Abstract

Disclosed is a heating and/or air-conditioning system for a vehicle and a method for adjusting a recirculating air fraction of the inlet air delivered to a passenger compartment of a vehicle in order to avoid exceeding a predetermined limit value of at least one air parameter, in particular the carbon dioxide fraction and/or the humidity in the passenger compartment air. The method provides that one or more secondary parameters be obtained and analyzed for indirect determination of the air parameter, and that the recirculating air fraction be adjusted as a function of the analysis.
