Air Ventilation
You
can use a variety of control strategies to operate ventilation
fans. In climate control situations, the operation of the
ventilation fans is coordinated with your heating system to
maximize energy efficiency.
For
multi-fan applications, the Batavia system regulates the operation
of fans based on the current calculated ventilating requirement.
Fans can be operated individually or in groups to achieve
varied ventilation rates. Each fan can be controlled using
a simple off/on strategy, or with pulse width modulation (PWM).
With PWM control, the control system regulates the on/off
times as well as the numbers of fans operating to precisely
match the current cooling or dehumidification requirements.
This results in exceptional temperature control precision.
Fan operation can also be coordinated with evaporative cooling
pad(s) systems.
For
special applications, enhanced programs are available. These
powerful, highly flexible programs allow you to easily specify
the rules and conditions for fan operation that suit your
requirements.
