Abstract

In this study, the pleasant driving environment of the driver and passenger in the summer was investigated through the internal flow analysis of air due to the opening and closing of the car windows. The conditions on the entrance of the air conditioner with the opening and closing status of vehicle window were applied to the flow analysis by taking into consideration the actual driving environment. The automotive air conditioning outlet, the seat and the inside of car were modeled. As the air flow inside the car was analyzed, the air flow configuration and the temperature distribution were examined. In this analysis, the results were taken in consideration of only the effects of internal air and the opening and closing of window, assuming the interior of the vehicle as insulation. The analysis of each condition shows that these models maintain a pleasant environment. It is seen that this analysis result on the internal flow analysis according to the opening and closing of vehicle window can be applied by converging with the field of design.

본 연구에서는 자동차 창문의 개폐에 따라 공기의 내부 유동 해석을 통하여 여름철에 운전자와 동승자의 쾌적한 운전환경을 고찰하였다. 실제 운전 환경을 고려하여, 자동차 창문 개폐 상태로서의 에어컨 입구 조건들을 유동 해석에 적용하였다. 자동차 에어컨 토출구, 시트 그리고 실내를 모델링하였고, 차 내부에서의 공기유동을 해석하여 공기의 유동형상과 내부의 온도분포를 확인하였다. 본 해석에서는 공기 유입부와 배출구를 정하고 자동차 내부를 단열상태로 가정하고 내부공기와 창문 개폐의 영향만을 고려해서 결과를 보았다. 각 조건들의 해석을 고찰해보면 본 연구 모델들이 쾌적한 환경이 유지됨을 알 수 있었다. 차량 창문 개폐에 따른 내부에서의 유동에 대한 본 해석 결과는 디자인 분야에 융합하여 적용될 수 있다고 보인다.
