1. A method for operating an air conditioning system for a vehicle for transporting passengers, the method comprising:
determining a total water mass flow that is currently being produced by the passengers in a passenger compartment of the vehicle on a basis of air-conditioning measurement values and a current value for at least one operating parameter of the air conditioning system;
determining, from the total water mass flow and a predefined value for a water mass flow produced by one passenger, a current number of passengers in the passenger compartment; and
controlling, with the air conditioning system comprising a plurality of sensors, a fresh air volume flow to be introduced into the passenger compartment from outside the vehicle in order to maintain a predefined minimum compartment air quality in dependence on the current number of passengers in the passenger compartment of the vehicle.
