Common 220V AC Cooling Fan works

Axial fans are common "220V AC Cooling Fan" in essence, that the wind flows parallel to the blades of the rotating shaft. Fans of the main components are: AC motor. Its working principle is: energized coil in a magnetic field force and rotation. Electrical energy into mechanical energy, and because the coil resistance, so the inevitable "220V AC Cooling Fan" in part to be converted into heat energy. In addition, DC motors, brush less DC motors and other small power motors used in a small fan in the increasingly widespread. International energy shortages, domestic shortage also occur frequently, energy-saving features will be a direction of development can not be ignored. Potential evaporation principle work positioned between air conditioning and fan air-conditioning fan with water as the medium, the use of phase change material absorbs heat and water law, can send cold air below room temperature, while the built-in conventional heating source can send a warm and humid wind. In addition, with the battery "220V AC Cooling Fan" or the use of solar energy, energy conservation and environmental protection as a fan promotion and application will also be greater efforts in the future.
