Abstract
A method for operating an air-conditioning system that carries out an air quality testing cycle is disclosed. The air quality testing cycle includes: Step A: testing if the current pollutant concentration is below a predetermined first pollutant limit value; Step B: in the event that it is determined in the Step A that the current pollutant concentration is below the first pollutant limit value, testing if the bypass device is completely open or if the current flow rate of the blower device corresponds to a current air volume demand of the air-conditioning system; Step D: in the event that it is determined in the Step B that the bypass device is not completely opened or that the current flow rate does not correspond to the current air volume demand, testing current pollutant concentration is below a predetermined second pollutant limit value that is smaller than the first pollutant limit value.
