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.
Description
technical field [0001] The invention relates to a central air-conditioning fan coil unit, in particular to a human body induction energy-saving control method for the fan coil unit. Background technique [0002] Fan coil unit is an ideal terminal product of central air-conditioning, and fan coil unit is widely used in hotels, office buildings, hospitals, commercial and residential buildings, and scientific research institutions. The fan coil unit is mainly composed of a low-noise motor and a coil. The fan cools or heats the indoor air or outdoor mixed air through the surface cooler and sends it into the room to lower or increase the indoor temperature to meet people's comfort requirements. The cold (hot) medium water in the coil is centrally supplied by the machine room. The control of fan coil units mostly adopts the scheme of local control, which is divided into two types: simple control and temperature control. Simple control: Use the three-speed switch of the fan to d...
