Intake temperature selection
IHI turbo compressors are designed to operate under the severe/tough summer conditions of ambient temperature 35°C and relative humidity 80%. Lowering the temperature and humidity will improve the drive power ratio accordingly. Therefore, energy saving effect is also obtained by using an "external air intake", sucking in cool air from outside.
The motor overload prevention function prevents air intake if the airflow exceeds the motor's maximum capacity.
Control system selection (IGV energy saving effect)
The compressor's inlet has vanes whose angles can be changed in order to reduce the impeller air intake. This is more effective than using a butterfly valve to add pressure loss in order to reduce airflow, and if the same airflow is discharged, the dynamic power can be kept tow.
