Smart Energy Management System

SEMS, a complete system for AC room, which can make the temperature and humidity of workshop follow the setting point and control them more precisely. The temperature and humidity of environment, supply air, return air, water and workshop can be collected all the time, and then the controller will calculate the data according to the requirements, then the fan speed, shutter switch angle and pump spraying effect will be adjusted in real time through PID.

1)Five temperature sensors and five humidity sensors are added to SEMS for AC Room (see image below).

2)All the motors are controlled by special inverters.

3)All the shutters are controlled by the servo devices.
