Abstract

In the current context of “peak carbon emissions and carbon neutral”, today’s society has put forward higher requirements for reducing building energy consumption. Therefore, to address the problems of high energy consumption and poor comfort of central air conditioning system in large public buildings, this paper proposes an energy-saving control method for fan coil unit based on auto-counting of people number to reduce the operating energy consumption of air conditioning system as much as possible while meeting the comfort of indoor personnel. It is concluded that the operation strategy can effectively reduce the operational energy consumption of the air conditioning system by 20%. It is applicable to the central air conditioning system of public buildings with large changes in the number of people, and has certain application prospects.
