Applying Research of the Control Strategy and Algorithm System on Intelligent Buildings

According to the application situation of VAV air-conditioning system in China, this paper designed the experiment installation of intelligent control VAV air-conditioning system which was based on BAS of Web-Ctrl of ALC (Automated Logic Corporation). The compositions and characteristics of this installation were analyzed and the hardware and software, the control strategy of the installation were presented, this paper made use of the control modules of American Automated Logic Corporation to establish applicable algorithmic modules such as the pressure-free VAV Box control, the supply fan variable frequency control, the supply air temperature set-point optimized control, the system operating time and demand control and the supply air temperature and humidity control etc. The arithmetic made the VAV air-conditioning system reach notable energy-saving and feasible anticipated effects.
