2.7.4 Comparison of Energy Savings
The GE frequency converter solution offers major savings compared with
traditional energy saving solutions. This is because the frequency converter
is able to control fan speed according to thermal load on the system and the
fact that the frequency converter has a build-in facility that enables the fre-
quency converter to function as a Building Management System, BMS.
The graph below illustrates typical energy savings obtainable with 3 well-
known solutions when fan volume is reduced to i.e. 60%.
As the graph shows, more than 50% energy savings can be achieved in typical
applications.
