GB29539-2013
The minimum allowable values of energy efficiency and energy efficiency grades for range hoods
吸油烟机能效限定值及能效等级
GB 29539-2013 is a current mandatory Chinese national standard for The minimum allowable values of energy efficiency and energy efficiency grades for range hoods. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Oct 1, 2013.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to external exhaust range hoods installed above household cooking stoves or similar appliances, with a rated voltage not exceeding 250V. It is mandatory for all manufacturers producing range hoods for the Chinese domestic market. The standard does not cover other types of kitchen ventilation systems, such as recirculating hoods. Refer to GB/T 17713-2011 for basic product definitions.
Technical requirements
The standard categorizes range hood energy efficiency into 5 grades, where Grade 1 represents the highest efficiency. The evaluation is based on several critical parameters, including full pressure efficiency, standby power, off power, and normal odor reduction degree. Products must meet the Grade 5 requirements to be permitted on the market, as this serves as the minimum allowable value of energy efficiency. Additionally, the standard defines a conservation evaluation value, which corresponds to Grade 2, intended to identify highly energy-efficient products. The standard also sets specific limits on power consumption during standby mode and off mode to minimize phantom energy loss. Compliance with these multi-parameter requirements is essential for market access.
Testing methods
Testing procedures are primarily conducted in accordance with GB/T 17713-2011 and the normative appendix of this standard. Manufacturers must verify both operational efficiency and low-power state consumption. For standby and off-mode power, two primary methods are specified: the short-term power measurement method (for stable power conditions) and the average power method (for fluctuating power conditions, utilizing either true average power or cumulative energy calculations).
FAQs
What products are regulated under GB 29539-2013?
It regulates external exhaust range hoods for household use with a rated voltage up to 250V. Recirculating range hoods are not covered by this specific standard.
What is the minimum energy efficiency requirement for market access?
The minimum allowable value corresponds to Grade 5 of the energy efficiency grades. Products failing to meet this Grade 5 threshold are prohibited from being sold.
How is standby and off-mode power tested?
Testing follows the methods in Appendix A, utilizing either the short-term power measurement method for stable readings or the average power method for fluctuating power, ensuring accurate measurement of low-power states. Measurements must be taken over a minimum of 5 minutes.
