Does Mercedes-Benz Require Air Conditioning to be Turned On for Internal Circulation?
1 Answers
Mercedes-Benz does not necessarily require the air conditioning to be turned on for internal circulation, but turning on the air conditioning does require internal circulation. The usage scenarios of internal and external circulation and the role of internal circulation are as follows: Usage scenarios of internal and external circulation: Car air conditioning systems generally have switches for internal and external circulation. When external circulation is used, the air conditioning draws air from outside the vehicle, while internal circulation reuses the air inside the car. It is best to alternate between internal and external circulation. External circulation can be used when the outside air is good and of high quality, as without the renewal of outside air, the air inside the car will gradually become stale. Internal circulation can be used when the outside air is poor, contains exhaust fumes, or is at a high temperature. Role of internal circulation: Internal circulation can enhance the effectiveness of the air conditioning, essentially recooling the already cooled air inside, which improves the air conditioning performance. However, prolonged use of internal circulation can degrade the air quality inside the car, leading to feelings of dizziness and discomfort. It is advisable to use internal circulation for a while and then switch to external circulation for a few minutes to allow fresh air to enter the car and improve air quality.
