26、-3:2013 (E) 4 1 Scope 1.1 The scope of EN 14511-1 is applicable. 1.2 This European Standard specifies the test methods for the rating and performance of air conditioners, liquid chilling packages and heat pumps using either air, water or brine as heat transfer media, with electrically driven compres

27、sors when used for space heating and cooling. It also specifies the method of testing and reporting for heat recovery capacities, system reduced capacities and the capacity of individual indoor units of multisplit systems, where applicable. This European Standard also makes possible to rate multispl

28、it and modular heat recovery multisplit systems by rating separately the indoor and outdoor units. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

31、ity test 4.1 Basic principles method of calculation for the determination of capacities 4.1.1 Heating capacity The heating 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 (

32、see Annex B). However, the heating capacity of air conditioners and of air-to-air heat pumps having a cooling capacity below or equal to 12 kW shall be determined by measurements in a calorimeter room. The heating capacity of air-to-water, water-to-water heat pumps and liquid chilling packages shall

33、 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. For steady s

34、tate operation, the heating capacity shall be determined using the following formula: HpPq c t= (1) where BS EN 14511-3:2013EN 14511-3:2013 (E) 5 PHis the heat capacity, expressed in Watts; q is the volume flow rate, expressed in cubic metres per second; is the density, expressed in kilograms per cu

35、bic metre; cpis 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 ). NOTE 2 The enthalpy change H can be di

36、rectly 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 (

37、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 effect

38、ive 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). However, the

39、cooling capacity of air conditioners and of air-to-air heat pumps having a cooling capacity below or equal to 12 kW shall be determined by measurements in a calorimeter room. The cooling capacity of air-to-water, water-to-water heat pumps and liquid chilling packages shall be determined in accordanc

40、e 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 determine

41、d using the following formula: pCPq c t= (2) where PCis the cooling capacity, expressed in watts; q is the volume flow rate, expressed in cubic metres per second; is the density, expressed in kilograms per cubic metre; cpis the specific heat at constant pressure, expressed in joules per kilogram and

42、 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 ). NOTE 2 The enthalpy change H can be directly measured instead of the term (cpx t). BS EN 14511-3:2013EN 14511-3:2013 (E) 6 The coo

43、ling 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

44、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. 4.1.3 Heat recovery capacity The heat recovery capacity of air-to-water and water-to-water heat pumps and

45、 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 hea

46、t transfer medium. The heat recovery capacity shall be determined using the following formula: tcqPpHR = (3) where PHRis the heat recovery capacity, expressed in Watts; q is the volume flow rate, expressed in cubic metres per second; is the density, expressed in kilograms per cubic metre; cpis the s

47、pecific heat at constant pressure, expressed in joules per kilogram and Kelvin; t is the difference between inlet and outlet temperatures expressed in Kelvin. NOTE The mass flow rate can be determined directly instead of the term (q x ). The enthalpy change H can be directly measured instead of the

48、term (cpx t). The heat recovery capacity shall be corrected for the heat of the pump: a) if the pump at the heat recovery exchanger is an integral part of the unit, the power calculated according to 4.1.6.3 shall be subtracted from heat recovery capacity b) if the pump at the heat recovery exchanger

49、 is not an integral part of the unit, the power calculated according to 4.1.6.4 shall be added to the heat recovery capacity. 4.1.4 Power input of fans for units without duct connection In the case of units which are not designed for duct connection, i.e. which do not permit any external pressure differences, and which are equipped with an integral fan, the power absorbed by the fan shall be included in the effective power absorbed by the unit. 4.1.5 Power input of fans for units with duct connection 4.1.5.1 The follow
