Abstract
A fan logic evaluation device and method thereof for improving the logic evaluation of a fan. Specifically, a fan logic evaluation device is provided by first installing a fan, which corresponds to a set of parameters, in a wind tunnel device. A computer then performs a logic evaluation to convert the set of parameters into an evaluated pressure-flow curve and a measured pressure-flow curve by measuring the fan's operating conditions with the wind tunnel device. The computer further performs a logic modification to correct the logic evaluation to obtain a logic evaluation modification. The logic evaluation is then replaced by the logic evaluation modification. Finally, the above process is repeated with the same fan or a different fan.
