Nominal condition:
Indoor temperature (cooling): 27 DB(°C)/19 WB(°C), indoor temperature (heating): 20 DB(°C)/14.5 WB(°C).
Outdoor temperature (cooling): 35 DB(°C)/24 WB(°C), outdoor temperature (heating): 7 DB(°C)/6 WB(°C).
The data is measured with 7.5m equivalent pipe and 0m height difference.
The noise level will be measured in the third octave band limited values in the semi-anechoic chamber, using a real
time analyser calibrated sound intensity meter. It is a sound pressure noise level.
