An exploration of modeling in central air-conditioning intelligent control system for saving energy

The complexity of system modeling is very typical in central air-conditionings, especially when considering the multi-working-condition sub-areas, multi-parameters and time delay problems, the complexity of mathematical model will greatly increase. Under the state, the question of how to obtain the correct model, whose error with the practical system is in the acceptable range, becomes more practical and theoretical meaningful. Through theoretical analysis and experimental conclusion, the paper simplifies the air-conditioning room to a single content plant with some self-balance capacity. The paper discusses the production of time delay and its effect. It considers the pertinence of temperature and moisture, at the same time the paper compares the intelligent optimal control algorithm with system PID control algorithm. These researches are very meaningful for the following work.
