An overview of the

Air cooling unit cold end security and optimize system mainly through the empty cold coagulation (cooling tube bundle temperature field to realize online monitoring of condensation in the air cooling system (cooling), are installed on the temperature measurement sensor, collection of air cooling island () between the cooling tower of wind speed and peripheral environment parameters, to control between cold air cooling fan and shutter, All signals of the system are transmitted by optical cable to ensure that there is no electrical connection between the intelligent front end and the background monitoring equipment, and the system is reliable. At the same time, other relevant data in the DCS system can be combined. In the optimization control station to process data and adjust the air cooling fan speed or shutter opening to the DCS control system, to achieve safety and optimization of closed-loop control, can also do and DCS mutual backup, complementary functions.

System structure

The system function

● In the spring and autumn season, guide the optimized operation of air cooling unit, which can play the role of energy saving, efficiency improvement and emission reduction for air cooling unit.

● Deep winter season, prevent tube bundle freezing phenomenon, avoid major maintenance loss.

● Judge hot air backflow phenomenon in summer, analyze and prevent hot air backflow.

● Condensing tube bundle cleanliness diagnosis function

Main Functions of software

● Electronic map: intuitively view the location of temperature measurement point, accurate positioning of low temperature point.

● Real-time report: real-time view the current data, save, print real-time data report.

● Historical data query: the software uses monitoring data hard disk, can save 1 year of all data, convenient data analysis.

● Historical data report form: provide historical data form, convenient to record.

● Real-time alarm: view the real-time alarm situation, can quickly analyze and deal with the fault.

● Historical alarm query: easy to query and summarize alarm information, analysis and judgment of operating status.

● Early warning and site control.
