Abstract

The objective of this study is to investigate performance characteristics of the thermal management system for passenger hydrogen fuel cell vehicle under various operating conditions. The thermal management systems comprised of a stack cooling system, an electric device cooling system and an air conditioning system for a passenger room were tested with driving conditions. As a result, in highway driving mode, the cooling performance of the stack cooling system with air conditioning on condition was 28.8 % lower than that of the air conditioning off condition. And cooling load of the electric cooling system in the city driving mode was 65.6% higher than that of the highway driving mode.

본 연구의 목적은 수소연료전지 자동차의 열관리시스템 성능특성을 알아보기 위하여 다양한 운전조건 변화에 따른 열전달 성능특성을 고찰하는 것이다. 수소연료전지 자동차의 열관리시스템으로 스택 냉각시스템, 전자장비 냉각시스템, 그리고 냉방시스템의 성능특성 및 상호영향도를 파악하기 위하여 자동차 실 도로 운전조건 변화에 따른 냉방성능 및 전자장비 냉각시스템에 미치는 영향을 파악하였다. 결과적으로, 고속도로 조건에서 냉방시스템 작동 시 수소연료전지 자동차의 스택 냉각시스템의 방열성능은 냉방시스템이 꺼진 경우보다 평균 28.8% 감소하였고, 시내주행 조건에서 수소연료전지 자동차의 전자장비 냉각시스템의 냉각부하는 고속주행 조건보다 약 65.6% 상승하였다.
