연료전지 자동차용 CO₂ 전동식 냉방 시스템 개발에 관한 기초 연구

The main objective of this work is to investigate the characteristics of the mobile air conditioning system for fuel cell electric vehicle (FCEV). The present air conditioning system for FCEV uses the electrically driven compressor for CO₂. The experimental work has been done with various operating conditions such as different compressor speed and high pressure to identify the characteristics of the system. Experimental results show that the cooling capacity was more than 3㎾ and coefficient of performance (COP) was more than 1.5, also.
