Modeling and Simulation of Fresh Air System with LHTS and Solar Energy

Abstract:State of the research about the technology of solar energy with LHTS (Latent Heat Thermal Storage) at home and abroad was firstly introduced, and a fresh air system with solar energy and LHTS was then introduced. After that the fuzzy control system of fresh air temperature was studied. Firstly, a mathematical model of the fan coil was built as the controlled plant. Then, a fuzzy controller was designed and applied to control the fresh air temperature with the features of high non-linearity, large disturbance and uncertainty of fresh air system. Finally, the simulation was realized on the mathematical model of the fan coil. It proves that the fuzzy control system has a high accuracy in stability and is able to resist interference. This research will be helpful for fuzzy controller design of the fresh air system.
