Abstract

This paper discusses the development of the wearable personal cooling system for reducing thermal stress in hot environment. The personal cooling system is operated with the compact refrigeration system by compressing refrigerant. The compact refrigeration system is applied with the miniaturization and weight reduction for portable and wearable cooling system. The body heat is reduced by heat conduction with evaporator in direct cooling type. The cooling capacity of the wearable personal cooling system is approximately 100W and, the system could maintain the inside temperature of approximately 12-$13^{\circ}C$ lower than the ambient temperature. The weight of the wearable cooling system is about 3kg including vest, case, battery and all parts.

본 논문은 더위나 고온의 환경에서 열적스트레스를 줄이기 위한 착용형 개인 냉방시스템 개발에 관한 것이다. 개인 냉방시스템은 냉매압축 냉동사이클로 작동되는 소형 냉동시스템이 적용되었다. 소형 냉동시스템은 이동과 착용이 가능하도록 소형화와 경량화에 맞게 구성되었다. 증발기는 나일론튜브를 사용하여 조끼 내부에 매립하여 열전도에 의해 신체 열을 저감시키는 직접냉각방식이 적용되었다. 착용형 개인 냉방시스템은 냉방능력은 대략 100W이며 주위온도보다 12~$13^{\circ}C$ 정도 낮게 유지되는 성능을 가진다. 착용형 개인 냉방시스템의 무게는 조끼, 케이스, 배터리를 포함하여 약 3kg이다.
