The main component is a fan of: AC motor. Its working principle is: energized coil in a magnetic field by the force of the rotation. Form of energy is transformed: the main electrical energy into mechanical energy, and because the coil has a resistance, so that there is an inevitable part of the electrical energy to be converted into heat. "220V AC Cooling Fan" Energy Efficiency and motor size, fan and power category have some relevance. Generally the larger the rated input power, the higher the value of energy efficiency requirements, energy efficiency in identifying when a look of standard models; second look at the rated input power; Third, look at the size of the value of energy efficiency. With the specifications "220V AC Cooling Fan", under the same power conditions the greater the value of energy efficiency "220V AC Cooling Fan" better performance.
