Vehicle manufacturers have to strive continually for higher levels of customer satisfaction in order to increase, or at the very least consolidate, their market share. In order to achieve the required levels of climate comfort, it is essential that heating and air conditioning sub-systems are incorporated iota an effective cabin ventilation system. Interior airflow distribution, overall air flow rate though the vehicle, and the ratio of body leakage to extract flow, all have a direct hearing on the control of the vehicle's interior climate. Peer body sealing, and incorrectly sized and located extract vents can lead to inadequate airflow through the vehicle, and peer spatial temperature distribution. This leads to unacceptable levels of heating and A/C performance as determined in Climatic Wind Tunnel tests, and failure to meet occupant comfort targets. Furthermore, there are critical safety issues associated with the design of the ventilation system; driver tiredness is obviously a major issue. This paper focuses on two important areas - interior airflow and front-end cooling pack heat transfer - and in particular, the way in which these aspects of thermal management can be developed by means of laboratory experiment. Specifically, results arising from studies conducted in the thermofluids laboratory, and the ways that these data can be best utilised are discussed.
