Frequently Asked Questions
What is the model number of this condensing unit?
The model number is OP-MPYM009MY.
How is the sound spectrum generated?
It's calculated by adding the full-speed sound power levels of the compressor and fan motor per EN13215 conditions.
What are the measured sound pressures at various distances?
At 1m, the Sound Pressure (dB(A)) is 51; at 3m, it is 42; and at 10m, it is 31.
Does this spectrum account for noise reduction?
Yes, the evaluation of sound power considers the effect of noise reduction due to enclosure and insulation.
