Outdoor temperature(cooling): 35℃ DB/24℃WB, outdoor temperature(heating): 7℃ DB/6℃WB The data is

measured with 7.5m equivalent pipe and 0 m 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.
