A large shopping mall in Shanghai has installed more than 100 sets of EVE2100 electronic intelligent valves on the main air conditioning pipe and regional branch pipes. The smart valve's own pressure, temperature, temperature difference, pressure difference, flow, heat and other sensor data are uploaded to BA for monitoring, and combined with big data analysis, remote control commands are given. The valve combines AI technology with its own PID self control, combined with edge computing to reduce the comprehensive computing power, so as to make the hydraulic balance between the central air-conditioning circulation pipe networks, Directly reduce energy consumption in winter and summer, improve the satisfaction of heating users, and directly reach a good balance between the property company and users.
