환경차 연비 증대를 위한 고효율 HVAC 시스템 개발

In these days, major car makers fiercely compete developing high fuel efficient green car, because of increasing people’s concern about environmental problem. One of main factor of low fuel efficiency is climate control system. So in this paper, we researched new technologies to improve fuel efficiency of a green car. The technologies are 1) individual climate control, 2) fresh and recirculating air contol system, 3) developing optimized PWM blower motor and 4) fuel efficient climate control logic. By these technologies, we can inhance mileage of a green car and lower CO₂ emission.
