냉난방 성능향상을 위한 인테이크 도어 제어 연구

Recently, the quick heating performance is the big issue in the vehicle because engine performance is high. So car makers adapted the additional heating devices (ex. PTC heater). As quick cabin cooling performance is recorded in the IQS, it is an important issue, too. In this study, the HVAC intake door control is studied for quick heating and cooling performance. In case of the heating performance, it improves 4.0℃ at -20℃ ambient after 20 minutes. And in case of cooling performance, it improves 1.5℃ at 35℃ ambient after 10 minutes. In addition, intake door control system brings on the cost reduction about 200 won because the flab door is eliminated. In present, intake door control system is adapted all HKMC new developing car.
