As shown in fig. 3 and 4, the side of the front air duct plate 222 may be provided with a power supply device electrode 225 for supplying power to the relevant device. In addition, a carbon dioxide sensor 226 may be further provided at the front portion of the front air duct plate 222 to detect the concentration of carbon dioxide. The concentration of carbon dioxide in buildings can have a significant impact on the health of people living and working in them, as even small levels of carbon dioxide, e.g., over 1200PPM indoors, can cause yawning and drowsiness.
Therefore, it becomes necessary to monitor the concentration of carbon dioxide. In some specific embodiments, an infrared carbon dioxide sensor, a catalytic carbon dioxide sensor, or a thermally conductive carbon dioxide sensor may be employed. The infrared carbon dioxide sensor detects carbon dioxide existing in the air by utilizing a non-dispersive infrared (NDIR) principle, and has good selectivity and no oxygen dependence. The catalytic carbon dioxide sensor converts the carbon dioxide concentration detected on site into a standard current signal and outputs the standard current signal. The heat conduction carbon dioxide sensor is manufactured according to the principle that the total heat conductivity coefficient of mixed gas changes along with the content of gas to be analyzed, two arms of a bridge are formed by matching a detection element and a compensation element, the resistance of the detection element is reduced when the detection element meets combustible gas, the resistance of the detection element is increased when the detection element meets non-combustible gas (air background), the bridge circuit outputs voltage variable, the voltage variable is increased in direct proportion along with the increase of the gas concentration, and the compensation element has the functions of reference and temperature compensation. It should be noted that the above-mentioned type of carbon dioxide sensor 226 is merely exemplary and not limiting, and in other embodiments, other types of carbon dioxide sensors 226 may be used.
