Due to the differences in the understanding of the standby mode and shutdown mode of the range hood energy efficiency standards by standard users, different judgments have appeared in the design and production, energy efficiency testing, and market supervision and spot checks of range hood products. This article sorts out the relevant standards for shutdown The standby and shutdown modes of different types of range hood products are analyzed and discussed to provide a reference for companies to confirm the standby mode of range hoods.
