Sound Data - AERMEC NSB Serie Manual Tecnico

Sound Power
Aermec determines the value of sound
power on the basis of measurements per-
formed in compliance with regulation 9614,
in respect with that requested by Eurovent
certification.
(1) Sound Pressure
Sound pressure in free field on a reflective
surface (factor of directionality Q=2), at 10
metres from the external surface of the
unit, using the parallel expansion method
(box-method, ISO 3744)
KEY
Operating conditions:
Evaporator water (in/out) 12/7 °C
