Energy-saving control method of fan coil by human body induction

The invention relates to a fan coil of a central air conditioner, in particular to an energy-saving control method of a fan coil by human body induction. In order to solve the technical problems thatthe fan coil can not be automatically controlled or automatically judged and the like, the invention provides the energy-saving control method of the fan coil by human body induction, which can enablethe fan coil to automatically control and judge whether people exist or not to provide needed operating conditions, thereby achieving the energy-saving effect. The invention mainly adopts the modes of human body induction control, dynamically-balanced electric two-way valve control, temperature difference control and the like to achieve the purpose of energy saving.
