With the rapid development of industrial automation, system such as DCS, PLC controller has been widely used in industrial. The installation of a DCS, PLC, counters, the terminal counters, and other key operating station of the central control room makes control equipment and electronic devices to be a true core of factories or the the enterprise. At the same time on the operating reliability of electronic equipment also has set higher requirements. How to improve the safety and reliability of electronic equipment is as to protect devices such as DCS, and other electronic module running in the high temperature environment from breaking down. One of the important and effective methods is to improve environment of the electronic equipment, while improving the working environment of operation and maintenance to improve monitoring, operation quality. For this reason, more and more factories deploy air-conditioning control room.
As one of the measures to conserve energy, use of the waste heat boiler over hot water and steam to run central air conditioning, are increasingly being thermal power plants, chemical plants and other projects and the new technology projects adopted. Such is the system for the centralized monitoring and air conditioning design.

The thermal power plant control system is mainly concentrated air-conditioning control system of the following: (1) Set-floor cooling heating system. (2) Heating Station heating system. (3) centralized control room and electronic equipment of air-conditioning systems. (4) Set-floor electrical room cooling ventilation system. (5) Steam Electric power distribution between the engine room and battery room (0.00 m, 6.30 m layer) ventilation and air conditioning systems. (6) excitation of the main ventilation and air conditioning plant. (7) Air-cooled air conditioning and ventilation systems between inverter. (8) Steam Room 6.3 m air supply and exhaust systems roof.
Air conditioning systems and centralized control by the central management of workstations, communications networks, controller (PLC), the control cabinet and ancillary equipment (in situ detection instruments, meters and pipe valves and instrumentation, transmitter, the electric doors, inverter, power distribution box and electric implementing agencies), etc.. System Components indicative figure:

Air conditioning centralized control system uses distributed control architecture: central management station operating parameters to achieve the establishment, control strategy changes, running surveillance, historical data records, and through the TCP / IP communication protocol to the Ethernet communication I for two-way communication with the DCS, the DCS to achieve centralized control system monitoring the air-conditioning purposes; measured by operating station under indoor and outdoor air temperature and humidity, the calculated indoor air temperature and humidity, the enthalpy value, thereby calculated enthalpy difference, the calculated air-conditioning the load. According to the outdoor air enthalpy frequency map of the air conditioning running condition Division, from outdoor air enthalpy value of all district and the critical point of comparison enthalpy value judgment outdoor air condition their air-conditioned condition, the air conditioning division operating conditions, depending on the operating conditions of the area using different parameters, the air-conditioning throughout the year to achieve the status of energy-saving operation of the Multi-control. Operating station control strategy downloaded to the PLC control cabinet, PLC operated stations under the control strategies and set up the parameters, focus on the acquisition of real-time data elements, the implementation of the necessary operations, the completion of all the control functions.
