車輛空調系統是目前具有封閉車廂結構之車輛的必備裝置，可用以調整車廂內的環境溫度，例如提供涼爽或溫暖的車廂溫度。雖然目前的車輛空調系統都具備車內循環模式與車外換氣選項可供選擇切換，但絕大多數的駕駛人在開車期間很少會頻繁進行上述兩種模式的切換，通常都會讓車輛空調系統維持在車內循環模式，但是車內循環系統使用一段時間後，尤其是長途車程期間，車廂內的氧氣濃度會逐漸降低，此氧氣濃度降低的情況容易引發駕駛人精神變差的問題，而易肇生交通意外。The vehicle air-conditioning system is currently a necessary device for vehicles with a closed compartment structure, and can be used to adjust the ambient temperature in the compartment, for example, to provide a cool or warm compartment temperature. Although the current vehicle air-conditioning system has the option of switching between the in-vehicle circulation mode and the outside ventilation option, most drivers rarely switch the above two modes frequently during driving, and usually use the vehicle air-conditioning system. Maintain the in-vehicle circulation mode, but after the in-vehicle circulation system is used for a period of time, especially during long-distance driving, the oxygen concentration in the cabin will gradually decrease. This decrease in oxygen concentration will easily cause the driver to become mentally deteriorating. A traffic accident occurred.
