Problems solved by technology
[0002] Usually, when a company designs a new product, in order to obtain the energy efficiency value, it is necessary to measure the output air volume and input power of the designed prototype. If it is found that the energy efficiency value does not meet the requirements, it must be redesigned, which will be time-consuming. costly process
In addition, usually fan manufacturers have a series of motors that can match the fan blades to be tested. Due to the limitation of manpower and financial resources, it is impossible to conduct actual tests on all combinations of all motors and all fan blades to be tested, so it is not known whether new products Whether the motor used in the test and the fan blade under test are the combination with the highest energy efficiency value

Embodiment Construction
[0034] The present invention is described in further detail by the following examples.
[0035] see figure 1 , figure 2 , image 3 As shown, an electric fan energy efficiency measuring device is composed of a test room 1, an installation platform 2, a wind speed test platform 3 and a central control module. The installation platform 2 is located in the front of the test room 1, and the wind speed test platform 3 is located At the rear, the central control module is located outside the test room 1 and is electrically connected to the installation platform 2 and the wind speed test platform 3. The installation platform 2 includes a speed-regulating motor 21, a fan blade station 22 to be tested, and a fan blade installation shaft 23 and the installation shaft bracket 24, the two ends of the fan blade installation shaft 23 are respectively connected to the speed regulating motor 21 and the blade station 22 to be tested, and the installation platform 2 is also provided with a to...

The invention discloses a method for acquiring energy efficiency values of electric fans. According to the method, the rotating speed-torque curves of measured fan blades, the rotating speed-air volume curves of the measured fan blades, the rotating speed-input power curves of target motors and the rotating speed-torque curves of the target motors are acquired through a measuring device for energy efficiency values of electric fans, then, the rated input powers and the rated output air volumes of the measured fan blades are acquired, and therefore the energy efficiency values generated after the target motors are matched with the measured fan blades can be obtained. The energy efficiency values generated when the measured fan blades and a series of target motors have had by an enterprise itself are used in cooperation are accurately measured, and therefore the optimal energy efficiency ratio combination can be selected, and the purpose of optimizing the electric fan design is achieved.
Description
technical field [0001] The invention relates to the technical field of electric fan energy efficiency value measurement, in particular to an electric fan energy efficiency value acquisition method. Background technique [0002] Usually, when a company designs a new product, in order to obtain the energy efficiency value, it is necessary to measure the output air volume and input power of the designed prototype. If it is found that the energy efficiency value does not meet the requirements, it must be redesigned, which will be time-consuming. costly process. In addition, fan manufacturers usually have a series of motors that can be used with the tested fan blades. Due to human and financial constraints, it is impossible to conduct actual tests on all combinations of all motors and all tested fan blades. Whether the motor and the fan blade used in the test are the combination with the highest energy efficiency value. Contents of the invention [0003] The problem to be sol...
