00:00.000 --> 00:04.772
On this process, process ventilation will measure the energy savings with dimmer

00:04.772 --> 00:17.415
A turbine generates an airflow whose speed is to be adjusted here with an anemometer

00:17.415 --> 00:24.649
We will start with a mechanical adjustment (shutter shutter)

00:24.649 --> 00:34.025
Here 2.5 m / s for 85 Watts consumed

00:34.025 --> 00:46.072
By setting 4 m / s; the consumption remains at about 85 Watts

00:46.072 --> 00:58.855
6 m / s always 85 Watts

00:58.855 --> 01:05.928
At 8 m / s a ​​slight drop to 83 Watts

01:05.928 --> 01:14.495
With 10 m / s consumption dropped: 79 Watts

01:14.495 --> 01:23.861
Mechanical regulation does not save energy!

01:23.861 --> 01:30.867
Shutter at maximum, one will adjust with the frequency (dimmer: 5 W of empty consumption)

01:30.867 --> 01:41.518
First gain: tone down! At 2.5 m / s consumption is only 53 Watts!

01:41.518 --> 01:52.107
At 4 m / s it consumes 2 times less than in mechanical: 45 Watts

01:52.107 --> 02:04.615
6 m / s for 45 Watts

02:04.615 --> 02:11.257
At 8 m / s: 56 Watts

02:11.257 --> 02:19.325
At 10 m / s: 72 Watts

02:19.325 --> 02:38.081
10 m / s = 36 km / h. The gain on a centrifugal process is notable!

02:38.081 --> 02:45.091
Both in energy and in noise nuisances :-)!

02:45.091 --> 02:55.509
Here is the inside of the process ventilation model!
