Simulation study on the performances of different FCU control logics

Fei Xue, Kelin Li, Fulin Wang

Abstract: The paper studies the performances of three different Fan Coil Unit (FCU) control logics using simulation. One of them is to open/close water valve to meet temperature set point, which is the conventional control logic. Another control logic is to open/close water valve according to a duty ratio decided by a fuzzy logic. The third one is a new control logic proposed by this paper, which controls fan speed level and water valve duty ratio to meet both temperature and humidity set points. The simulation results show that the proposed control logic can achieve better control performance than the previous two control logics.
