New Solutions for Improving the Vehicle Heating System

Abstract

The specific requirements of the air-conditioning system are in connection with maintaining the optimal thermal comfort for the vehicle occupants and providing a good visibility through the windscreen. This is a real challenge due to the extreme weather conditions experienced across the globe. The heating method, by using the cooling system of the engine, takes a lot of time to heat the interior air. Auxiliary electrical and booster devices are proposed to improve the heating of the vehicle compartment. The paper is focused on analyzing the different technologies available and developed in order to provide the heat necessary for assuring the thermal comfort of vehicle passengers. Measurements on a PTC heater are made and analysed.
