Jigao Air Conditioning Repair Q&A; How does the air conditioning automatic control system work?
The automatic regulation of air conditioning uses instruments, meters, and computers to automatically adjust the air conditioning equipment without manual intervention. For example, the basic method for controlling the temperature in an air-conditioned room is like this: A temperature sensor placed in the room measures the changed indoor temperature, and the measured signal is input into the regulator where it is compared with the pre-set (desired) temperature. Then, based on the deviation, commands are issued to make the actuator perform corresponding actions, such as increasing or decreasing the opening degree of the control valve, changing the supply air volume, or adjusting the flow rate of chilled water, etc.
