The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

Abstract: This paper addresses how different control schemes for fans used to cool servers can affect energy consumption. An analytical model that includes physical parameters of a heat source/heat ...

This project implements an intelligent temperature-controlled fan system using Arduino. The system utilizes a TMP36 temperature sensor to continuously monitor ambient temperature, a servo motor ...

I've got a 120mm 120VAC fan I've been using as a desk fan, plugged directly into mains with a lamp cord. (Note for non-US readers: mains here is 120VAC, 60Hz, so I am using it at its rated specs.) I ...

In most fan systems a single fan is selected for the required system design rating. Various methods of control are employed such as dampers, variable inlet vanes, variable pitch blades, or variable ...

Fans are often used to ventilate agricultural buildings. Adjoining rooms with connecting air paths through open doors or manure channels can operate as a single room with a common negative pressure.
