3 Terms and Definitions

GB/T 17713-2011 define the following terms and definitions apply to this document. 3.1 Smoke fumes functional efficiency limited value minimumalowablevaluesofenergyefficiencyforrangehoods Under the test conditions specified in hood minimum allowable value of energy efficiency. 3.2 Hood evaluating values of energy evaluatingvaluesofenergyconservationforrangehoods Under the test conditions specified minimum allowable energy efficiency hood value of energy efficiency. 3.3 Standby mode standbymode Hood is connected to the power supply, provides only restart information or status display (including the clock) function, without any major State functions. Note. The restart function is through the remote control, internal sensor or time clock, etc. so that the appliance is switched to the main function of providing a functional model. 3.4 Shutdown mode offmode Hood is connected to the power supply, but does not provide any kind of standby mode state functions and the main functions. NOTE. Only shutdown, status indicators (light emitting diode) is also considered to be in shutdown mode. 3.5 Standby power standbypower Hood in the standby mode active power in watts (W). 3.6 Off power offpower Hood in shutdown mode active power in watts (W).

4 energy efficiency rating

Energy efficiency hood at full pressure efficiency, standby power, power off, reduce the degree of normality odor, grease discharge limits for classification.

8 Inspection Rules

8.1 factory inspection 8.1.1 Test program with reference to GB/T 2828.1 and GB/T 2829, determined by the quality inspection departments of their manufacturer. 8.1.2 Upon examination identified energy efficiency limit value fails to meet the requirements of Chapter 5 of the products do not allow the factory. 8.2 Type inspection 8.2.1 one of the following occurs, it should be energy efficiency limit test. a) new product trial; b) changes in product design, workmanship or materials used significantly affect its performance; c) after a lapse of more than one year of reproduction; d) factory inspection results are quite different and the last type inspection; e) quality and technical supervision department inspection requirements. 8.2.2 type test sample, every 3 pumping units, of which two trials, one spare. Two test results are in line with the requirements of this standard, the Batch of qualified; if the two do not meet the requirements of this standard, the batch to be ineligible. If there is a sample value of energy efficiency does not meet this standard Requirements, respond spare samples for testing, such as test results meet the requirements, it is judged to be acceptable; If the test result is still not meet the requirements, it is determined Ineligible.

Appendix A

(Normative) Test methods for standby and off power hoods A.1 short-time power measurement This test method is only applicable to the selected mode and power stability of the situation. If the measured power within 5min variation of less than 5% Believes that power has stabilized, in this case can be read instrument displays power values directly. The test hood is connected to the measuring instrument, and selecting a measurement mode. In the hood over at least 5min to reach the power Stable, measured by measuring power consumption, time should not be less than 5min. Power value change during the measurement is less than 5% (from the maximum observed Worth to power), power has been considered stable and 5min power value recorded directly from the end of the measuring instrument. A.2 average power law This test method is applicable to the selected mode or measurement unstable power situation. However, this method is also applicable to all modes stable situation condition. This method uses a user-selected time period, the average power or accumulated energy readings. The test hood is connected to the measuring instrument, select the measurement mode is to monitor power consumption. Average power following the "average power Law "or the" cumulative energy method "to determine. Average power method. the user selected period of time meter records a true average power for the selected period of time of not less than 5min. Cumulative energy method. measuring instrument can cumulative energy consumption of user-selected time period, the selected period of time of not less than 5min. Cumulative time Lap record should be such that the total is greater than the value of the energy and time meter (including power meter and time meter) resolution 200 times. With tired Accumulated energy value divided by the measurement time to obtain the average power. Example 1. If a time resolution of the instrument is 1s, which is required as a minimum cumulative 200s. Example 2. If a resolution of the instrument of power 0.1mW · h, which is required as a minimum cumulative 20mW · h. If more than one power cycle (such as minutes or hours) changes, the average power or accumulated energy measurements are selected Inter segment should be one or more complete cycles in order to obtain a representative average. 3102- Rights Proprietary Rights Reserved ISBN. 155 066 · 1-47366 ......
