Low-Energy-Consumption Operation Debugging Method of Large-Scale Gymnasium HVAC System Based on Physical Sensor Network

In order to achieve the goal of low-energy operation of HVAC in large stadiums, a building central air-conditioning energy-saving monitoring network based on physical sensor network technology has been developed, which can realize real-time monitoring and control of central air-conditioning systems in large public buildings or building groups. The network nodes form a self-organizing wireless sensor network according to the IEEE802.15.4/ZigBee protocol, using wireless temperature, humidity and other sensors to provide temperature and humidity in the building environment, water supply and return water temperature on the secondary side of the power center plate heat exchanger, etc. Perform real-time acquisition. The on-site operating parameters are transmitted to the upper computer of the monitoring center through the GPRS network, which realizes the energy-saving management and optimization control of the entire system operation by the upper computer.
