Aspects of Modeling and Optimizing Air Circulation Currents in a Car Cabin

Air conditioning system is one of the main components of modern cars, which defines the level of comfort, its performances directly affecting the car performances. In order to have a car with high level of thermal comfort, the air-conditioning system must be efficient in terms of energy, it has to perform many functions regarding the microclimate control (control of temperature, humidity, filtration), and in addition must fulfill safety and security functions in circulation (demisting and defrosting). Also vehicle air-conditioning system can significantly influence fuel economy and tailpipe emissions of conventional and hybrid electric vehicles (HEV) and reduce electric vehicle (EV) range.
