calculation in transient operation, refer to 4.5.3.2. The heating capacity shall be corrected for the heat from the fan or pump: a) If the fan or pump at the indoor heat exchanger is an integral part of the unit, the same power (calculated in 4.1.5.2 or 4.1.6.3) which is excluded from the total power input shall be also subtracted from the heating capacity; b) If the fan or pump at the indoor heat exchanger is not an integral part of the unit, the same power (calculated in 4.1.5.3 or 4.1.6.4) which is included in the effective power input shall be also added to the heating capacity. 4.1.2 Cooling capacity The cooling capacity of air conditioners and of air-to-air or water-to-air heat pumps shall be determined by measurements in a calorimeter room (see Annex A) or by the air enthalpy method (see Annex B). The cooling capacity of air-to-water, water-to-water heat pumps and liquid chilling packages shall be determined in accordance with the direct method at the water or brine heat exchanger, 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 cooling capacity shall be determined using the following formula: tcqPpC∆ρ×××= (2) where PC is the cooling capacity, expressed in watts; q is the volume flow rate, expressed in cubic metres per second; ρ is the density, expressed in kilograms per cubic metre; cp is the specific heat at constant pressure, expressed in joules per kilogram and kelvin; ∆t is the difference between inlet and outlet temperatures, expressed in kelvin. NOTE
1 The mass flow rate can be determined directly instead of the term (q x ρ). NOTE
2 The enthalpy change ∆H can be directly measured instead of the term (cp x ∆t)” The cooling capacity shall be corrected for the heat from the fan or pump: a) If the fan or pump at the evaporator is an integral part of the unit, the same power (calculated in 4.1.5.2 or 4.1.6.3) which is excluded from the total power input is also added to the cooling capacity. b) If the fan or pump at the evaporator is not an integral part of the unit, the same power (calculated in 4.1.5.3 or 4.1.6.4) which is included in the effective power input is also subtracted from the cooling capacity.
