¯ Determination of the sound power level: — Part 1: Air conditioners, liquid chilling packages, heat pumps for space heating and cooling, dehumidifiers and process chillers — Part 2: Heat pump water heaters According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

LWo sound power level radiated by the outdoor side. 3.2.3 Ducted units For ducted unit, the required value is the sound power level travelling into the duct. It is assessed from the sound power level radiated by the air outlet opening of the duct, corrected by the “duct end correction” factor E (see 6.2.2). LWd sound power level travelling into the (discharge or suction) duct. For the case of a ducted indoor side of a split unit: LWdi sound power level travelling into the (discharge or suction) duct of indoor unit. For the case of a ducted unit on the outdoor side: LWdo sound power travelling into the (discharge or suction) duct of outdoor unit. The sound radiated by the casing does not require any specific suffix. Use the same symbols as in 3.2.1 to specify which unit is concerned, indoor or outdoor side. SIST EN 12102-1:2018

It is then recommended to measure relative humidity or dew point instead of determining the wet bulb temperature. Suitable windshields are recommended to be fitted on microphones if they have to be affected by air velocity (above about 2 m/s) which may be produced by the unit under test or by the laboratory facilities. Adjustment shall be made to the measured sound pressure levels to compensate for any alteration in the sensitivity of shielded microphones. Above 10 m/s, windshields are usually not efficient enough and care shall be taken to reduce the air velocity (by changing the location of microphones) or to change the type of windshields. It is recommended to fit the intensity probes with windshields if they have to be affected by air velocity because they are much more sensitive to that parameter. For instance, the maximum air velocity admitted by EN ISO 9614-1 is 2 m/s. SIST EN 12102-1:2018

Unless a specific procedure for fixing the frequency of the outdoor fan(s) is specified in the manufacturer's manuals bundled with the unit, the test shall be performed at maximum fan speed obtained with the unit running within the standard rating temperature conditions plus tolerances. b For units with outdoor heat exchanger surfaces greater than 5 m2, the deviation on the air inlet dry bulb temperature is doubled. For units tested in enclosed space, care should be taken to the airflow of the unit (m3/h) which would preferably not exceed 60 times the volume of the room (m3). This upper limit indicates the microphones can be submitted to excessive air velocity. In addition, it is recommended to check the air speed through the microphone path(s) or at the different microphone positions to ensure negligible influence of air speed over the microphone(s). In the case of air source heat pumps, the evaporator shall be free of ice during the measurement. However, sound measurements are sometimes not possible due to coil frosting and stationary time running requirement. 6 Installation of the unit 6.1 General The unit shall be installed and connected up for the test as recommended by the manufacturer in its installation and operation instruction manual. In case of split or ducted units, care shall be taken to ensure that transmission of structur
