인체생리모델에 기반한 탑승자 온열쾌적감 예측방법의 개발

초록

In this study, we have developed HMC(Hyundai Motor Company) comfort model that predicts drivers’ thermal comfort in vehicle cabin. HMC comfort model is based on the subject experiment. To develop this model, two different kinds of experiments were conducted. One is in the experiment climatic chamber, and the other is in the car on the rooftop. In both experiments, drivers’ body temperatures and psychological comfort votes were measured with indoor environment. The experiments in the climatic chamber were conducted under the two identical conditions(hot and cold). The experiments on the rooftop were conducted for 8 months (except on rainy days) from July to February which is summer (7~8), autumn (10~12), and winter (1~2). The car was on top of the roof in the consideration of solar radiation. Total 195 male subjects who has normal body fat ratio (10-20%,±3%) participated in this experiment; subjects for valid data were total 187(33 for chamber experiment and 154 for rooftop experiment). Experimental clothing that the subjects wore was 0.41clo(summer), 0.57clo(autumn), 0.74clo(winter) for each season. This paper suggests the basic concept of the HMC comfort model, and its development conditions, partial results and future plans.
