Abstract
A central air conditioning unit with a blower and feed duct is provided with a filter unit between the blower and the air outlet into the space applied with the conditioned air. The filter unit has both a sorption filter and a suspended filter and is constructed and arranged to form a sound barrier, i.e. a sound-damping or sound-blocking system.
Claims20
An air conditioning system for a space adapted to be occupied by people, comprising:
- a central air conditioning unit for conditioning room air, said central air conditioning unit having a blower for displacing treated room air;
- at least one duct connected to said blower and communicating with said space for delivering the treated room air to said space;
- at least one outlet passage communicating with said duct and provided with an air outlet opening into said space for delivering said treated room air thereto;
- and
- between said blower and said outlet passage, at least one filter unit traversed by the treated room air, said filter unit comprising at least one suspended material filter and at least one sorption filter for removing contaminants from air, said filters in said filter unit being constructed and arranged to form a sound barrier in which said filters function as sound barrier elements.

- at least one outlet passage communicating with said duct and provided with an air outlet opening into said space for delivering said treated room air thereto;
- and
- between said blower and said outlet passage, at least one filter unit traversed by the treated room air, said filter unit comprising at least one suspended material filter and at least one sorption filter for removing contaminants from air, said filters in said filter unit being constructed and arranged to form a sound barrier in which said filters function as sound barrier elements, said filters being formed as air deflectors for deflecting air through flow passages between filter walls so that air traverses said filter walls, then is deflected through said filter passages and emerges through said filter walls whereby said conditioned air undergoes a velocity reduction in traversing said filter walls and an acceleration in said passages.
