Abstract The theory of energy efficiency testing system of electric fans was researched in order to obtain the accurate and credible measuring data. Moreover, the method of air volume test was described mainly. System control, data collection, storage and translation were achieved by computer, the computer and programmable logic controller are linked by communication interface RS232. The methods of air volume and energy efficiency measurement were given clearly, and the uncertainty of measurement result was evaluated.
