- Abstract
In order to improve the efficiency of central air conditioning, save energy and reduce emissions, the design of variable air volume (VAV) automatic control system for central air conditioning is studied. Firstly, the principle and method of VAV control system of central air conditioning are studied and analyzed. Secondly, aiming at the problem of poor selflearning adaptability of the traditional VAV control system of central air conditioning, it is proposed that the BP neural network based on intelligent algorithm can be used to improve it. Finally, the performance of the VAV automatic control system of central air conditioning improved by intelligent algorithm is tested. The results show that the VAV of central air conditioning mainly depends on the adjustment of terminal controller. BP neural network can be used to modify the linguistic value universe and the corresponding membership function of the terminal controller algorithm, which makes the output of the control algorithm more perfect, thus improving the intelligent degree of the VAV control system for central air conditioning. The test results of the improved VAV control system show that the anti-interference ability and the ability to reduce energy consumption have been significantly improved, and the transition time of the system has also been significantly reduced, which proves the effectiveness of the improved algorithm. It is hoped that this research can provide some reference for improving the VAV automatic control system of central air conditioning and improving the energy saving and emission reduction efficiency of the air conditioning system.
