Modeling and simulation of the PTC heater used in automotive

At present, efforts are made to improve the passenger’s thermal comfort inside the vehicle. The thermal comfort level depends on the air conditioning and heating system. The conventional heating systems use the heat excess delivered by the vehicle’s engine. Nevertheless, this heat excess is insufficient for warming the interior air to a comfort level. In order to improve the conventional heating method, auxiliary heating devices are required. The paper deals with the analysis and measurement of the PTC heater characteristics. A test-bench is described. The heating process inside the vehicle is analyzed and a model and simulations are also presented.
