Iris damper is essentially a modulating damper that precisely controls the input/output of air by mere adjustment of simple mechanism. Like aperture of a camera that controls the flow of light, Iris dampers adjusts the air flow by precise adjustment of its blades through control mechanism. This type of damper is used for modulating precise flow of air at a given condition.
PROBLEMS OF AIR STRATIFICATION In HVAC Air Handling system, air stratification resulted from the improper design inherent in moving air streams by keeping air streams of different air temperatures from mixing effectively for a long distance. A [...]
