GB 19761-2020 Active
GB 19761-2020 Minimum allowable values of energy efficiency and energy efficiency grades for fan
Abstract
This standard specifies the energy efficiency grades, energy efficiency limits, and test methods and technical requirements for ventilators. This standard applies to general-purpose centrifugal ventilators, general-purpose axial flow ventilators, centrifugal induced draft fans for industrial boilers, centrifugal ventilators for power station boilers, axial flow ventilators for power stations, centrifugal ventilators for HVAC systems, and forward-curved multi-blade centrifugal ventilators. This standard does not apply to ducted ventilators for air conditioning, box-type ventilators, centrifugal ventilators without a casing, and ventilators for other purposes and with special structures.
