Cooling system of electromechanical chamber based on improved PID algorithm

In view of problem of high temperature thermal damage of electromechanical chamber of deep mining mines, the paper designed a set of cooling system for electromechanical chamber with low wind speed and humidity, which can realize automatic adjustment of cooling capacity. It introduced hardware design and PC software design of the system, and described dead zone incremental digital PID algorithm embedded in PLC in details. The application results show that the system can effectively reduce indoor temperature of electromechanical chamber, and achieves functions of automatic control of cooling capacity, ground monitoring, alarming and warning.
