Blower Balance (patented) |
What
it does...
The automatic blower balance (ABB) module provides the function
of balancing or nulling the supply and exhaust blower flow
rates automatically (see Establishes
Initial Balance and Recovers
from a Balance Disruption below).
This feature speeds startups and eliminates the need to
train operators to balance blowers. Only one setting change
is necessary to increase or decrease air exchange rate.

Establishes
Initial Balance...
During startup, finding the right balance conditions can take
considerable time for a less experienced operator. The patented
ABB system monitors the balance and adjusts the supply blower
until it achieves the balance condition. In this case, the
supply blower is flow matched with the exhaust blower, then
the final balance is achieved.

Recovers
from a Balance Disruption...
In this case, where the bubble is too big,
slowing the inlet blower to help reduce bubble size is done
automatically. This condition can occur during startup and
during size reductions. After the bubble reaches final size,
the blowers are rebalanced.
