The invention relates to a central air-conditioning refrigeration room group control management system, through a monitoring computer, an information input and output device connected to the monitoring computer and an Ethernet switch; the Ethernet switch is connected with a serial port server, a PLC controller, and a host valve control box group, Refrigeration pump control cabinet group, cooling pump control cabinet group, cooling tower control cabinet group, cooling tower valve control box group; PLC controller is connected with temperature sensor, pressure sensor, flow sensor and outdoor atmospheric temperature and humidity sensor; refrigeration pump control cabinet includes The refrigeration pump start-up circuit controls the start-stop and speed regulation of the refrigeration pump; the cooling pump control cabinet contains the cooling pump start-up circuit and controls the start-stop and speed regulation of the cooling pump; the cooling tower control cabinet contains the cooling tower start-up circuit and controls the cooling tower The technical solution of start-stop and speed regulation control solves the technical problems of low automation and cannot ensure the balanced operation of each equipment, and is suitable for refrigeration room systems with various pipeline connection topologies.
Description
technical field [0001] The invention relates to the field of industrial control, in particular to a central air-conditioning and refrigeration room group control management system. Background technique [0002] In modern buildings, more and more central air-conditioning systems are used, and the power consumption of the refrigeration room accounts for a considerable part of the total power consumption of the building. For commercial buildings, such as office buildings, shopping malls, and hotels, the power consumption of the refrigeration machine room can reach 30-35% of the total power consumption of the building. The same situation also occurs in industrial occasions. The refrigeration room is mainly used for air conditioning systems or process cooling requirements, and it also accounts for a considerable proportion of the total energy consumption of the factory. For example, in textile factories and electronic semiconductor factories, the operating power consumption of th...
