Abstract

Abstract: According to the fan-air duct characteristic curve, the law of changing of the fan system depending on the duct resistance is analyzed, as well as the relationship between air volume, power and revolution speed and other parameters on the premises of constant revolution speed and constant air volume based on the experimental data, and from which a constant air volume control method based on fan power checking is raised. The error of the static pressure auto-identified by this method can be maintained within 4%, and within 6% for air volume.

Key words: Ceiling ducted type indoor units, Static pressure, Constant air volume, Power

CLC Number:

TM925.12
