Automatic control system of evaporative cooling semi-centralized air conditioning system

Presents the flow process of evaporative cooling semi-centralized air conditioning system. Based on operation modes of different seasons, designs the automatic scheme to guarantee the system’s safety and energy efficiency. Presents the control content and hardware configuration in detail. Achieves the communication between the personal computer and the programmable logic controller by configuration software, realizing the functions of centralized control, data logging and printing, so as to provide detailed data for on-site equipment maintenance worker and to simplify operation and maintenance. The project application shows that the control system works steadily and achieves a desired effect.
