AI Technical Summary
Existing air conditioners that use dust sensors to detect oil fumes are costly, and the fumes may damage infrared or laser devices, affecting the reliability of the detection.
The TVOC detection unit, including a heating subunit and a sensing subunit, detects pollutants in the air by measuring the difference between the actual resistance value and the initial resistance value. It uses a low-cost metal oxide sensor chip to avoid the influence of oil fumes.
It reduces the cost of air conditioners, improves the stability and accuracy of oil fume detection, can quickly identify the types and concentrations of pollutants, intelligently adjusts the operating status of air conditioners and range hoods, extends the life of air conditioners, and saves energy and reduces emissions.
