A vehicle cabin air conditioning system includes an airflow system comprising an airflow apparatus, such as HVAC assemblies (34,36, figure 2), to direct an airflow through one or more air vents in the cabin. The vehicle system also has: an interface comprising first and second input modules (28, figure 4), each module being configured to issue an airflow demand signal in response to user input; and a controller. The controller is configured to receive an airflow demand signal (e.g. a desired flow rate) issued by either of the first and second input modules in response to user input and determine, in accordance with the received signal, an airflow map 60 defining a function of an airflow parameter (e.g. flow rate and/or power level of a fan) with respect to a cabin temperature and/or a cabin heating power demand. The controller operates the airflow system in accordance with the determined airflow map 60 to control the airflow through the vent(s). Determining the air flow map may comprise selecting the airflow map from a set of airflow maps or adjusting a single airflow map in a dynamic manner in response to the user input.
