Abstract

In this paper, we developed a cooling system for the refrigeration truck using natural carbon dioxide refrigerant which is attracting attention as an environmentally-friendly refrigerant. We developed a high efficient environmentally-friendly refrigerated truck that converted the existing diesel vehicle into an LNG vehicle to improve emissions of truck and improved the efficiency of the cooling system by utilizing a heat of LNG vaporization. The COP of refrigerated truck system was increased 144%.

본 논문에서는 자연냉매로 주목받고 있는 이산화탄소(CO2) 를 이용하여 냉동탑차용 고효율 냉동시스템을 개발하였다. 기존의 디젤 차량을 LNG 차량으로 개조하여, 화물차의 배출가스를 개선하고, LNG 연료의 기화 잠열을 활용하여 CO2 냉동시스템의 효율을 높인 친환경적인 냉동탑차를 개발하였다. 그 결과 가스 쿨러에 LNG연료의 기화 잠열을 활용하여 냉동탑차의 COP를 144%로 향상 시켰다.
