Abstract

Abstract: The characteristic of the energy efficiency test of EU water heater which is different from the national water heater standard is that the energy efficiency test needs to draw off the water, and the draw-off water is not one-time. The key of the test is to solve the control of draw-off water on the energy efficiency test. Analyzes and studies the data acquisition rate, process data processing and test process control of the test system affecting the draw-off water energy content control, puts forward the scheme and the draw-off water energy content control strategy for EU water heater energy efficiency test, and applies it to a new EU water heater energy efficiency test system. Through the test and comparative study for a water heater, the draw-off water energy content control is further verified and analyzed, and the accuracy of draw-off water energy content control reaches ±2%.

Key words: Water heater, Energy efficiency test, Energy content, European standard
