Energy saving concept & fan curves
We all know that lot of
energy is wasted in fan/pump/blower applications if not properly
designed. When we use conventional motor control system, in
which AC motor is run at full speed, the flow of gases/air
/liquid is regulated using the damper /throttle control. In
this process , substantial energy is lost in the damper/throttle.
This waste of energy can be as high as 25 to 30 % of motor
rating. Always go for reliable v/f , variable speed drives
to control the speed of fan/pump/blower, which in turn will
automatically control the flow. Hence you can eliminate the
need of damper/throttle. Your pay back period can be even
less than one year.
