Simulation of fan coil based on fuzzy control in solar heating fresh air system

Based on the solar heating fresh air hardware platform and matlab/simulink modeling environment, the design and realization of fan coil simulation is accomplished in fresh air system. Firstly, the working principle of this experimental system is introduced, and in the meanwhile, its mathematical model and simulation are given in this paper. At last, with the adding of fuzzy control algorithm, the system can provide stable fresh air temperature according to different setting temperatures. The result of simulation fairly meets the actual experimental data, proving the applicability of fan coil modeling and the effectiveness of fuzzy control algorithm.
