Abstract
An air conditioning system suitable for automotive application is disclosed, in which the noise in the frequency range of about 1 kHz to 2 kHz is reduced. At least a sound absorbing member is arranged over the portions extending from a turning section of an air path where the air blown under pressure from a blower impinges and changes direction toward a heat exchanger, i.e. from the spiral end of a scroll casing to the front of an evaporator.
