Abstract

This paper is a study on integrated air-conditioning system for 1-ton class commercial vehicle based on electric vehicle. In the case of an electric commercial vehicle, since the opening and closing of the door is frequently performed in order to get in and out of the cargo, the heat loss largely occurs. Therefore, the heating and cooling load is required to be larger than the electric vehicle. As a result, the energy consumed by the heating and cooling system is larger than the passenger electric car in order to satisfy the heat comfort required by passengers. In order to overcome these disadvantages, we performed research using an efficient integrated air conditioning system. Finally, the design and analysis of a heat pump system for heating and a electrical compressor for cooling need to be proceed to develop a high-efficiency air conditioning system for improving the commerciality of 1 ton-class electric trucks and expanding the industrial ecosystem in the electric truck sector.

본 논문은 전기차 기반의 1톤급 상용차용 통합공조 시스템에 관한 연구이다. 전기 상용차의 경우 화물의 승하차를 위해 문의 개폐가 빈번하게 이루어지기 때문에 열손실이 크게 발생한다. 따라서 냉난방 부하가 승용 전기차에 비해 더 크게 요구된다. 결과적으로 승객이 요구하는 열 쾌적성을 만족하기 위해서 냉난방 시스템이 소비하는 에너지가 승용 전기차 보다 크다. 이러한 단점을 극복하기 위해 효율적인 통합공조 시스템을 적용한 연구를 수행했다. 최종적으로 1톤급의 경상용 전기트럭의 상품성 개선과 전기트럭 분야의 산업 생태계 기반 확충을 위한 고효율 공조 시스템 개발을 위해 냉방을 위한 전동식 압축기와 난방을 위한 히트펌프 시스템의 구상 설계와 해석적 검증을 수행한다.
