Control method for air conditioning system in motor vehicle involves reducing fresh air supply if carbon dioxide level falls below predetermined value

摘要

A temperature sensor (14) detects the actual temperature inside the vehicle. A dampness sensor (16) detects the humidity of air inside the vehicle. Cooling is performed based on the detected humidity and the comparison between the detected actual temperature and a desired temperature. The supply of fresh air (F) is reduced if the level of carbon dioxide detected by a carbon dioxide sensor (18) falls below a predetermined value.
