The invention discloses an electromagnetic compatibility testing method and system for a vehicle-mounted air conditioner. Rotating blades and a retaining blade which is coaxial with the rotating blades are arranged at an air outlet of the vehicle-mounted air conditioner, and a fan of the vehicle-mounted air conditioner blows the rotating blades to move so as to drive the retaining blade to rotate during the working process. The method comprises the following steps that a first air speed of the fan during the normal working process of the vehicle-mounted air conditioner and a second air speed of the fan in an interferential testing environment are obtained by detecting the rotating frequency of the retaining blade; an air speed threshold is set according to the first air speed; whether electromagnetic compatibility of the vehicle-mounted air conditioner in the interferential testing environment meets a preset requirement or not is judged according to the first air speed, the second air speed and the air speed threshold. According to the electromagnetic compatibility testing method, electromagnetic compatibility of the vehicle-mounted air conditioner can be tested out conveniently and accurately.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to an electromagnetic compatibility test method of a vehicle air conditioner and an electromagnetic compatibility test system of a vehicle air conditioner. Background technique [0002] The electromagnetic compatibility test of the vehicle air conditioner refers to applying a certain electromagnetic interference to the vehicle air conditioner, and judging whether the vehicle air conditioner is working in an acceptable working state by monitoring the wind speed of the vehicle air conditioner outlet, so that the electromagnetic compatibility of the vehicle air conditioner can be tested sex. [0003] At present, it is possible to judge whether the vehicle air conditioner is working in an acceptable working state by placing a radio at the air outlet of the vehicle air conditioner, and according to the change of the sound of the radio, or by placing monitoring markers such as paper stri...
