Problem
Air stratification is the tendency of two or more airstreams to remain separated. This commonly occurs in central air handling units in commercial and industrial building as return and outside air are introduced into the mixing box of the air handling unit. Whether a significant temperature difference exists between the two air streams or not, these two air streams tend to remain separated due to the inherent momentum/velocity of each stream. The presence
of air stratification creates many challenges in proper design and operation of air handling units. Among the most notable problems are:
- Freeze-Stat Trips & Frozen Coils
- Poor Temperature Control Accuracy
- Insufficient Fresh Air Distribution
- Poor Economizer Operation
- Uneven Velocity Profile
Mixing: The Solution
The only way to positively address each of these issues related to air stratification is properly mixing the return and outside air streams. Blender Products, Inc. offers numerous products and services that can predictably and effectively resolve each problem.
