Cooling outside airwill be drawn through the assembly and delivered to theoccupied zone via standard ceiling or floor diffusers.Although slightly less efficient in terms of the airmovement path this model does have the distinctadvantage of having more space (due to the physicallocation) which also then allows installation of silencers toattenuate incoming noise.
