DSU Performance Example
This section illustrates the impact of the DSU fan on temperature stratification within a building with a 30 ft. ceiling.
Before DSU: The temperature difference between the floor and ceiling is 8°F, indicating significant stratification.
After DSU: The temperature difference is reduced to 0-2°F, demonstrating improved air circulation and an estimated 20% - 50% energy savings.
