Einführung
Driven by the global carbon neutrality goal, the energy efficiency standards of household appliances continue to upgrade. According to statistics from the International Energy Agency, household refrigeration equipment accounts for more than 15% of residential electricity consumption, of which the average power of traditional electric fans is 50-100W. Modern ventilation equipment manufacturers have successfully reduced the energy consumption of high-end products to the 15-30W range through technological innovations in three dimensions: material science, motor engineering, and intelligent control, achieving a qualitative leap in energy efficiency while maintaining the same air supply volume. This technological evolution not only changes the product performance curve, but also reshapes the market competition landscape.
