NEW METHODS FOR EVALUATION OF THE THERMAL ENVIRONMENT IN AUTOMOTIVE VEHICLES.

Author(s) : MADSEN T. L., OLESEN B., REID K.

Summary

THE INVESTIGATION WAS CONDUCTED IN A WIND TUNNEL WHERE AIRSPEEDS OF UP TO 130 KM/H (36 M/SEC) WERE ACHIEVABLE AT TEMPERATURES BETWEEN 255 AND 313 K (-18 AND 40 DEG C). A REALISTIC SUN LOAD ON THE CAR WAS ALSO SIMULATED DURING THE TEST. 3 TECHNIQUES HAVE BEEN TESTED: AIR TEMPERATURE SENSORS AT FEET AND HEAD LEVEL ; THERMAL COMFORT SENSORSMEASURING THE EQUIVALENT TEMPERATURE AT FEET, ABDOMEN AND HEAD ; AND A THERMAL MANIKIN MEASURING THE EQUIVALENT TEMPERATURE OR HEAT LOSS FOR 16 BODY SEGMENTS. THE THERMAL MANIKIN IS HEATED AND THERMALLY SIMULATES A HUMAN BEING. THE SUN'SRADIATION CAUSES AN ASYMMETRIC THERMAL LOAD ON THE PERSONS AND THE SEATS THERMALLY INSULATE A PART OF THE BODY. THESE FACTORS ARE NOT TAKEN INTO ACCOUNT IF ONLY AIR TEMPERATURE IS MEASURED. THE PAPER PRESENTS AND COMPARES RESULTS FROM ALL THE METHODS.
