220V Cooling Fan shortcomings

"220V Cooling Fan" as the ambient temperature changes can not automatically adjust speed, temperature difference between day and night that those areas are fatally flawed, especially when people are sleeping, not only a waste of resources, very easy to make cold sick; traditional electric the timing of the fan machinery is often accompanied by the sound of mechanical movement, especially at night affect people's sleep, and limited time range, can not meet people's needs. Given these drawbacks, we need to design an intelligent "220V Cooling Fan" temperature control system to solve. Temperature-controlled fan system is to automatically open and close the fan according to the prevailing temperature conditions, it can be very good save energy, but also facilitate the users to use more humane. And in industrial production, daily life has widely thermostat "220V Cooling Fan" systems, such as cooling systems in large-scale industrial production of machinery and equipment, or limit intelligent CPU fan on the laptop and other microcontroller-based temperature-controlled fan We are able to start the level automatically according to ambient temperature or stops, and to achieve speed automatically adjusted according to temperature changes, with a very wide range of uses in real life, so "220V Cooling Fan" designed with a certain sense of value.
