Abstract

An environmental control system is installed to dissipate the thermal load in avionic equipments that are mounted under an aircraft. The operating characteristics of the system change with variations in the control parameters. In this study, an environmental control system was designed and built using R-124 by adopting a vapor compression cycle. The operating characteristics of this system were observed by varying the control parameters, such as refrigerant charging amount, opening of the expansion device, compressor rotation speed, and blower rotation speed. The effect of the control parameters on the environmental control system was analyzed and an optimum control method was identified.

환경제어시스템은 항공전자장비로부터의 열부하를 제거하기 위한 목적으로 설치되어지며, 본 환경제어시스템은 제어변수의 변화에 따라 다양한 운전특성을 나타낸다. 본 연구에서는 냉매 R-124를 작동유체로 하는 증기압축 사이클 방식을 적용한 환경제어시스템을 설계 및 제작하였다. 냉매충전량, 팽창밸브개도, 압축기 및 송풍기 운전회전수와 같은 제어변수의 변화에 따른 환경제어시스템의 성능 및 운전 특성 변화를 실험하였다. 각 제어변수가 시스템에 미치는 영향을 분석하였으며, 최적제어를 위한 방안을 제안하였다.
