More and more often, variable frequency drives (VFDs) are used for control of fans and compressors in HVACR systems. The benefits are well documented and industry acceptance is such that most electric ...

Fan Control is the more user-friendly of the two. Its main strength lies in the ability to create fan curves based on temperature sensors—and even combine multiple sensors into a single control source ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

SwitchBot’s fan is a smart evolution for a bedroom or office fan, but not everyone needs so many features. At CNET, we’ve been looking for high-tech ways to cool off, and I think I may have found my ...
