Document Type and Number:
WIPO Patent Application WO/2023/045292
Kind Code:
A1
Abstract:
A testing method for a range hood, the method comprising: performing constant power control on a fan of a range hood according to a set power, and obtaining M performance points to be selected of the fan and the fan efficiency corresponding to each performance point to be selected, wherein the performance points to be selected are data pairs of the air volume and air pressure of the fan when the fan efficiency meets a set condition, and M ≥ 1 and M is an integer (S101); according to the set power and the fan efficiency, determining a target performance point from the M performance points to be selected, wherein the target performance point is a performance point to be selected that enables the energy efficiency level of the range hood to not be lower than a target level (S102); and determining a target operation parameter of the range hood according to the target performance point (S103). The development speed for improving the energy efficiency level of a whole range hood is remarkably increased, and the process cost and mounting cost are reduced. Also provided are a testing apparatus for a range hood, and a range hood.
