Introduction

In order to standardize the energy efficiency measurement and testing of range hoods that implement energy efficiency labeling management, JJF 1261.1-2017 The requirements of the Energy Efficiency Measurement and Measurement Rules for Energy Products are formulated. This specification is the first release. Range hood energy efficiency Metrology detection rules

1 Scope

This specification specifies the upper part of the appliance installed in household cooking stoves, stoves or similar applications. The rated voltage does not exceed Energy efficiency measurement requirements, measurement and testing procedures for 250V external exhaust range hoods (hereinafter referred to as range hoods) Measurement and testing methods, measurement results evaluation criteria and test reports. This specification is applicable to the energy efficiency measurement supervision and inspection of range hoods. The commissioned inspection can be carried out with reference to this specification. produce Units that sell range hoods can also be tested with reference to this specification. The range hood to be tested shall be the product that the producer self-tests, or the seller shall import or sell. commodity.

2 reference files

This specification refers to the following documents. JJF 1261.1-2017 energy efficiency measurement and testing rules for energy products GB/T 2829-2002 Periodic inspection count sampling procedures and tables (applicable to the inspection of process stability) GB/T 6165-2008 High efficiency air filter performance test method efficiency and resistance GB/T 17713-2011 Scope hood GB 29539-2013 Range hood energy efficiency limit value and energy efficiency rating For dated references, only dated versions apply to this specification; undated quotations The latest version (including all amendments) applies to this specification.

3 terms and units of measure

The following terms and units of measurement apply to this specification. 3.1 Total pressure efficiency totalpressureefficiency The product of the specified air volume of the range hood (7m3/min) and the total pressure value of the air standard state when the air volume is specified, The ratio of the input power of the main motor to the specified air volume, expressed as a percentage. 3.2 standby mode standbymode The range hood is connected to the power supply and provides only restart, information or status display (including clock) functions. The status of the main function is not provided. Note. The restart function refers to switching the appliance to provide the main function mode by means of a remote controller, internal sensor or timing clock. A function of the style. 3.3 Shutdown mode offmode The range hood is connected to the power supply, but does not provide any standby mode function and status of the main function. Note. When only a shutdown status indication (such as a light-emitting diode) is provided, it is also considered to be off. 3.4 standby power standbypower
