Smoothing PV output fluctuation using cooling fan
… with electrical consumer in buildings such as cooling fan, and to make the overall current draw steadily from the system (consumer + PV output), without fast intermittency. For absorbing PV output intermittency we need a consumer which we can control its usage rapidly and smoothly; a consumer …

Error Sensor Placement for Active Control of an Axial Cooling Fan
… achievements in active noise control (ANC) for cooling fans have used near-field error sensors whose locations are determined according to a theoretical condition of minimized sound power. A theoretical point source model, based on the condition previously stated, reveals the location of …
